Subject Areas in Industrial Engineering - A New Scheme



I am currently teaching an advanced course in industrial engineering with the following subject scheme.

Subject Areas in Industrial Engineering - A New Scheme


Industrial engineering principles
Product industrial engineering
Process industrial engineering
   - Technical process industrial engineering
   - Management process industrial engineering
Industrial engineering optimization
Industrial engineering technometrics (Application of statistics in industrial engineering projects and practice).
Industrial engineering economics
Human effort industrial engineering
Measurements in industrial engineering
Productivity management

The course is going smoothly. We are studying the basic content on each topic for two hours based on the notes prepared by our first year masters students based on their class lecture, discussion and study. Then we are examining some recent research papers.

A presentation was done to the prospective masters students based on this scheme and they appreciated the presentation.

What is missing in the scheme is productivity science or industrial engineering science. Under this head we need to discuss scientific method and some of the experiments, research and theory building done in the industrial engineering field. In the textbooks of sociology and psychology, scientific enquiry is described as one chapter.

Industrial engineering optimization (IEO)

Product and process alternative concepts developed by industrial engineers initially start as concepts, go through technical feasibility and commercial feasibility stages. Optimization using mathematical and operations research methods becomes an important stage in industrial engineering studies and projects. The optimization done in IE projects is one component of industrial engineering optimization. Independently, IEs may examine systems for lack of optimality and suggest or do optimization. This aspect also comes under I.E.O.

Industrial engineering technometrics (Application of statistics in industrial engineering projects and practice).

Sampling increases productivity of activities. So industrial engineering field suggests and utilizes sampling at appropriate stages in the production process. Industrial engineers use experiments in developing science as well as engineering solutions. Use of statistics by industrial engineers is convered in industrial engineering technometrics.

Industrial engineering economics


Use of engineering economic analysis in IE studies is explained in Industrial engineering economics.

Human effort industrial engineering


Human effort is redesigned by F.W. Taylor, Frank Gilbreth, R.L. Barnes and H.B. Maynard to realise productivity improvements. Motion study and work measurement are two important methods of IE in this area. The concern of IE regarding fatigue and comfort of operators is now supported by ergonomics discipline in providing science of occupational impact on the workmen. The musculoskeletal disorders suffered by the workers are prevented by early analyses of ergonomists. IEs take the scientific theories developed by ergonomics and engineer human effort.

Measurements in industrial engineering

Work measurement, Productivity measurement and Cost measurement are the three important measurement subjects for industrial engineers.

Process Industrial Engineering



Process Improvement - Gilbreths' View


Frank Gilbreth developed process analysis and improvement also along with motion study. In 1921, he presented a paper in ASME, on process charts. Lilian Gilbreth was a coauthor of this paper.

https://engineering.purdue.edu/IE/GilbrethLibrary/gilbrethproject/processcharts.pdf


At the end of the paper, the conclusion made is as follows:

The procedure for making, examining and improving a process is, therefore, preferably as follows:

a.  Examine process and record with rough notes and stereoscopic diapositives the existing process in detail.

b. Have draftsman copy rough notes in form for blueprinting, photographic projection and exhibition to executives and others.

c. Show the diapositives with stereoscope and lantern slides of process charts in executives' theater to executives and workers.

d. Improve present methods by the use of —
1 Suggestion system
2 Written description of new methods or 'write-ups," "manuals," ''codes," ''written systems," as they are variously called
3 Standards
4 Standing orders
5 Motion study
6 Micromotion studies and chronocyclegraphs for obtaining and recording the One Best Way to do Work.

e. Make process chart of the process as finally adopted as a base for still further and cumulative improvement.


We see in the method described above the method study steps of record, and examine. The practice of involving the workers in analyzing the process chart which was later popularized by Alan Mogensen is also present in the method suggested by Gilbreth to improve a process.  Motion study as a later step in the process analysis method, which was emphasized by H.B. Maynard as part of the operation analysis proposed by him is also visible in the procedure described by Gilbreths.

H.B. Maynard proposed "Operation Analysis" for process improvement.

So, we can see the methods engineering and methods study which became popular subsequently were futher development of Gilbreth's process improvement procedure only.


Process Engineering


Process engineering focuses on the design, operation, control, optimization and Intensification of chemical, physical, and biological processes. Process engineering encompasses a vast range of industries, such as chemical, petrochemical, agriculture, mineral processing, advanced material, food, pharmaceutical, software development and biotechnological industries.

Process Industrial Engineering


Process engineering is an established term in engineering. Hence process industrial engineering, which represents the redesign of processes by industrial engineers to improve productivity is an appropriate term.


Methods Engineering, Operations Analysis, Method Study and Motion Study are various methods or procedures of process industrial engineering.

