July First Week - Industrial Engineering Knowledge Revision





Scientific Management of Taylor


Taylor's book is a must reading for industrial engineers. The book emphasizes the development of scientific laws relating to use of machines, tools, related resources and men. This is development of science. Once science is developed, industrial engineers use that science to develop productive machines, productivity improvement devices and methods and that improve productivity.  Taylor also examines some management methods that are sources for low productivity. He suggests management methods that improve productivity. Then Taylor, discusses issues relating to implementing productivity improvement methods. Industrial engineers have no other comparable book on philosophy in their discipline. Hence it has to be read and reread till a new book is authored by a modern day Taylor by incorporating all that has happened in the discipline over the last 100 to 120 years.

Physical infrastructure electronic devices that are able to sense, generate, and transmit data have been around for nearly 50 years. In 1968 Schneider Electric invented the first Programmable Logic Controller (PLC). But the change now in 2015 is the fact that  the cost of IP enablement is now so low and therefore all sorts of devices can be connected to internet to participate in the more open IP-style network and transmit data and receive instructions form various computers anywhere in the world.

Thus IoT allows plants to now monitor new variables that, in the past, were cost prohibitive. Measurement of vibration on machinery and power consumption on all branches of the power system are some examples of how IoT can be cost effectively used in manufacturing and service systems. These lower entry costs are leading to the explosion of the network and generating  a more granular level of data on the existing assets of the firms.

The free-flowing yet structured management of the new data allows managers  within organisations to improve real-time energy and automation tracking in order to cut costs, and operate more safety, reliably, and efficiently.


Leading analysts such as McKinsey & Company are predicting that IoT-enabled business will grow to $10 trillion annually by 2025. IoT will enable higher levels of collaboration and will change the way goods are produced.


Michael Porter is a Harvard economist  expects Internet of Things will deliver "tremendous" efficiency gains.

The Internet of Things will help individual companies to limit the waste factor in global economies in more effective ways. Products which are connected to the web can communicate on their usage patter. This data will be used to schedule maintenance when it's really needed, increasing efficiency. The data will also be used in predictive analytics to reduce failures and improve product design. In sum, all those functionalities will boost the efficiency of production systems.

 It has seemed to me that industrial engineers tend to get smothered in their growing body of techniques and perhaps lose sight of the ends towhichthese techniques should be directed.

If there is anyone theme which has persisted throughout the history of industrial engineering it
is the theme of improving Organization Performance.


There are a number of dimensions along which breadth of industrial engineering practice could be
discussed. I should like to emphasize two dimensions which I shall call the ''Systems Dimension''
and the ''Human Dimension."

I. The Systems Dimension

It seems that there has been one characteristic of traditional industrial engineering practice. Our
approach for many years assumed that we should concentrate on unit operations. Despite admonitions
such as ''look at the preceding and succeeding operation" we have by and large tended to optimize Organizational Performance piece by piece.

 The Systems' concept teaches that the sum of optimal parts is not necessarily equal to an optimal whole. Interactions between units or sub-systems and environmental variables can affect the performance of a system. The effects of this are only obvious when we grasp the system as a total system.

Linear Programming has enabled us to assess the total system of products and machines,
take into account the many inter-relationships of production rates and costs and arrive at a machine
loading program that is within the specified restrictions and is optimal for the total system.
Problems involving a large number of products and machines rapidly tax the capacities of the
most modern computers; however, efficient algorithms are capable of solving problems with as many as 300 products and 18 machines.



The linear programming approach has proven useful not only as a control in assigning products
on a weekly basis, but for long range planning of machine requirements such as;
1. Determining where to place development effort to overcome technological restrictions
which limit the capability of products to be produced on certain machines.
2. Determining the economics of adding additional capacity which is generally
more efficient than present equipment.
3. Determining the best allocation of products for special situations such as extended
periods of machine downtime for maintenance or design changes. This is just one example of work done in the Systems Dimension. Actually, the technology in this area has developed rapidly and can have significant influence on our goal of improving .Organization Performance.


II. The Human Dimension
For the Human Dimension, I'd like to cover two areas; Work Physiology and Organizational
Behavior.  Let's take Work Physiology, first.


