Industrial Engineering in Agricultural Engineering

 


What is Agricultural Engineering?


Agricultural engineering, also known as agricultural and biosystems engineering, is the field of study and application of engineering science and designs principles for agriculture purposes, combining the various disciplines of mechanical, civil, electrical, food science, environmental, software, and chemical engineering to improve the efficiency of farms and agribusiness enterprises[1] as well as to ensure sustainability of natural and renewable resources.[2]


An agricultural engineer is an engineer with an agriculture background. Agricultural engineers make the engineering designs and plans in an agricultural project, usually in partnership with an agriculturist who is more proficient in farming and agricultural science.

Industrial Engineering Philosophy - Delaney

 





Industrial  Engineering is essentially a philosophy with a materialistic and a human  aspect.

 The materialistic aspect  is  based on the conception that business of enterprise can only succeed  if it renders a real service. To serve people, then, industry must make  products that people can buy. The only way a service or product can  get wide distribution is by making its cost low. The main obstacle to  low cost is waste — waste of time, of material, of energy.


If methods of tasks are not evaluated for the time taken, some or many tasks may use  the  complicated and time consuming elements.  The basic aim of the Industrial Engineer is that of saving time. Eor  this, he uses the strictly objective approach compounded of two elements  which are ANALYSIS and MEASUREMENT respectively.  They bring imagination, discovery and ingenuity down to rational terms.

 Through ANALYSIS of tasks, a vast lot of isolated and apparently unrelated pieces of information and phenomena are uncovered within the task as well across tasks. These are  brought together, sorted out and compared. Theories are evolved regarding elements common across tasks and  further observations are made until some practical solution that takes less time is found.  Typical of the analytical phase are the several techniques of method  study ranging from the flow process chart to the micro-motion study.  Here, analysis is used to eliminate waste of time and effort. The job  is simplified: back-tracking is avoided, unnecessary handling is eliminated, short cuts are taken, the design is changed to save material.


 Using MEASUREMENT  procedures are evaluated  in terms of time and cost. Time study is industry's tool for measuring the productive capacity of its human and mechanical resources. It is the  measurement of work and one of its end result is a number which expresses  the time that should normally be taken to complete a given task. Time  study is concerned with the question: "How long should it take ?" along with  "How long does it take ?" That is a vastly different matter which  calls for skill, judgment and careful training. Not only the time taken  has to be recorded accurately but the effect of working pace on that  time has to be appreciated. This is called "performance rating".  


We might say that through his techniques, the Industrial Engineer  creates time.  In the present instance, the "fait accompli" is the  steady increase in the productivity per individual and per unit of resource in industry.  where. It is safe to say, on the basis of all available data, that production per average individual is increasing at the rate of about 3 percent  per  year. It is what makes possible the shorter hours and higher wages.

 Where will it lead us, no one can foresee or dares to foretell. Yet, an  article published in "Business Week" June 1952, is quite revealing.  It deals with the astounding results and implications of farm mechanization. In the span of a generation, over two million men have been  dropped from farm employment and, yet with almost no increase in  tilled acreage, our (North America's) farm output has increased by 40%  and our output per worker by 60%. Since 1920, the output per man  hour has doubled.

Industrial Engineering is Engineering Plus Productivity - Industrial Engineering Philosophy


INDUSTRIAL ENGINEERING PHILOSOPHY


I would like to state the philosophy of industrial engineering as engineering systems can be redesigned or improved and installed periodically for productivity increase or improvement. The primary drivers of productivity improvement are developments in basic engineering disciplines and developments in industrial engineering (developments in productivity science, productivity engineering and productivity management). The additional drivers are developments in related disciplines, for example, economics, mathematics, statistics, optimization techniques, ergonomics, psychology and sociology etc. - Narayana Rao, 1 April 2021.

Process Industrial Engineering = Process Design Engineering + Process Productivity Philosophy - Science - Engineering - Management


Facilities Industrial Engineering = Facilities Design Engineering + Facilities Productivity Philosophy - Science - Engineering - Management

Human Effort Industrial Engineering = Mechanic Arts + Human Effort  Productivity Philosophy - Science - Engineering - Management



Productivity Philosophy - Science - Engineering - Management in engineering formally started as important activities in the first annual convention of ASME.  May be we can look for call for productivity and cost reduction of engineered products in some earlier engineering writings also. But the ASME presidential lecture (1880) is a formal call for the engineering community and it was answered with a solutions provided by various members of  the ASME in subsequent years.

The concern for management and productivity issues  occupied the attention of the first ASME  president. Thus ASME's attention to the topic is there right from its founding . In fact, R.H. Thurston  the first ASME president, in his inaugural address (1880), included productivity improvement  and  economy among the objects of the society in his inaugural address. 