The process industrial engineering has to develop analysis and improvement of technical elements of a process in more detail to make industrial engineering an engineering based activity to increase productivity in engineering organizations, departments and activities.

Process industrial engineering also includes improvement of related management activities. F.W. Taylor was a pioneer in introducing many changes in management practices to improve productivity. Industrial engineering adopted the same objective. So within process industrial subject area comes the function of management process industrial engineering.

Water Productivity - Why Waste Water? - Eliminate The Water Waste





"Why Waste Water?" is the theme of World Water Day 2017.
http://www.worldwaterday.org/theme/
http://www.unwater.org/news-events/news-details/en/c/468902/

The theme is relevant to industrial engineers? What is the water consumption in industry? Is the consumption efficient? Are industrial engineers doing analysis of water consumption. Resource use analysis or productivity analysis is the first part of IE study. The second part of coming out with more productive processes.

Industry uses 19% of the global consumption of water.
Iron & Steel industry uses 95,000 to 150,000 liters of water for producing a tonne of steel.

The uses of water

Only 1% of water used by humans (compared to the global sum of all withdrawals) is for drinking, washing and cooking. An additional 10% is calculated for all other domestic uses (toilet flushing etc). Industry uses 19% and the rest, a massive 70%, is used by agriculture for irrigation, drawing water from rivers, lakes and underground water strata.

The  concept  of  water  productivity  (WP) in Agriculture


The  concept  of  water  productivity  (WP)  is  offered  by  Molden  et  al. (2003)  as  a  robust
measure of the ability of agricultural systems to convert water into food. While it has been
used  principally  to  evaluate  the  function  of  irrigation  systems  as  the  amount  of  ‘crop  per
drop’, it seems reasonable to extend the concept toinclude other types of livelihood support,
such as mixed cropping, pasture, fisheries or forests.

Opportunities for Improvement (eds J.W. Kijne, R. Barker and D. Molden)

The Water Productivity term plays a crucial role in modern agriculture which aims to
increase yield production per unit of water used, both under rainfed and irrigated conditions.
This can be achieved either by 1)increasing the marketable yield of the crops for each unit of
water transpired, 2) reducing the outflows/ losses, or 3) enhancing the effective use of
rainfall, of the water stored in the soil, and of the marginal quality water.

A systematic and quantitative approach to improve water use efficiency in agriculture
Theodore C. Hsiao, Pasquale Steduto, Elias Fereres Pages 209-231

Causes of the differences in efficiency in each step, going from water delivery to soil water
extraction, transpiration, photosynthesis, and conversion to crop biomass and yield, and to animal product are discussed in the paper. Based on an equation quantifying the impact of changes in efficiency of component steps on the overall efficiency, it is concluded that generally, it is
more effective to make modest improvements in as many steps as possible than to concentrate efforts to improve one or two steps.



Beyond irrigation efficiency
Marvin E. Jensen Pages 233-245

This paper describes how efficient management of water for irrigation requires a full understanding of water balance for the field, irrigation project, or river basin under consideration. Development of the classic term irrigation efficiency is summarized along with recent modifications such as effective irrigation efficiency which reflects the efficiency of the system in terms of the amount of water effectively consumed by the system, taking into account outflows water as not wholly “wasted” or “lost” from river basins and that can be recovered and made available for use in the context of the water balance of the river basin. This makes it possible to develop accounting procedures for water use, or water accounting based on the water balance approach for a water basin and analyzing the uses, depletion, and productivity of water.

Economics, adoption determinants, and impacts of micro-irrigation technologies: empirical results from India

R. E. Namara, R. K. Nagar, B. Upadhyay Pages 283-297

The study by Namara et al. (analyses of micro-irrigation adoption and impacts in selected localities of Maharashtra and Gujarat states in India) indicates that micro-irrigation technologies result in significant productivity improvement and hence economic gain over the traditional method of surface irrigation.  The most important
determinants of micro-irrigation adoption identified by the study include access to groundwater, the prevailing cropping pattern (proportion of staples vs. high value crops), level of education, availability of cash, the social stratum of the household, and the wealth or poverty status of the
farmer. The majority of the current adopters of low-cost micro-irrigation systems are the richer section of the farming population. Thus, reducing the cost alone is not yet effective to improve
the outreach of micro-irrigation technologies.

An Explanation of Industrial Engineering - 19 March 2017


Came across this explanation of industrial engineering today in  MM Industrial Spectrum Special Issue of 2015.  The title of the article is Machinery and Industrial Engineering.         http://www.mmspektrum.com/

The ambition of industrial engineering is to prepare specialists who are able to search and
implement system solutions of manufacturing and supply problems, to increase efficiency
of enterprise processes, who are able to plan and project manufacturing processes and
systems, to provide their high productivity and reliability and to eliminate all sorts of losses
and costs which do not create value added.