A. Work Physiology

In the year 1903, Frederick W. Taylor in his book Shop Management stated, "One of the
most difficult pieces of work which must be faced by the man who is to set the daily tasks is
to decide just how hard it is for him to make the task." (end of quote) This, then, at the
time of Taylor was a decision under conditions of uncertainty and not a measurement. And,
judging by the labor disputes which arise over this question, we seem to be no nearer the point
of being definitive about this question than was Taylor.

What is work effort? Is there an objective way of measuring this effort? Effort can be defined
as an exertion of power or energy and this can be measured and quantified. Energy cannot
be measured by measuring time, but it can be measured by measuring such physiological
phenomena as heart rate, oxygen comsumption and respiratory volume.

The industrial engineer has implied consideration of these physiological phenomena in his concern with fatigue allowances and rest pauses, but even these allowances have generally been based upon time criterion rather than physiological measurements.

Today the industrial engineer has available to him, thru his own and other disciplines, the knowledge
and capability necessary for making quantitative determinations of many of these factors involved
in studying man at work. In the future, to successfully fulfill our role of studying man at work and to integrate him into the organizational system, we need to know the real demands which are being placed upon people. In a sense, we need to know their tolerance to physical and psychological loading.

While as engineers, we wouldn't think of regularly exceeding the design capacity of a production
machine, neither should we exceed the design capacity of the human operator. Knowing this
design capacity has definite humanitarian and economic value.

The optimum work situation is when the work capacities of an individual are compatible
to the work demands of the job. If we underload the individual, the situation is obviously inefficient
and costly. Although it is less obvious, the reverse is also very costly. The resolution of
grievances over work rate, working conditions, and the costs of on-plant medical care, as well
as compensation, do not come cheaply.

While I have earlier singled out the area of effort determination, I don't wish to imply that
this is the only area in which knowledge of human capacities and capabilities is needed. Some other
work situations in which such knowledge is needed are; tasks involving maintenance of a performance level during monitoring and vigilance tasks, frequent decision-making associated with
rapid paced operations, and the integration of an aging industrial population into an increasingly
complex and rapid paced industrial enviornment.

To define and approach these problems requires an understanding and application of physiological
knowledge. engineers. If they are to be solved, we must seek the assistance of other professions
and disciplines. No one discipline is sufficient within itself to bring to bear all of the effort
that is needed. This, then, dictates the need for the team approach. Our work physiology studies at Kodak Park, which started about five years ago, developed from a common need of the Medical Department and the Industrial Engineering Division to better understand the physiological limitations and capabilities of people. The understanding of common problems that has developed between
these two divisions, in itself, almost justifies the effort which has been expended on these
studies. The real reward, of course, is in our growing ability to evaluate and quantify situations
which heretofore, from a job design standpoint, had to remain unknown.

Initially, our investigations were confined solely to the ''effort" or "energy expenditures"
aspect of work. This was natural for several reasons, namely:
1. High effort is more obvious to the observer of the industrial scene and,
therefore, demands more attention.
2. While it is fractionated and scattered, much work has been done and reported by other investigators relative to "'energy expenditure", which is a measure of effort.
3. Instrumentation has been developed such that it is now practical to measure this variable of "energy expenditure" on the industrial scene.
Energy expenditure is measured by the indirect calorimetry method; that is, respiration
and oxygen consumption are the variables which are measured and converted to energy. Combined
with heart rate, these represent the physiological responses which we feel are necessary for accurately assessing high effort industrial jobs.

Physiological measurements in conjunction with time study now provide us with an insight
into industrial job design problems which is not obtainable in any other way. Using criterion
relative to energy expenditure, we can now assess jobs prior to the installation of a new work
standard or job design. We are in a better position to determine in terms of time and energy
what the job requires, the frequency of rest breaks, the necessity of providing auxiliary labor
saving equipment or the need for re-engineering the job completely. In situations where
the manufacturing process is not amenable to change, then the same physiological measurements
help us to select persons with the physical capacity demanded by the process. Most preemployment
medical examinations do not completely provide this information.

This new approach to designing industrial jobs has been successfully employed in many
types of jobs ranging from the handling of containers in a darkroom cold storage area to the
loading of box cars. A most rewarding use of it involved the pre-evaluation of a proposed piece
of production equipment. The work physiology studies indicated that additional materials handling
equipment was necessary if we were to obtain the anticipated increased production. The
nature of this materials handling equipment was such that installation at a later time would have
caused an extensive shutdown with the resultant loss of production.