"We are now called upon to do our part in the work so well begun by our predecessors, and so splendidly carried on by our older colleagues during the past generation. We have for our work the cheapening and improvement of all textile fabrics, the perfecting of metallurgical processes, the introduction of the electric light, the increase of facilities for rapid and cheap transportation, the invention of new and more efficient forms of steam and gas engines, of means for relieving woman from drudgery, and for shortening the hours of labor for hard-working men, the increase in the productive power of all mechanical devices, aiding in the great task of recording and disseminating useful knowledge; and ours is the duty to discover facts and to deduce laws bearing upon every application of mechanical science and art in field, workshop, school, or household."  - Thuston. R. H. Thurston. President's inaugural address. Transactions ASME, 1, 1880, pp. 14-29.




Industrial engineering department was advocated by F.W. Taylor as a department that improves engineering elements based on experiments and science that was motivated by shop operations experience to increase productivity and reduce costs. He termed the department as "elementary rate fixing department."

The productivity concept as developed by Taylor, Gilbreth, and Miles has multiple dimensions and attributes.  Important of them are quality and human comfort, safety and health.

Introduction to the Principles of Teaching - Edward L. Thorndike - 1906

I am writing about teaching and learning in Industrial Engineering blog as Industrial engineers have to train operators in new methods. They have to provide knowledge or information also about the new method to the operators and develop positive attitudes and feelings in them regarding the new methods. Basic principles of teaching and learning are applicable to training process also.


 The Aims of Education.—Education as a whole should make human beings wish each other well, should increase the sum of human energy and happiness and decrease the sum of discomfort of the human beings that are or will be, and should foster the higher, impersonal pleasures. These aims of education in general—good will to men, useful and happy lives, and noble enjoyment —are the ultimate aims of school education in particular. 

Its proximate aims are to give boys and girls health in body and mind, information about the world of nature and men, worthy interests in knowledge and action, a multitude of habits of thought, feeling and behavior and ideals of efficiency, honor, duty, love and service. The special proximate aims of the first six years of school life are commonly taken to be to give physical training and protection against disease; knowledge of the simple facts of nature and human life; the ability to gain knowledge and pleasure through reading and to express ideas and feelings through spoken and written language, music and other arts; interests in the concrete life of the world; habits of intelligent curiosity, purposive thinking, modesty, obedience, honesty, helpfulness, affection, courage and justice; and the ideals proper to childhood. 

The special proximate aims of school life from twelve to eighteen are commonly taken to be physical health and skill; knowledge of the simpler general laws of nature and human life and of the opinions of the wisest and best; more effective use of the expressive arts; interests in the arts and sciences, and in human life both as directly experienced and as portrayed in literature; powers of self-control, accuracy, steadiness and logical thought, technical and executive abilities, cooperation and leadership; habits of self-restraint, honor, courage, justice, sympathy and reverence; and the ideals proper to youth.


The schools must prepare for efficiency in the serious business of life as well as for the refined enjoyment of its leisure.


The Special Problem of the Teacher.— It is the problem of the higher authorities of the schools to decide what the schools shall try to achieve and to arrange plans for school work which will attain the desired ends. Having decided what changes are to be made they entrust to the teachers the work of making them. The special problem of the teacher is to make these changes as economically and as surely as is possible under the conditions of school life. His is the task of giving certain information, forming certain habits, increasing certain powers, arousing certain interests and inspiring certain ideals. 

The principles of teaching may mean the general principles applicable to the formation of all habits or the highly specialized rules of procedure for forming the habit of correct use of shall and will; they include the laws valid for the acquisition of any knowledge and the discussion of the particular difficulties in teaching the spelling of to, two and too. But the problem is always fundamentally the same:— Given these children to be changed and this change to be made, how shall I proceed? Given this material for education and this aim of education, what means and methods shall I use?


The sciences of biology, especially human physiology and hygiene, give the laws of changes in bodily nature. The science of psychology gives the laws of changes in intellect and character.

TAYLOR, F. W., "A Piece-Rate System, Being a Step Toward Partial Solution of the Labor Problem,"
Transactions of the American Society of Mechanical Engineers 16, 856-903, 1895

A PIECE-RATE SYSTEM: BEING A STEP TOWARD PARTIAL SOLUTION OF THE LABOR PROBLEM.

BY FRED W. TAYLOR.

The ordinary piece-work system involves a permanent antagonism between employers and men, and a certainty of punishment for each workman who reaches a high rate of efficiency. The demoralizing effect of this system is most serious. Under it, even the best workmen are forced continually to act the part of hypocrites, to hold their own in the struggle against the encroachments of their employers.

The system introduced by the writer, however, is directly the opposite, both in theory and in its results. It makes each workman’s interests the same as that of his employer, pays a premium for high efficiency, and soon convinces each man that it is for his permanent advantage to turn out each day the best quality and maximum quantity of work.

The writer has endeavored in the following pages to describe the system of management introduced by him in the works of the Midvale Steel Company, of Philadelphia, which has been employed by them during the past ten years with the most satisfactory results.

The system consists of three principal elements :

( i ) An elementary rate-fixing department.

( 2 ) The differential rate system of piece-work.

( 3 ) What he believes to be the best method of managing men who work by the day.