Characteristics
Industrial engineering is a multidisciplinary branch combining knowledge of the engineering  field and  experience  of enterprise management.

This branch should use all available sources inside the company as effectively as possible, which are e. g. information itself, financial sources, human work,  knowledge  and  abilities  of  people etc. Therefore, its main task is to rationalize, optimize and improve manufacturing and
non  manufacturing  processes.

Changes are applied at practice through projects which shall eliminate all losses and to provide the highest possible productivity.

R.L. Barnes, in his book Motion and Time Study, in the chapter 3 History of Motion and Time Study had written that it is generally agreed that Time Study had its beginning in the machine shop of the Midvale Steel Company in 1881 originated by F.W. Taylor. That led me to search the internet for this fact and made me come across some interesting articles about Taylor.

Taylor described his time study experience in Piece Rate Paper.

Frederick Taylor, late in the year of 1874, when he was eighteen, seized upon the chance to learn, in the shop of a small Philadelphia pump-manufacturing company whose proprietors were acquainted with his family, the trades of the pattern- maker and the machinist.

THIS Philadelphia concern in whose employ Fred Taylor learned his trades was known as the Enterprise Hydraulic Works, and the firm that owned it while he was there was first Ferrell & Jones and then Ferrell & Muckle. The works were situated in Race Street, down near the Schuylkill River.

In 1881, when the Navy's Ordnance Bureau invited fifteen American steel manufacturers to submit proposals for forgings for six-inch all-steel guns, Midvale was the only plant that could undertake the workj for it alone had developed a complete system of experimentation and of records.

To Brinley must be awarded the main credit, not only for these triumphs in the technic of steel making, but also for the organization of the working force. By 1882, when he left Midvale, and was succeeded as superintendent by Davenport, he had put practically every operation in the works, down to the handling of coal, upon a piece-work basis.


In speaking of Taylor's work at Midvale, Carl Barth says: " He constantly investigated tools and other small appliances that gave minor trouble or fell short of giving entire satisfaction, and in discovering the cause of their shortcomings, was able to effect highly-desirable improvements. Many of
these improvements probably could easily have been made by anyone else who had taken the trouble Taylor did to investigate. The basis of it lay in the fact that it was Taylor's genius to recognize the importance of trifles."


Still, he exerted himself on these trips pretty strenuously also. "As we travelled almost every day," Taylor wrote in 1910, " we were obliged to carry very heavy loads in pack baskets on
our backs. My load averaged over eighty pounds, and in some cases was as high as 125 pounds and I many times carried this load more than eight miles per day over the rough trails in the woods." This despite the fact that he " weighed then only 145 pounds."



The engineering type of man [says J. E. Otterson ] works for the solution of a single technical or engineering problem and is concerned with the determination of the solution rather than the applica-
tion of that solution to practical activities. The true type has the capacity to concentrate continuously on a single problem until the solution has been reached. He is interested in the determination of
cause and effect and of the laws that govern phenomena. He is disposed to be logical, analytical, studious, synthetical and to have an investigating turn of mind. The predominating characteristic that
distinguishes him from the executive is his ability to concentrate on one problem to the exclusion of others for a protracted period, to become absorbed in that problem and to free his mind of the cares
of other problems. He does not submit readily to the routine performance of a given amount of work. He deals with laws and abstract facts. He works from text books and original sources of
information. Such men are Edison, Steinmetz, the Wright Brothers, Curtiss, Bell, Pupine, Fessenden, Browning. These men are the extreme of the engineering type; they have enormous imagination,
initiative, constructive powers. Mr. Taylor was in reality an engineer rather than an executive. He applied his wonderful inventive genius to the invention of management methods.

The executive type takes the conclusions of the engineer and the laws developed by the engineer and applies them to the multitude of practical problems that come before him. His chief characteristic
is that he works with a multitude of constantly changing problems at one time. He concentrates on one problem after another in rapid succession. In many instances he has not the time to obtain all of
the facts and he must arrive at a conclusion or make a decision based upon partial knowledge. He must rapidly assimilate available facts and fill in what is lacking from the ripeness of his own experience, frequently calling on his powers of judgment, and even of intuition. He is a man of action, boldness, ingenuity, force, determination, aggressiveness, courage, decision; he is possessed with the desire to get things done, impatient of delay. He works from a handbook, a news-
paper, or nothing at all. Such men are Schwab, Goethals, Pershing, Farrell, Hindenburg, Hoover.