With the measurement of and utilization of energy expenditure as a factor in job design, we
feel we are just beginning our work physiology studies. Energy expenditure is just one facet of
the problem. Other physiological phenomena of people may be studied so that we can integrate
them into job systems which take advantage of their capabilities and do not aggravate their
limitations. The result will be mutually beneficial to the individual and the company. The
second part of our Human Dimension is Organizational Behavior.


B. Organizational Behavior

I am using this term to refer to the behavior of people in an organizational or industrial setting.
As an area of knowledge, among other things, it refers to the reasons why people work or don't work, decide or don't decide to perform so as to achieve the objectives of their organizations.

If the concept of "Organizational Behavior" seems remote from industrial engineering to you, let me say that an incentive system, or any control system for that matter, is primarily designed to direct and influence the behavior of people towards organizational goals. As industrial engineers we are, it seems, in the business of designing systems to influence, direct and control human behavior, but we've never quite faced up to it in these very words.

The famous Western Electric Hawthorne studies of thirty years ago marked the beginning
of organized research into Organization Behavior. Since that time, studies in industry plus general
behavioral research have yielded information which promises utility to industry.


I think I can summarize the results of this research (and its utility to industrial engineers) this way.

--------------
You industrial engineers profess, in effect, a theory of management - a theory of how to organize men, machines, and materials so as to get the best results. The part of this theory which deals with men assumes that the performance of people will be best under situations where they are told exactly
what to do and how to do it, and are rewarded with money in proportion to performance.
Your way of doing business rests on certain behavioral assumptions.

''To put it another way, you are hipdeep in designing systems for influencing behavior and you make almost no use of the collective scientific information about the behavior of man. The assumptions which support your practice are not all wrong; they are just not complete nor up to
date. You need, first, to realize that you are deeply involved in influencing people's work attitudes, second, that you do this based upon certain assumptions, and third, that there is a good deal of information available which would alter and improve these assumptions."

You might assume that under the proper conditions, they will actually find personal satisfaction in
working towards your objectives.

----------------

In the short time left, I can only outline the manner in which we at Kodak Park are trying to
answer this challenge. In the first place, we have acquainted ourselves with the research
which bears on the problem. We have tried to integrate this to the best of our ability and reduce
it to the probable effect it may have on our practice. The following specifics are indicated:

1. Job Design

Instead of simply designing operations from the point of view of the optimum technical system, we think there are gains to be made in considering the nature of the jobs which people will do.
The usual industrial engineering criteria for job design stress extremes of task specialization. The consequences tend to be meaningless jobs. That is, jobs in which the individual has difficulty
seeing the relationship of his function to a larger whole. A version of what has been called Job Enlargement is called for. This is not just a matter of adding functions to a job, but adding a set of
functions which will comprise a set of activities leading to accomplishment of a visible objective. The activities making up a job should be examined to see if there has been a tendency to
remove the thinking functions and specialize them in other persons. Taken as a whole, we should endeavor to design jobs such that people have a maximum of control of the variables which
lead to end objectives.

2. Goal Orientation - Information Systems

A natural consequence of the over division of labor has been to focus the attention of individuals on very minute goals such as pieces per hour. We believe that industrial engineers should re-examine their approach to the goal setting function which is, after all, what time study has led to all these
years. People, it seems, do not behave on the job as isolated individuals. Many jobs are parts of a system and depend for success upon a high degree of interdependency of people. We are examining the structuring of goals to see what beneficial effect there is in providing the individual a perception
of his contribution to system goals. This takes the form of specifying job goals in terms of end-results and also in terms of the contribution of job level goals to system goals. Individuals are kept informed of system objectives, current progress of the system and any contemplated changes in objectives.
In effect, they are kept "in the know" about objectives and progress of the unit as well as their own job goals. In effect, we are trying to enlarge the focus of the individual relative to end objectives. By giving his more control through Job Design and overall goal orientation, we think his performance
and personal satisfaction will both increase.