Elementary rate-fixing differs from other methods of making piece-work prices in that a careful study is made of the time required to do each of the many elementary operations into which the manufacturing of an establishment may be analyzed or divided. These elementary operations are then classified, recorded, and indexed, and when a piece-work price is wanted for work the job is first divided into its elementary operations, the time required to do each elementary operation is found from the records, and the total time for the job is summed up from these data. While this method seems complicated at the first glance, it is, in fact, far simpler and more effective than the old method of recording the time required to do whole jobs of work, and then, after looking over the records of similar jobs, guessing at the time required for any new piece of work.

The differential rate system of piece-work consists, briefly, in offering two different rates for the same job, a high price per piece in case the work is finished in the shortest possible time and in perfect condition, and a low price if it takes a longer time to do the job, or if there are any imperfections in the work. (The high rate should be such that the workman can earn more per day than is usually paid in similar establishments.) This is directly the opposite of the ordinary plan of piece-work in which the wages of the workmen are reduced when they increase their productivity.

The system by which the writer proposes managing the men who are on day-work consists in paying men and not positions. Each man’s wages, as far as possible, are fixed according to the skill and energy with which he performs his work, and not according to the position which he fills. Every endeavor is made to stimulate each man’s personal ambition. This involves keeping systematic and careful records of the performance of each man, as to his punctuality, attendance, integrity, rapidity, skill, and accuracy, and a readjustment from time to time of the wages paid him, in accordance with this record.

The advantages of this system of management are :

First. That the manufactures are produced cheaper under it, while at the same time the workmen earn
higher wages than are usually paid.

Second . Since the rate-fixing is done from accurate knowledge instead of more or less by guess-work, the motive for holding back on work, or “ soldiering ”, and endeavoring to deceive the employers as to the time required to do work, is entirely removed, and with it the greatest cause for hard feelings and war between the management and the men.

Third. Since the basis from which piece-work as well as day rates are fixed is that of exact observation, instead of being founded upon accident or deception, as is too frequently the case under ordinary systems, the men are treated with greater uniformity and justice, and respond by doing more and better work.

Fourth, It is for the common interest of both the management and the men to cooperate in every way, so as to turn out each day the maximum quantity and best quality of work.

Fifth. The system is rapid, while other systems are slow, in attaining the maximum productivity of each machine and man ; and when this maximum is once reached, it is automatically maintained by the differential rate.

Sixth. It automatically selects and attracts the best men for each class of work, and it develops many first-class men who would otherwise remain slow or inaccurate, while at the same time it discourages and sifts out men who are incurably lazy or inferior.

Finally. One of the chief advantages derived from the above effects of the system is, that it promotes a most friendly feeling between the men and their employers, and so renders labor unions and strikes unnecessary.

There has never been a strike under the differential rate system of piece-work, although it has been in operation for the past ten years in the steel business, which has been during this period more subject to strikes and labor troubles than almost any other industry. In describing the above system of management the writer has been obliged to refer to other piece-work methods, and to indicate briefly what he believes to be their shortcomings.


1. Capital demands fully twice the return for money placed in manufacturing enterprises that it does for real estate or transportation ventures. And this probably represents the difference in the risk between these classes of investments.

2. Among the risks of a manufacturing business, by far the greatest is that of bad management ; and of the three managing departments, the commercial, the financiering, and the productive, the latter, in most cases, receives the least attention from those that have invested their money in the business, and contains the greatest elements of risk. This risk arises not so much from the evident mismanagement, which plainly discloses itself through occasional strikes and similar troubles, as from the daily more insidious and fatal failure on the part of the superintendents to secure anything even approaching the maximum work from their men and machines.

3. It is not unusual for the manager of a manufacturing business to go most minutely into every detail of the buying and selling and financiering, and arrange every element of these branches in the most systematic manner and according to principles that have been carefully planned to insure the business against almost any contingency which may' arise, while the manufacturing is turned over to a superintendent or foreman, with little or no restrictions as to the principles and methods which
he is to pursue, either in the management of his men or the care of the company’s plant.

4. Such managers belong distinctly to the old school of manufacturers ; and among them are to be found, in spite of their lack of system, many of the best and most successful men of the country. They believe in men, not in methods, in the management of their shops ; and what they would call system in the office and sales departments, would be called red tape by them in the factory. Through their keen insight and knowledge of character they are able to select and train good superintendents, who in turn secure good workmen; and frequently the business prospers under this system (or rather, lack of system) for a term of years.

5. The modem manufacturer, however, seeks not only to secure the best superintendents and workmen, but to surround each department of his manufacture with the most carefully woven network of system and method, which should render the business, for a considerable period at least, independent of the loss of any one man, and frequently of any combination of men.

6. It is the lack of this system and method which, in the judgment of the writer, constitutes the greatest risk in manufacturing; placing, as it frequently does, the success of the business at the hazard of the health or whims of a few employees.

7. Even after fully realizing the importance of adopting the best possible system and methods of management for securing a proper return from employees and as an insurance against strikes and the carelessness and laziness of men, there are difficulties in the problem of selecting methods of management which shall be adequate to the purpose, and yet be free from red tape, and inexpensive.