Even to this day many engineers consider their work done when they have designed and built and demonstrated the possibilities of a piece of apparatus. They seem to feel that the efficient operation of it is not in their province. Mr. Taylor felt otherwise. To him, perfection in design was worthless without efficiency in operation, and at an early date he turned his attention to the efficient utilization of human effort.

DEVELOPING HIS
SYSTEM AT MIDVALE

http://archive.org/stream/frederickwtaylor01copl/frederickwtaylor01copl_djvu.txt


 Taylor was a man of intellect. His purpose to get output had its roots in his desire to make the most economical use of his shop's facilities. From the start he was a true engineer in that he was a true
economist,^ with all the economist's hatred of waste and his instinct for conservation.

He himself came to define the problem of the machine shop as that of " removing metal from forgings and castings in the quickest time." " It sounds like the simplest of propositions
that herein is involved the whole economy of such a shop.


He found that his master task or problem of getting metal out in the quickest time naturally divided itself into two principal sets of detail problems j the one having to do with the mechanics of the shop's equipment, and the other with the workers' operation of that equipment.

Right at the outset of his career as an industrial economist he was confronted by the deeply significant fact (which his fellow engineers as a class and industrial folk in general were very slow
in getting a grip on) that as there is no machinery so automatic that it does not have to be cared for and have its work supplied to it by human beings, all other industrial problems are swallowed up in the problem of human relations.


Taylor set out accurately to determine {i.e., on a basis of fact) what his men ought to be able to do with their equipment and materials. It was the course that he himself came to describe as
that of " gathering in on the part of those on the management's side of all the great mass of traditional knowledge which in the past has been in the heads of the workmen and in the physical skill and knack of the workman," and of " recording it, tabulating it, and, in many cases, finally reducing it to
laws, rules, and even to mathematical formulae."

Here, then, aside from his action in clearly defining his  master problem as foreman, was his beginning with the scientific method in connection with management — the beginning
which, because it was the logical one and his qualities were what they were, made it inevitable that he should extend the scientific method to all of the elements of management and so bring into existence all of the phenomena of Scientific Management or of that coherent and logical whole destined to become known as the Taylor System.


Taylor, started in the i88o's, led the work of scientifically studying the speeds at which the ma-
chines should be run in the shop, thereby bringing about, as one feature of his work — and it was a feature that deeply wounded the pride of the English — the development of excellence, as by shaping and heat treatment, in metal-cutting tools themselves.

Mention has been made of the fact that Sellers as early as 1876 attempted to have the cutting tools used in his plant issued to the workmen ready ground to shapes and angles adopted as standard after some investigating. This may be taken as illustrating that all along Taylor had contemporaries
who approached and grappled with problems of management in a truly scientific spirit. However, it also illustrates that the work of these other men was unsystematic and confined to a single element or only a few of the elements of management} so that, as Taylor came to express it, there was " great unevenness or lack of uniformity shown, even in our best run works, in the development of the several elements which together constitute what is called the management."




Taylor was the only one who started at the beginning both in his thinking and in his action j which
is to say that he was the only one who, seeing that it is the task of management to bring about the most economical use of labor and equipment entering into production, and seeing also that to fulfill this task the management must determine what the output of the labor aided by the equipment should be, resolutely set out to do this and stuck to it.


This man for two years and a half, I think, spent his entire time in analyzing the motions of the workmen in the machine shop in relation to all the machine work going on in the shop — all the operations, for example, which were performed while putting work into and taking work out from the machines were analyzed and timed. I refer to the details of all such motions as are repeated over and
over again in machine shops. I dare say you gentlemen realize that while the actual work done in the machine shops of this country is infinite in its variety, and that while there are millions and millions of different operations that take place, yet these millions of complicated or composite operations can be analyzed intelligently and readily resolved into a comparatively small number of simple elementary operations, each of which is repeated over and over again in every machine shop. As a sample of these elementary operations which occur in all machine shops, I would cite picking up a bolt and clamp and putting the bolt head into the slot of a machine, then placing a distance piece under the back end of the clamp and tightening down the bolt. Now, this is one of the series of simple operations that take place in every machine shop hundreds of times a day. It is clear that a series of motions such as this can be analyzed, and the best method of making each of these motions can be found out, and then a time study can be made to determine the exact time which a man should take for each job when he does his work right, without any hurry and yet who does not waste time. This was the general line of one of the investigations which we started at that time.

Time study was begun in the machine shop of the Midvale Steel Company in, 1881, and was used during the next two years sufficiently to prove its success. In 1883, Mr. Emlen Hare Miller was
employed to devote his whole time to " time study," and he worked steadily at this job for two years, using blanks similar to that shown in Par. 367 of " Shop Management." He was the first man to
make " time study " his profession.