III. Compensation or Incentive Systems
For many years, industrial engineering activity has been closely identified with incentives. The classical incentive approach stresses the closest possible relationship between pay and rate-of-output performance. As any of you who have administered an incentive system know, you have to take the bitter with the better. There are a number of practical problems or dysfunctions associated with incentives. I shall not stress these, but will try to describe the more fundamental problems. If we are to believe the results of behavioral research, people work for the satisfaction of a number of human needs. Only some of these can be satisfied by money. The most serious indictment of classical
incentives is that they have pre-occupied us with money to such an extent that we have largely
overlooked other considerations. Such things as achievement, responsibility, recognition and
work, itself, are satisfactions and sources of motivation in themselves. Our problem, here,
is to retain some monetary incentive, some pay/performance relationship, but not to do it
in such a manner that it is seen as the be-all and end-all of motivation. We believe that
closer attention to Job Design and Goal Orientation, previously mentioned, is one way of
providing a basis for satisfaction in the job. There is nothing in motivational research to indicate that relating rewards such as pay to performance is unsound. How this is done seems to be most important, however. We think that money should be looked upon as an after-the-fact reinforcement, not the primary initial motivator of good performance. In contrast to classical wage incentives, which stress close, short term, hour by hour correlation of pay and performance, the shift from "motivator"
to "reinforcement" may be brought about by extending the time over which pay and performance
are related. In addition, by utilizing longer time periods, performance considerations like quality, versatility and dependability can be considered in terms of pay.

We may close by reviewing the official definition of Industrial Engineering as it appears
on the AIIE Journal: "Industrial Engineering is concerned with the design, improvement, and installation of integrated systems of men, materials and equipment; drawing upon specialized knowledge and skill in the mathematical, physical, and social sciences together with the
principles and methods of engineering analysis and design, to specify, predict, and evaluate the results to be obtained from such systems."

If we are to believe this definition as a statement of what industrial engineers do, then we must assume that in our practice we do, indeed, draw upon knowledge from the social sciences. (But industrial engineering has not effectively drawn research conclusions or principles from the social or life sciences) . If we are to be designers of integrated systems of "men, materials and equipment," and if the design activity is to be based upon specialized scientific knowledge, then we had better equip ourselves to do so, (this article specifically focuses on)  the social or life sciences.

An Engineering-Economic Analysis
of Syngas Storage
The authors examined whether an IGCC facility that operates its gasifier continuously but stores the
syngas and produces electricity only when daily prices are high may be more profitable than an
IGCC facility with no syngas storage.
There are currently eight integrated coal gasification / combined cycle electrical turbine (IGCC)
facilities operating worldwide producing about 1.7 GW of electricity from coal or petcoke
feedstock, and in all of these facilities the syngas is used immediately after it is produced. There
are over one hundred coal gasification facilities producing chemical feedstocks, also without
storage. Without storage capabilities, the gasifier must be sized to fit the syngas end-use (such as
a gas turbine or chemicals process) and the operation of the two systems must be coupled.
Stored syngas may be used to produce electricity in gas turbines during periods of peak demand
when produced electricity is most valuable and prices are highest, while operating the gasifier at
the most efficient sustained production rate. Stored syngas may be a means to enhance the
reliability and availability of IGCC power plants, by increasing the availability of syngas during
planned and unplanned outages. Without storage, the coal gasification facility must be sized to
the gas turbine or other facility that uses the gas. Storage allows the two units to be sized and
run separately, thus gaining valuable flexibility. For IGCC designs where the air separation unit
is not fully integrated with the turbine (Farina 1999; Maurstad 2005), adding the capability to
store syngas can allow the gasifier and turbine to be sized and operated independently, thereby
providing valuable flexibility in the way the facility is configured and operated
The goal of this two year research project was to conduct a detailed study of syngas storage
options. The analysts performed an engineering-economic analysis of storage to inform the design of coal
gasification facilities as well as energy policy. The project collected the relevant syngas data
from gasification processes; explored the technical issues of storage such as hydrogen
embrittlement, leakage and energy loss from syngas storage; and performed an engineeringeconomic
analysis of storage options. In a parallel and complementary approach, they analyzed
the benefits and costs of syngas storage options under a variety of scenarios, sampling the
uncertainties in commodity prices, technical options, and regulatory policies.

Industrial engineering is redesign of engineering system both products and production system to make them productive and economical. Industrial engineering improves efficiency and reduces cost of production and products. Reduction in costs permits companies to sell products at lower prices and increase sales. Thus industrial engineering provides growth to companies and thus in aggregate provides growth to economy.