8. The literature on the subject is meagre, especially that which comes from men of practical experience and observation. And the problem is usually solved, after but little investigation, by the adoption of the system with which the managers are most familiar, or by taking a system which has worked well in similar lines of manufacture.

9. Now, among the methods of management in common use there is certainly a great choice ; and before describing the “differential rate” system it is desirable to briefly consider the more important of the other methods.

10. The simplest of all systems is the “day-work” plan, in which the employees are divided into certain classes, and a standard rate of wages is paid to each class of men ; the laborers all receiving one rate of pay, the machinists all another rate, and the engineers all another, etc. The men are paid according to the position which they fill, and not according to their individual character, energy, skill, and reliability.

11. The effect of this system is distinctly demoralizing and levelling; even the ambitious men soon conclude that since there is no profit to them in working hard, the best thing for them to do is to work just as little as they can and still keep their position. And under these conditions the invariable tendency is to drag them all down even below the level of the medium.

12. The proper and legitimate answer to this herding of men together into classes, regardless of personal character and performance, is the formation of the labor union, and the strike, either to increase the rate of pay and improve conditions of employment, or to resist the lowering of wages and other encroachments by the part of employers.

13. The necessity for the labor union, however, disappears when men are paid, and not positions ; that is, when the employers take pains to study the character and performance of each of their employees and pay them accordingly, when accurate records are kept of each man’s attendance, punctuality, the amount and quality of work done by him, and his attitude towards his employers and fellow-workmen.

As soon as the men recognize that they have free scope for the exercise of their proper ambition, that as they work harder and better their wages are from time to time increased, and that they are given a better class of work to do— when they recognize this, the best of them have no use for the labor union.

14. Every manufacturer must from necessity employ a certain amount of day-labor which cannot come under the piece-work system ; and yet how few employers are willing to go to the trouble and expense of the slight organization necessary to handle their men in this way ? How few of them realize that, by the employment of an extra clerk and foreman, and a simple system of labor returns, to record the performance and readjust the wages of their men so as to stimulate their personal ambition, the output of a gang of twenty or thirty men can be readily doubled in many cases, and at a comparatively slight increase of wages per capita!

15. The clerk in the factory is the particular horror of the old-style manufacturer. He realizes the expense each time that he looks at him, and fails to see any adequate return ; yet by the plan here described the clerk becomes one of the most valuable agents of the company.

Production Industrial Engineering - Six Sigma Case Studies in Machining Processes


Six sigma method attempts to reduce defects and improve the process output parameters while achieving the lowest variance. In the direction of defect reduction, six sigma study helps in moving towards zero defects. Six sigma method has to be used by industrial engineers in all process improvement studies using process charts.

Six Sigma Simple Explanation


DMAIC Method

Six sigma method determines the best factor level combination that gives the optimal output with the least variation.

Hence the starting point is the output variable whose measurement or measure is to be optimized and its variability made minimum. The next step is the identification of factors that have an effect on the output variable of interest. The third step is determining the possible levels of each factor that can be employed.

With this as the input information, Taguchi method of experimental design is used to determine number of experiments to be done. The experiments are done and results are statistically analyzed to get the factor level combination that gives the best output variable with the least variance.

Further improvement of the system can be done by engineering modifications that  permit more levels of the factors or introduction some completely new factor that can five better performance of the output variable. Industrial engineers have to look for engineering improvements on a continuous basis. Industrial engineering is primarily engineering improvement.

Optimization of Process Parameters based on Surface Roughness and Cutting Force in MQL Turning of AISI 4340 using Nano Fluid


The aim of this research work is focused on optimization of process parameters under Minimum Quantity Lubrication (MQL) using nano fluid in turning of AISI 4340. A study of effect of process parameters in turning of AISI 4340  on the cutting force generated and machined surface roughness is carried out. In the experiment conducted, five values of feed rate, three values of depth of cut, two values of cutting speed and tool nose radius respectively, are used. The test pieces were turned on a CNC lathe machine.  

From result analysis, it was found that, feed rate played a major role in producing lower surface roughness followed by depth of cut whereas cutting speed has least significance in producing lower surface roughness.  It was observed that MQL with nano fluid (MWCNT) showed lowest surface roughness as compared to conventional flood system. Thus, with proper selection of process parameters under MQL mode with nano coolant, it is possible to achieve good surface roughness, reduce tool wear while maintaining the cutting forces and temperatures at reasonable levels.

Ready for Six Sigma

To upgrade machining process capability, Prof. Jerard is conducting research on the process capability of machine tools.

 Currently, CNC manufacturers are providing  two indicators of precision: positioning accuracy and repeatability. But what is the standard deviation of a machine tool?  For example, a machine tool with a standard deviation of 0.002 in. can achieve a six sigma quality level  only when the tolerance band of a part is 0.022 in. If the standard deviation doubles to 0.004 in.,  jump from six sigma quality level to 66,800 defects per million (three sigma).