" Time study," as its name implies, involves a careful study of the time in which work ought to be done. In but very few cases is it the time in which the work actually was done.

The Midvale Steel Works started the " profession of time study."

Time study " consists of two broad divisions, first, analytical work, and second, constructive work.

The analytical work of time study is as follows:

a. Divide the work of a man performing any job into simple elementary movements.
b. Pick out all useless movements and discard them.
c. Study, one after another, just how each of several skilled workmen makes each elementary movement, and with the aid of a stop watch select the quickest and best method of making each elementary movement known in the trade.
d. Describe, record and index each elementary movement, with its proper time, so that it can be quickly found.
e. Study and record the percentage which must be added to the actual working time of a good workman to cover unavoidable delays, interruptions, and minor accidents, etc.
f. Study and record the percentage which must be added to cover the newness of a good workmen to a job, the first few times that he does it. (This percentage is quite large on jobs made up of a large number of different elements composing a long sequence infrequently repeated. This factor grows smaller, however, as the work consists of a smaller number of different elements in a sequence that is more frequently repeated.)
g Study and record the percentage of time that must be allowed for rest, and the intervals at which the rest must be taken, in order to offset physical fatigue.

The constructive work of time study is as follows:

h Add together into various groups such combinations of elementary movements as are frequently used in the same sequence in the trade, and record and index these groups so that
they can be readily found.
i. From these several records, it is comparatively easy to select the proper series of motions which should be used by a workman in making any particular article, and by summing the
times of these movements, and adding proper percentage allowances, to find the proper time for doing almost any class of work.
j. The analysis of a piece of work into its elements almost always reveals the fact that many of the conditions surrounding and accompanying the work are defective; for instance, that improper tools are used, that the machines used in connection with it need perfecting, that the sanitary conditions
are bad, etc. And knowledge so obtained leads frequently to constructive work of a high order, to the standardization of tools and conditions, to the invention of superior methods and machines.

It is unusual to make a study such as this of the elementary movements of the workmen in a trade. The instances in which this has been done are still rare. Most of the men who have made what they
call " time study " have been contented with getting the gross time of a whole cycle of operations necessary to do a particular piece of work, and at best they have thrown out the time when the workman was idle, or evidently purposely going slow.

When he was at Phillips Exeter, he was profoundly impressed by his observation of the way
his professor of mathematics, " Bull " Wentworth, had timed the work of the students in solving various problems, and so was able to give out standard lessons in the sense that he knew
how much time the average boy would take to do them. All the indications are that to the extent Taylor was indebted to him.

Before long he established what one of his associates calls the " unalterable rule that all time study for rate setting must be done not merely with the knowledge but with the co-operation of the worker."


Somewhere along about 1881 it clearly was presented to him that his problem of getting metal cut in the quickest time involved studying both what his men could do and what the machines could do. Hence his two types of experiments and it is highly probable, by the way, that his machine experiments, or those which constituted a " study of the art of cutting metals," were to a large extent inspired by what he observed while developing " accurate motion and time study of men."


The most important discovery of immediate value that Taylor made in the early stage of his experiments on cutting metals  was that " a heavy stream of water poured directly upon the chip at the
point where it is being removed from the steel forging by the tool would permit an increase in cutting speed, and therefore in the amount of work done, of from thirty to forty per cent."



The discovery of Taylor was used by Midvale in a new shop,  which was opened in 1884. In this new shop, each machine was " set in a wrought iron pan in which was collected the water (supersaturated with carbonate of soda to prevent rusting) which was thrown in a heavy stream upon the
tool for the purpose of cooling it. The water from each of these pans was carried through suitable drain pipes beneath the floor to a central well from which it was pumped to an overhead tank from which a system of supply pipes led to each machine." And Taylor added : " Up to that time, so far as
the writer knows, the use of water for cooling tools was confined to small cans or tanks from which only a minute stream was allowed to trickle upon the tool and the work, more for the purpose of obtaining a water finish on the work than with the object of cooling the toolj and, in fact, these small streams of water are utterly inadequate for the latter purpose."




It interesting to note this comment of Taylor. In spite of the fact that the shops of the Midvale Steel Works until recently [1906] have been open to the public since 1884, no other shop was similarly fitted up [with water supply for the machines] until that of the Bethlehem Steel Company in 1899,
with the exception of a small steel works which was an off-shoot in personnel from the Midvale Steel Company."



One of the other great opportunities which the building of the new shop gave him was that of beginning the experiments with belting that, extending over a period of nine years, furnished him with material for a paper which, presented to the A.S.M.E. in 1893, drew from Henry R. Towne, who himself had experimented with belting, this comment:

The present paper is modestly entitled " Notes on Belting," but could be more fittingly described as a treatise on the practical use of belts. Its thirty-four pages contain more new and useful informa-
tion than is found in any other paper that has come to my knowledge.