The redesign is done immediately after the original designers come out with the design and also many times later during the operation of the production system or production life cycle of the product.


Industrial engineering methods can be classified in these categories


1. Product Design Efficiency Engineering

2. Methods Efficiency Engineering  - Production Methods Efficiency Engineering, Inspection Methods Efficiency Engineering, Maintenance Methods Efficiency Engineering,  Business Processes Efficiency Engineering, Management Methods Efficiency Engineering

All resources used in methods are analysed for efficient usage.  Man, Material, Money, Management, Motive Power, Machine,

3. Industrial Engineering Optimization -  Engineering system problems are expressed as mathematical functions and maximum or minimum values as appropriate are ascertained to use as design values.

4. Industrial Engineering Statistics - Issues related to variability in engineering systems are decided using statistical methods - Ex. Statistical quality control, Six sigma methodology to improve process capability to determine the target central value and minimise variation of the process.

5. Industrial Engineering Economics - Use of engineering economics methodology to decide the productivity of capital used in engineering systems

6.Human Effort Engineering - Principles of Motion Economy, Motion Study to improve human effort efficiency, Ergonomics, Job Evaluation and Wage Incentives

7. Work Measurement, Cost Measurement, and Productivity Measurement

Principles of Motion Economy - Some More Details - R.M. Barnes


Use of the Human Body

1. The two hands should begin as well as complete their motions at the same time.

2. The two hands should not be idle at the same time except during rest periods.

3. Motions of the arms should be made in opposite and symmetrical directions and should be made simultaneously.

Barnes has written that the three principles can be examined or discussed simultaneously. He gave the example of bolt and washer assembly. In the old method bolt is picked up by the left hand and then a lock washer is picked up by the right hand placed on the bolt. Next, the right hand picks up a steel washer and placed on the bolt. Then a rubber washer is picked up the right hand and placed on the bolt. The completed assembly is disposed of in a container placed at the left side of the operator. As we can see two hands are moving simultaneously. One is holding the bolt and the other hand is doing picking and assembling work. In the revised method, a fixture is made that holds two bolts and has recess. The operator has 7 bins before him. He first pickups a rubber washer from bins numbered one on left and right. Actually the bottom of the bins slope toward the work area at a 30 degree angle so that materials are fed onto the work area by gravity. The operator slides the washers into the recesses of the fixture. Then steel washers are slided. The the lock washer is slided into position. Two bolts are picked and dropped into the fixture. Then both bolts are removed and disposed of in bins placed on the right side as well as left side. In the return motion they pick the new rubber washers.
You can visualize how all three principles are applied in the new design.
See video clip easier way produced by General Motors in 1946 illustrating these principles.
___________

4. Hand and body motions should be confined to the lowest classification with which it is possible to perform the work satisfactorily.

Classification of Hand-motions
1. Finger motions
2. Wrist motions
3. Forearm motions
4. Upper arm motions
5. Shoulder motions (This class of motions results in disturbance of the posture)

Barnes highlighted that in one investigation it was found that finger motions were more fatiguing, less accurate, and slower than motions of the forearm. The evidence points out that th forearm is the most desirable member to use for light work, and that in highly repetitive work,motions about the wrist and elbow are superior to those of the fingers or shoulders.

Bending has physiological cost. A study made by Barnes et al. on picking bricks from a platform 5 inches above the floor and another platform 37 inches above the floor to place them on a bench 33 inches high showed that both energy expenditure and heart beat were high when picking up bricks from 5 inch high platform. These sort of experiments are to be conducted by industrial engineers in their motion studies to improve the comfort and health of operators.

5. Momentum should be employed to assist the worker wherever possible, and it should be reduced to a minimum if it must be overcome by muscular effort.

In certain tasks, it is possible to employ momentum of the hand, the tool or the part being moved to do useful work.  Where a forcible stroke is involved, the motions have to be arranged such that the stroke is delivered with the greatest momentum. In the tasks where the momentum must be overcome by the worker's muscles, momentum must be reduced to a minimum by decreasing the weight of the tools and parts because it causes fatigue.