If machine tools have be made with smaller standard deviations,  error sources such as machine axis squareness, encoder inaccuracy, tool and workpiece deflection, thermal expansion, tool runout and tool wear etc. have to be understood and their impact on standard deviation has to be found. Many of these factors change with time, environmental conditions and usage.

Henry Gantt - Biography and Contribution - Industrial Engineering

Henry Laurence Gantt, A.B., M.E. (May 20, 1861 – November 23, 1919) was an American mechanical and industrial engineering.


Gantt was born in Calvert County, Maryland. He graduated from McDonogh School in 1878 and from Johns Hopkins University in 1880. He taught at the McDonogh School for three years. He received a Masters of Engineering degree from the Stevens Institute of Technology in New Jersey.


In 1884, he joined as a Mechanical Engineer with Pool and Hunt of Baltimore. In 1887 became an assistant to Frederick W. Taylor in applying industrial engineering (scientific management) principles to the work at Midvale Steel and Bethlehem Steel, working there with Taylor until 1893. In his later career as a management systems  consultant, he designed the 'task and bonus' system of wage payment and additional measurement methods for worker efficiency and productivity.

Best Wishes #NITIE #IndustrialEngineering
National Institute of Industrial Engineering, Mumbai.
Diamond Jubilee Celebrations 2023 (1963-2023).



Industries are relying on Industrial Engineering techniques  to improve productivity  to deal with competition. Continuous improvement for higher productivity of manufacturing and operations to increase the value of a product and service is the key role of Industrial Engineer.

Some of the sharpest minds graduate from the National Institute of Industrial Engineering (NITIE, Mumbai), as skilled professionals that improve industrial efficiency and productivity.

Summer Internship Projects(SIP) of NITIE students are mainly focused on cost reduction through waste elimination, quality management, Inventory control, warehouse productivity, Material Requirement Planning, productivity improvement through automation, Lean thinking, Logistic, Supply Chain Network, and Industry 4.0 technologies (viz. IT, Machine Learning, Artificial intelligence, Blockchain, Data Analytics, etc.) to name a few.

Benefits Provided by NITIE Students During Summer Internship Projects(SIP) - Illustrations.

Increased warehouse productivity by 15% amounting to an annual saving of $65,000.

A NITIE intern worked to automate the process of scheduling more than twenty thousand parts that are procured regularly for more than 300 variants of various commercial vehicles.

After As-Is analysis of the Inbound Logistics Network, the project recommended changing the current route for importing, shifting from LCL (Less than Container Load) to FCL (Full Container Load) for certain commodities and checking the feasibility of reusable packaging for imports, etc. with a cost savings of approx. ₹ͅ 1,00,000 per container.

The internship project recommended factory consolidation from 10 sites to 7 sites with an addition of 2 new cross-docking hubs giving a potential annual savings of 15.8 crore INR,  and a payback period of three years.

An award-winning internship demonstrated the application of IE tools like Clustering, Load-Distance analysis, MILP in reducing the number of warehouses from 35 to 27 with minimization of total transportation cost by 8%; decrease in average primary & secondary transportation distance by 14% & 6% respectively with improved service level and simplified tracking and monitoring of primary and secondary supply routes using an MIS Dashboard.

40 Years with NITIE: 1977 - 2017 - Narayana Rao Kambhampati


5.15 am 26 May 2017 (Indian Standard Time)

Yesterday only I returned from a trip to Pittsburgh USA. I reached home by 10.30 pm on 25 May 2017. I started from Pittsburgh at 5.50 am on 24 May 2017 (US Eastern Time) and travelled to Chicago first and from there took the Delhi direct flight operated by Air India.







On 23 May 2017, I made a presentation on Principles of Industrial Engineering in the Annual Conference of Institute of Industrial and Systems Engineers (IISE).  Industrial engineering as an academic discipline started in 1907 at Penn State University. A book with the title "Principles of Industrial Engineering" was authored by C.B. Going. But principles of industrial engineering were not declared so far in the industrial engineering literature. My deep thinking on industrial engineering that spanned the period 1994 to 2016, suddenly gave me the idea on 4 July 2016. I made my blog post on that day on the topic. I took one more year to go to the world's premier platform and make a presentation on the issue. This completes my 40 years association with NITIE (National Institute of Industrial Engineering, Mumbai, India). I joined NITIE in 1977 and started learning industrial engineering in more earnestness. We had industrial engineering as a subject in our undergraduate programme at JNTU College of Engineering, Kakinada. But more serious and focused learning started in 1977. So in forty years, I moved from learning to telling. On 23 May 2017, I was explaining about industrial engineering to consultants from Maynard group (now with Accenture) and to a group of students from Penn State. A man from India, going and explaining industrial engineering to pioneers of industrial engineering in the birth state of industrial engineering. I thought I shall write about my journey during this 40 year period. Thus begins this writing adventure.

I present below the video made by my daughter on the presentation. My daughter's friend took photographs of the slides with her mobile phone. I shall add them also later.