In his paper On the Art of Cutting Metals (page 32), Taylor listed his variables as follows: "
(a) the quality of the metal which is to be cut}
(b) the diameter of the workj
(c) the depth of the cut;
(d) the thick-ness of the shaving;
(e) the elasticity of the work and of the tool;
(f) the shape or contour of the cutting edge of the tool, together with its clearance
and lip angles;
(g) the chemical composition of the steel from which the tool is made, and the heat treatment of the tool;
(h) whether a copious stream of water or other cooling medium is used on the tool;
(j) the duration of the cut, i.e., the time which a tool must last under pressure of the shaving without
being reground;
(k) the pressure of the chip or shaving upon the tool;
(1) the changes of speed and feed possible in the lathe;
(m) the pulling and feeding power of the lathe."

Barth, who completed these metal-cutting experiments, has made an improved statement of the variables.


Taylor pursued his metal-cutting investigation long after he left Midvale over a period of a quarter of a century. Not until 1906 did he publish anything about it. However, his high-speed steel, which was one of the by-products of this investigation, was exhibited at the Paris Exposition of 1900.


I am well within the limit, gentlemen, in saying [he testified in 1912] that not one machine in twenty in the average shop in this country is properly speeded.


Our experiments have been of two kinds: first, the reduction of the control and operation of machines from rule of thumb to science, and, second, the examination and standardization of human actions
and work with relation both to maximum efficiency and maximum speed.

Next study all the elements as they effect the speed and output, whether they are connected with the machine alone or with the man and the machine combined; then find the one or more elements which
limit the speed of output; centre on the most important, and correct them one after another. This generally involves a combination of study of the man with the machine and involves in many
cases minute time observations with the stop watch.


His time study and his metal-cutting investigation were indeed closely connected and interwoven j having for their common purpose the cutting down of time to the minimum consistent with the doing of good work. In like manner his belting experiments, which were an offshoot of his metal-cutting investigation, had mainly for their purpose the saving of time through the avoidance of delays and interruptions.

Incidentally we can see this purpose as the general cause of the outpouring of his ingenuity in mechanical invention. His great steam-hammer was designed to work faster than any other thing of its kind. He built a new chimney on top of an old one to save " a loss of at least one or two months in
time." And here is the machine-tool table he invented early at Midvale, the table being the part of the machine on which work is place to be operated on. It usually takes much time to set the work on the table and secure it by clamping, and Taylor just could not stand the spectacle of the machine standing
idle while this was being done. So what he invented was a " false " table, or one that was separable from the machine j this, of course, permitting new work to be made entirely or nearly ready on a table while the machine continued busy. Then his study of cutting tools led him to invent a new tool
holder further to expedite the work. This, roughly described, enabled a tool to be held in various positions to correspond to various surfaces, and thus made it possible for one tool to take the place of several of different shapes.






He hastened the establishment among tools of a beautiful order. Not only a place for everything and everything in its place, but also everything in proper variety, suffident quantity, and the pink o£ condition. And withal a beautiful economy of storage space and facility of finding just what was wanted.


Another high development Taylor brought about at Midvale was his system of oiling machines. This device for maintaining things in standard condition created no end of amusement among Taylor's fellow officers, and the wonder of it still is talked about. All we can do here is to indicate its
general nature.

To begin with, he had a man go over every machine and the moving parts connected with it and chalk every oil hole and every surface that required oiling. Then he had another man cover the same ground to make sure that nothing had escaped the first. This done, he had a high-grade mechanic study the best order in which holes and surfaces should be oiled, and these places then were consecutively numbered by stamping.

For the oil holes he had made two sets of wooden plugs, one set with round heads and the other with square, and each set was numbered to correspond to the numbers of the oil holes. While one set was in the oil holes, the other set was kept in a box bored with holes to correspond to the oil holes.
In like manner he had made for the surfaces to be oiled two sets of small hooks, one with round and the other with square tags.

In the morning, the operator of a machine found the oil holes fitted with square-headed plugs, and at the surfaces to be oiled hung the hooks with the square tags. Before starting his machine he was required to replace the " square " objects with the " round " ones, and as he did this to oil the
hole or surface} and at noon, when another oiling was called for, he was required to replace the " round " plugs and hooks with the " square." The object, of course, was to make him give attention to each and every hole and surface, and do this in the proper order j and at any time it could be seen whether all his " square " or " round " plugs and hooks were in place as might be called for. Incidentally the plugs, which were cylindrical and made a neat fit in the holes, kept dust from getting in and cutting the bearings.