Principles of Industrial Engineering Presented by Professor K.V.S.S. Narayana Rao (Author of this blog) on 23 May 2017 at the Annual Conference of Institute of Industrial and Systems Engineers in Pittsburgh, USA.  Industrial Engineering is a management subject or discipline with Engineering as the foundation. Its primary application area is engineering systems. Its augmented application area is any system.  INDUSTRIAL ENGINEERING IS SYSTEM EFFICIENCY ENGINEERING AND HUMAN EFFORT ENGINEERING (Definition by Narayana Rao - Published in Udyog Pragati, Jounral of NITIE in 2006)

Principles of Industrial Engineering


An explanation says principles are scientific theories or cause and effect relationships. They are of permanent nature until revised due to empirical studies and identification of new facts.

Methods are general approaches that use the scientific principle or principles for beneficial use. They are also of permanent nature.

Tools are contemporaneous ways of implementing methods.

Basic Principles of Industrial Engineering - Narayana Rao


1. Develop science for each element of a man - machine system's work related to efficiency and productivity.
2. Engineer methods, processes and operations to use the laws related to the work of machines, man, materials and other resources.
3. Select or assign workmen based on predefined aptitudes for various types of man - machine work.
4. Train workmen, supervisors, and engineers in the new methods.
5. Incorporate suggestions of operators, supervisors and engineers in the methods redesign on a continuous basis.
6. Plan and manage productivity at system level.

(The principles were developed on 4 June 2016 at Kakinada where I went for a holiday to celebrate my  birthday and with mother, brothers and sisters and other relatives). The principles were  developed by Narayana Rao based on principles of scientific management by F.W. Taylor)

Principles and Practices of Productivity Management - Narayana Rao - 2021

 

The development of science related to productivity improvement, and modifying engineering and management systems to utilize productivity science in engineering activities and organizations are the major activities of industrial engineers. We can say productivity science, productivity engineering and productivity management are the major components of industrial engineering. - Narayana Rao.

Principles of Industrial Engineering, Proceedings of the 2017 Industrial and Systems Engineering Conference, K. Coperich, E. Cudney, H. Nembhard, eds., pp. 890-895.

Industrial Engineering Philosophy, https://nraoiekc.blogspot.com/2021/04/industrial-engineering-philosophy.html


Productivity Management- Principle of Industrial Engineering

Every industrial engineer is a productivity manager. 

He has to plan for productivity and achieve productivity improvement year after year.

As a part of productivity management, he has to assess management actions of the organization for effect on productivity and has to recommend changes if they have an adverse effect on productivity or if there is scope for increasing productivity by modifying them.

Principles of Industrial Engineering, Proceedings of the 2017 Industrial and Systems Engineering Conference, K. Coperich, E. Cudney, H. Nembhard, eds., pp. 890-895.

In this article, I am trying to develop principles of productivity management. In this endeavor, principles of management provide the basic direction. In addition, the related principles are also to be included appropriately.

Productivity science is the foudation for productivity planning.

Productivity Management Related Principles from Literature


Harrington Emerson - Twelve Principles of Efficiency - Productivity Management


1. Clearly defined ideals.
2. Common sense
3. Competent counsel
4. Discipline
5. The fair deal
6. Reliable, immediate and adequate records
7. Despatching
8. Standards and schedules
9. Standardized conditions
10. Standardized operations
11. Written standard-practice instructions
12. Efficiency-reward

1. Clearly defined ideals.

Every organization must have defined ideals that align its employees and guide their behavior. We are today using the terms, objectives, goal, mission, purpose, value etc. for the term ideals used by Emerson.

2. Common sense

Emerson talks of higher level understanding of persons in higher levels of management to promote efficiency.

3. Competent counsel

Efficiency improvement is a specialized knowledge area, and companies have to appoint specialists to develop the efficiency develop function in the organization and take their help in announcing programs and practices.

4. Discipline

The organization has to make plans and run its operations according to the plan.

5. The fair deal

In the organization, every body must perceive fairness in dealings.


Reliable records are required for good plans including good efficiency plans.


What is to be done at each machine needs to be determined by planning department and is to be communicate to the workman.


There needs to be a schedule planned for each machine and operator in the organization based on customer deliveries promised and the associated criteria. Standard times for doing various operations are to be developed to help in developing schedules.


In the organization all facilities and environmental conditions have to be planned to meet specified objectives. A planned facility is termed standard facility. 


The movements of machine components, the motions of operators, the transport and handling of materials are to be planned to meet specified objectives.


Standardized conditions and standardized operations are communicated to concerned persons in the organization through standard practice instructions. The efficiency expected will come about only when all activities are performed as per standard practice instructions.


Efficiency improvement has to result in benefit to all involved to sustain it. Employees have to receive efficiency reward as the efficiency in organization goes and the financial benefits are realized.


Principles of Productivity Growth


Given by Prof Paul Mali in the year 1978 in Improving Total Productivity, John Wiley & Sons, New York.

1. Principles of Ratio Time Measurement


Productivity is more likely to improve when expected results are measured and made greater in the same time frame that expected resources are measured and made less.

2. Principles of Shared Gain

Productivity increases rapidly when its expected benefits are shared with those who will produce it.

3. Principle of Expectancy Alignment

The greater the alignment of employee expectancies (needs) with organizational objectives (targets), the greater the motivation to accomplish both.

4. Principle of Worker Accountability

Accountability for productivity is more likely to happen when employees understand, participate in, and are held responsible for productivity objectives, measurement, and evaluation.

5. Principles of Focus

The greater the focus toward productivity objectives on a time scale, the greater the likelihood of achieving these objectives.

6. Principle of Creating Potential Productivity

Productivity gains are more likely to be achieved from situations where the potential for productivity gain is created.

7. Principle of Continuance

Productivity tends to continue when achieving an objective does not incapacitate or destroy any of the factors which produced it.

8. Principle of  Work Justice

Productivity is more likely to continue when employees are given equal pay for equal work; when employers are given equal work for equal pay.

9. Principle of  Elasticity

Productivity tends to increase when the same amount of work is achieved in a shorter period of time.

10. Principle of  Resource Priority

Productivity increases when objectives for productivity set the priorities for resource allocation.



Principles of Productivity Management - Narayana Rao



Principles of Productivity Planning


Related to Purpose and nature

Principle of contribution to objectives
          Every plan created by productivity managers at various levels has to contribute positively toward the productivity improvement of the enterprise. 

Principle of efficiency of plans
          Efficiency is measured by the contribution of the plan to objectives of the enterprise minus the costs and unsought for consequences in formulating and implementing the plan. Productivity plans and projects have to satisfy the principle of efficiency. They have to provide the ROI specified by the organization.

Principle of primacy of planning
          Planning is the primary prerequisite for all other functions of management. Every action of the productivity manager must be based on a plan. 

Principles Applicable to Structure of plans

Principle of planning premises
          If more people in an organization use common and consistent planning premises, the enterprise planning will be more coordinated. Productivity managers have to provide various facts related to productivity within the organization, productivity related ideas and products available in the market place, and facts related to productivity in competitor organizations. Wide dissemination of this information will make productivity activity in the organization more coordinated.

Principle of policy framework
          If more policies, appropriate to the organization, are expressed in clear terms and form and if managers understand them, the plans of the enterprise will be more consistent. Productivity policies have to be expressed in terms and form desired by managers, supervisors, and operators.

Principle of timing
          If plans are structured to provide a network of derivatives plans in sequence, there will be more effectiveness in attainment of enterprise objectives. Productivity plans have to developed for various time periods and various sections or departments within the organization.


Principles Applicable to Process of Planning

Principle of alternatives
          Select the plan which is the most effective and the most efficient to the attainment of a desired goal. Development of alternatives is an important step of planning. Alternative productivity plans have to developed and choice has to be made.

Principle of limiting factor
          Consider limiting factor in generating alternatives and selection from alternatives. What is the limiting factor for productivity improvement? Plan around it.

The commitment Principle
          Planning can cover a period over which commitment of resources can be clearly visualized. Productivity plans approved and released must have the provision for resources approved by the budget committee of the organization.

The flexibility Principle
          Building flexibility in planning is beneficial and profitable flexibility alternatives have to be included in plans.  Plans must have flexible features. For illustration, if internal resources cannot be provided, external consultants can be employed to support productivity improvement.

The Principle of navigational change
          Productivity managers  need to periodically check events of the plan and redraw plans to maintain the move toward a desired goal.

Principle of competitive strategies
          In a competitive arena, it is important to choose plans in the light of what competitor will or will not do and navigate based on what competitors are doing or not doing. Productivity achievements of competitors have to be monitored and creative efforts and learning efforts are to be initiated to understand and improve.



Principles of Organizing


Principles in Relation to Purpose

Principle of unity of objectives
          An organization structure is effective if it as a whole, and every part of it, make possible accomplishment of individuals in contributing toward the attainment of enterprise objectives. Productivity management as a function, has to ensure that every individual is part of productivity maintenance and improvement activity.

Principle of efficiency
          An organization or organization structure is efficient if it is structured to make possible accomplishment of enterprise objectives by people with minimum unsought consequences or costs. Productivity managers have to foresee the effects of productivity engineering changes. The issues bothering the persons who have to implement them have to be addressed.     
      



Principles in Departmentizing Activities


Principle of division of work


        The better an organization structure reflects a classification of the tasks and activities required for achievement of objectives and assists their coordination through creating a system of interrelated roles; and the more these roles are designed to fit the capabilities and motivations of people available to fill them, the more effective and efficient an organization structure will be. Productivity is everybody's activity in an organization. There are productivity management staff, but their direction is to everybody in the organization through formal as well as informal methods.



Principle of functional definition


        The more a position or a department has clear definition of results expected, activities to be undertaken, organization authority delegated, and authority and informational relationships with other positions, the more adequately individual responsible can contribute toward accomplishing enterprise objectives. The results expected from each productivity manager has to be clearly specified.