Lists were made out of all the oil holes and surfaces to be oiled} these stating to what parts of the machines the holes conducted the oil, and the kind of oil to be used in each case. Duplicates of these lists were filed in the office j and here we can see an early development of the principle of reducing
all recurrent procedure to standard practice and recording it. The ordinary way is to leave such procedure entirely to some individual, who in the course of time may work out for it a pretty good method. All of this knowledge, however, he carries in his head} so that if he falls ill, the procedure suffers, and if he quits the business, some one else must work it out all over again. Taylor not only required the management to determine right at the start the best method, but by his records he made the business independent of the comings and goings of individuals, and his records served as insurance against mistakes, failures of memory, and human fallibility in general.

 Looking at it from this angle, we see that Taylor assumes the aspect simply of a manager of such thoroughness and force that he leaped from a quarter to a half century ahead of the crowd of managers, and did more than any other one individual to wake management up and blaze a trail for it to follow.


The term general manager indeed implies one having an outlook upon all the steps in the accomplishment of an organization's task.


The shop, and indeed the whole works, should be managed, not by the manager, superintendent, or foreman, but by the planning department. The daily routine of running the entire works should be car-
ried on by the various functional elements of this department, so that, in theory at least, the works could run smoothly even if the manager, superintendent and their assistants outside the planning room were all to be away for a month at a time.


Proper extra pay for the extra effort called for by a scientifically set task will induce the worker to make the extra effort continuously.

It undoubtedly was because of this as well as of the high wages he paid that Taylor never again had any trouble with working people after his early experience at Midvale.




Says H. L. Gantt in Industrial Leadership : " The authority to issue an order involves the respon-
sibility to see that it is properly executed. The system of management which we advocate is based on this principle, which eliminates bluff as a feature of management, for a man can only assume the responsibility for doing a thing properly when he not only knows how to do it, but can also teach somebody else to do it." It should not be difficult for anyone to understand why working people, apart from any question of wages, found it a satisfaction to work for men who could show them as well as tell them, and who incidentally assumed the responsibility for the implements and all the conditions upon which the fulfillment of the tasks depended.


There also was the fact that through his development of standard practice for the care of machinery
and belting and his instruction-card and tickler system, he had cut down the repair force of the works about a third.




Three years later, when he became a consulting engineer, he apparently foresaw that unless he had an impartial critic of the efficiency of his methods in the form of a proper cost-keeping system, he
would be at a disadvantage in dealing with the opposition that his experience had taught him would be sure to arise wherever he tried to introduce his methods. Thus his approach to the scientific study of accounting was mainly from the particular angle of cost accounting. And to say that when he turned his attention to this subject there was no general recognition of the importance of accurately determining, on a basis of ascertained and recorded fact, the group and unit costs of products is to put it mildly — how mildly will be appreciated when it is pointed out that as late as the year 1921 the
Federal Trade Commission reported that about ninety per cent of industrial and commercial firms did not know what their costs were.


Mr. Towne said among other things:

To ensure the best resuhs, the organization of productive labor must be directed and controlled by persons having not only good executive ability, and possessing the practical familiarity of a mechanic or engineer with the goods produced and the processes employed, but having also, and equally, a practical knowledge of how to observe, record, analyze, and compare essential facts in relation to wages, supplies, expense accounts, and all else that enters into or affects the economy of production and the cost of the product.


The fact that Taylor called his paper of 1895 simply A Piece-Rate System, with the cautious subtitle A Step Toward Partial Solution of the Labor Problem, signifies not merely that he yet was unconscious that involved in his work was the development of a comprehensive system and that he himself was deeply interested in the " labor end."


Taylor said in the address he made in Cleveland just before his death:

I have before me something which has been gathering in for about fourteen years, the time or motion study of the machine shop. It will take probably four or five years more before the first book will be
ready to publish on that subject. There is a collection of sixty or seventy thousand elements affecting machine shop work. After a few years — say three, four or five years more — some one will be ready to publish the first book giving the laws of the movements of men in the machine shop — all the laws, not only a few of them. Let me predict, gentlemen, just as sure as the sun shines that is going to come in every trade. Why? Because it pays, and for no other reason. Any device which results in an increased output is bound to come in spite of all opposition; whether we want it or not, it comes automatically.

In Taylor's lifetime these studies resulted in the publication of two books: Concrete Plain and Reinforced (1905), and Concrete Costs (1912).

    Scientific Management - Basis for Industrial Engineering


    Basic Principles of Industrial Engineering


    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, install various modifications related to the machines that include productivity improvement devices and ensure that the expected productivity is realized.
    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 (During Birthday break of 2016 - 30 June 2016 to 7 July 2016).