Principles in the Process of organizing


Principle of balance

   The application of principles or techniques must be balanced in the light of the over-all effectiveness of the structure in meeting enterprise objectives.

Principle of flexibility
    The task of managers is to provide for attaining objectives in the face of changing environments. The more provisions are made for building organization flexibility, the more adequately organization structure can fulfill its purpose.

Principle of leadership facilitation
    The more an organization structure an authority delegations within it make possible for various managers to design and maintain an environment for performance, the more it will facilitate leadership abilities of managers.


Staffing Principles



Related to the Purpose of Staffing



Principle of staffing objectives

    

The positions provided by the organization structure must be staffed with personnel able and willing to carry out the assigned functions. Productivity department has to be staffed with persons with education in productivity improvement, in industrial engineering in engineering organizations and enthusiasm for the task.


The process of staffing



Principle of managerial appraisal


Performance must be appraised against the management action required by superiors and against the standard of adherence in practice to managerial principles. Productivity managers need to have targets for productivity improvement and they need to be appraised for results and processes used.

Principle of management development
    The objective of management development is to strengthen existing managers. The most effective means of developing managers is to have the task performed primarily by a manager's superior.

Principle of universal development

The enterprise can tolerate only those managers who are interested in their continuous development. Productivity have to develop their knowledge of technology on a continuous basis.

Principles of Directing

Related to the Purpose of Directing

Principle of harmony of objectives

Effective directing depends on the extent to which individual objectives in cooperative activity are harmonized with group objectives. Productivity as an organizational objective has to be harmonized with individual's objectives. Taylor said productivity has to offer higher income to operators and higher profits to the organization simultaneously. It is genius of Taylor, that he proposed the principle through implementation of the principle first in a machine shop and then in other departments and areas.


Principles  Applicable to Process of directing

Principle of unity of command
The more completely an individual has a reporting relationship to a single superior, the less the problem of conflict in instructions and the greater the feeling of personal responsibility for results. The instructions to the operator are mainly given through instruction cards who are given to the operator by his foremen. The foreman is facilitated in this task by production planning departments of the shop.

Principle of direct supervision

Effective direction requires that management supplement objective methods of supervision with direct personal contact.

Principle of supervisory techniques
    Since people, tasks, and organizational environment vary, techniques of supervision will be most effective if appropriately varied.

Principles of Delegation


Principle of functional delegation
The more a position or department has clear definitions of results expected, activities to be undertaken, organization authority delegated, and authority and informational relationships with other positions, the more adequately individuals responsible can contribute toward accomplishing enterprise objectives.

Principle of delegation by results expected
 The authority delegated to an individual managers should be adequate to assure his ability to accomplish the results expected of him.

Principle of absoluteness of responsibility
No superior can escape, through delegation, responsibility for the activities of subordinates, for it is he who delegated authority and assigned duties. If the expected productivity does not materialize, the productivity manager cannot get away from his responsibility.

Principle of parity of authority and responsibility
The authority delegated has to be consistent with the responsibility assigned to a subordinate.




Principles of Control


Related to the purpose of control

Principle of assurance of objective
The task of control is to assure accomplishment of objectives by detecting potential or actual deviation from plans early enough to permit effective corrective action. Productivity targets must be capable of being measured periodically.

Principle of efficiency of controls
The more control approaches and techniques detect and illuminate the causes of potential or actual deviations from plans with the minimum of costs or other unsought consequences, the more efficient these controls will be. Productivity controls have to be cost effective and should not cause dissatisfaction in operators.

Principle of control responsibility
The primary responsibility for the exercise of control rests in the manager charged with the execution of plans.

Principle of direct control
The higher the quality of managers and their subordinates, the less will be the need for indirect controls.
(The principle may termed as principle of reduced controls. A superior can spend less time in control activities if he has more higher quality managers and their subordinates in his department.)

Productivity education and training are important. Productivity managers themselves have to demonstrate productivity in certain select activities done by operators.

Principles related to Structure of control

Principle of reflection of plans
The more controls are designed to deal with and reflect the specific nature and structure of plans, the more effective they will serve the interests of the enterprises and its managers.

Principle of organizational suitability
The more controls are designed to reflect the place in the organization structure where responsibility for action lies, the more they will facilitate correction of deviation of events from plans.

Principle of individuality of controls
Controls have to be consistent with the position, operational responsibility, competence, and needs of the individuals who have to interpret the control measures and exercise control. 

Process of control

Principle of standards
Effective control requires objective, accurate, and suitable controls.

Principle of critical-point control
Effective control requires attention to those factors critical to appraising performance against an individual plan.

The exception Principle
The more a manager concentrates his control on exceptions, the more efficient will be the results of this control.

Principle of flexibility of controls
If controls are to remain effective despite failure or unforeseen changes in plans, flexibility is required in the design of controls.

Principle of action
Principle of Action
Control is justified only if indicated or experienced deviations from plans are corrected through appropriate planning, organizing, staffing and directing.

Measure only those which are monitored by the concerned and corrected. Don't make people fill forms for no purpose.