    The principles were developed by Narayana Rao based on principles of scientific management by F.W. Taylor)

    Principles of Scientific Management


    The managers following scientific management thought do the following things.

    First. They develop a science for each element of a man's work, which replaces the old rule-of.-thumb method.

    Second. They scientifically select and then train, teach, and develop the workman, whereas in the past he chose his own work and trained himself as best he could.

    Third. They heartily cooperate with the men so as to insure all of the work being done in accordance with the principles of the science which has been developed.

    Fourth. There is an almost equal division of the work and the responsibility between the management and the workmen. The management take over all work for which they are better fitted than the workmen, while in the past almost all of the work and the greater part of the responsibility were thrown upon the men.

    Method Study - ILO Book Description


    Work Study Focus is Human Effort

    Work study is only motion and time study. It does not deal with technical aspects directly. Subjects that deal with improvements in technical aspects directly are needed in industrial engineering so that it contributes in a significant way to productivity improvement of engineering systems.
    Work Study - Important Issues to Notice
    http://nraoiekc.blogspot.com/2017/03/work-study-important-issues-to-notice.html




    Method study is the systematic recording and critical examination of existing and proposed ways of doing work, as a means of developing and applying easier and more effective methods and reducing costs.

    The term "method study" is being increasingly used in place of "motion study", although the latter was intended by its inventor, Frank Gilbreth, to cover almost exactly the same field.

    Industrial Engineering Terminology, published by the American Society of Mechanical Engineers, gives separate definitions for "method study" and "motion study", the latter being confined to hand and eye movements at the workplace. However, "motion study" is used in most United
    States textbooks with the same meaning as "method study". Method study as a term is not popular in USA. But methods design as a term was used by some authors.


    The objects of method study are

    The (productivity) improvement of processes and procedures.

    The improvement of factory, shop and workplace layout and of the design of plant and equipment (at the operation stage).

    The development of a better physical working environment.

    Economy in human effort and the reduction of unnecessary fatigue.

    Improvement in the use of materials, machines and manpower.


    METHOD STUDY - BASIC PROCEDURE


    SELECT the work to be studied.
    RECORD all the relevant facts about the present method by direct observation.
    EXAMINE those facts critically and in ordered sequence, using the techniques best suited to the purpose.
    DEVELOP the most practical, economic and effective method,having due regard to all contingent circumstances.
    DEFINE the new method so that it can always be identified.
    INSTALL that method as standard practice.
    MAINTAIN that standard practice by regular routine checks.


    SELECTING THE WORK TO BE STUDIED




    A process has to be selected to do method study investigation based oncertain factors that indicate that the job is priority in terms of benefits that will be realized. These are-

    Economic considerations.
    Technical considerations.
    Human reactions.

    Economic considerations.

    Obvious early choices are

    • "bottlenecks" which are limiting the production
    • movements of material over long distances between shops, or operations involving a great deal of manpower and equipment;
    • operations involving repetitive work using a great deal of labour and liable to run for a long time.


    Technical considerations.

    Are technical experts available to participate in the studies?

    Human reactions.

    Avoid jobs where human resistance is present.

    Select the job most likely to have the greatest over-all effect on the productivity of the enterprise as a whole.

    RECORDING THE FACTS


    The most commonly used of these recording techniques are charts and diagrams. There are charts indicating sequence and charts indicating time scale. Diagrams are used to record movements in a layout. Diagrams supplement charts.

    In the charts called process charts five different activities are represented.

    OPERATION     O
    Inspection    []
    Transportation
    Temporary Delay
    Permanent Delay


    OPERATION Indicates the main steps in a process, method or procedure.
    Usually the part, material or product concerned is modified or changed during the operation.

    INSPECTION Indicates an inspection for quality and/or a check for quantity.

    TRANSPORT Indicates the movement of workers, materials or equipment from place to place.

    TEMPORARY STORAGE OR DELAY Indicates a delay in the sequence of events: for example,
    work waiting between consecutive operations, or any object laid aside temporarily without record until required.

    PERMANENT STORAGE Indicates a controlled storage in which material is received into or issued from a stores under some form of authorisation; or an item is retained for reference purposes.

    The Outline Process Chart

    A "bird's-eye" view of a whole process or activity can be obtained by using an outline process chart.

    An outline process chart is a process chart giving an over-all picture by recording in sequence only the main operations and inspections.

    The time being taken for each step, if it is observed during the study is also added.

    The outline process chart is intended to provide a first "bird's-eye" view of the activities involved. The work study man will understand the operations and inspections being carried out in the process. The chart may be used for the purpose of eliminating unnecessary operations or combining those that could be done together (It is to be noted that technical persons may be required to give the opinion or to answer the questions posted by the work study analyst).