Barnes quoted Gilbreth's motion study. In laying a brick wall, if the bricks are conveyed from the stock platform to the wall with no stops, the momentum can be made to do valuable work by assisting to shove the joints full of mortar. If instead of being utilized, the momentum must be overcome by the muscles of the bricklayer, fatigue will result. The idea case is to move the brick in a straight path and make the contact with the wall to overcome the momentum.

Barnes quoted another example of candy dipping. He pointed out that  the piece tobe dipped was submerged under the surface of the melted sugar by the right hand at the end of a long return stroke of the hand and the momentum developed in the movement of the hand was employed in doing useful work instead of being dissipated by the muscles of the dipper's arm.

6. Smooth continuous curved motions of the hands are preferable to straight-line motions involving sudden and sharp changes in direction.

Barnes has given the examples of paper holding and dipping of candy to illustrate this point.

7. Ballistic movements are faster, easier, and more accurate than restricted or fixation or controlled movements.

Voluntary movements of the members of the human body may be divided into two general classes or groups: fixation movements and ballistic movements.

In the fixation or controlled movements, opposing groups of muscles are contracted, one group against the other. .

The ballistic movement is a fast, easy motion caused by a single contraction of a positive muscle group with no antagonistic muscle group contracting to oppose it.

The ballistic movement is initiated by an impulse given through the contraction of a muscle, once underway the muscles are relaxed and the course of the movement can not be changed.

The skilled carpenter swinging a hammer in driving a nail illustrates a ballistic movement.

It is not difficult to develop the free, loose, easy movements of the wrist and forearm.



8. Work should be arranged to permit an easy and natural rhythm wherever possible.

Rhythm can refer to the regular repetition of a certain cycle of motions by an individual.
Rhythm which is a proper sequence of motions, assists in making the operation practically an automatic performance - there is no mental effort on the part of the operator.

9. Eye fixations should be as few and as close together as possible.

The work place should be so laid out that the eye fixations are as few and as close together as possible. In one example given in Barnes, the author comments that, had the containers been placed directly in front of the operator, the head movements would have been eliminated entirely and he eye movements would have been greatly reduced.

In another example, Barnes highlights that with practice eye fixations come down and the time required also comes down accordingly. This example is related to the punch-press operation wherein, a part has to be placed in the die using a tweezer. Initially, three eye fixations are used. One for placing the parts in the die, one for taking the part from the left hand with the tweezer and one for taking the part in left hand from the plate having the parts. After 10,000  cycles, only 44 per cent of the time. eye fixation is used pick up the part from the plate having the parts. 56 per cent of the time, the part is being picked up by the left hand without an eye fixation.  The average time for the operation has come down to 0.0258 minutes from 0.0584 minutes. One of the reasons was the decrease in number of eye fixations.

Principles Related to the Work Place


10. There should be a definite and fixed places for all tools and materials.

Definite and fixed places for materials and tools aid the operators in habit formation. This helps in the development of automaticity. It is advantage when operators can perform the operations with the least conscious mental direction. When materials and tools are at fixed places, the hand automatically finds them without support of eyes and the eyes may be kept fixed on the point where the tools and materials are used.

11. Tools, materials, and controls should be located close to the point of use.

For an operators , sitting or standing, the comfortable working place is bounded by lines which are arcs of circles.
The maximum working area for each hand is determined by an arc drawn with a sweep of the hand across the table, with the arm pivoted at the shoulder. In the overlapping area work involving both hands can be done comfortably.

Each hand has its normal working area in the vertical plane as well.

Those tools and parts that must be handled several times during an operation should be located closer to the fixture or working position than tools or parts that are handled but once. For example  if an operation consists of assembling a number of screws into a metal switch plate, the containers for the screws should be placed closer to the fixture than container for the plates as only one plate is to be transported and several screws have to be transported in a cycle.

It is also important to emphasize that parts must be arranged in such a way as to permit the shortest eye movements, the fewest eye fixations, and the best sequence of motions, and to aid the operator in rapidly developing automatic and rhythmic movements.

Interesting example: A radio assembly consists of 260 separate parts/subassemblies. Moving the parts closer by 6 inches saved 34,000 hours per year. which means saving of 17 mandays.

Corollary: The machines, process apparatus, and equipment should be arranged so as to require the least movement on the part of the operator.

When worker operates several machines and when they are located in line along an aise, considerable walking between machines is required. A better arrangement is to have those machines located close together in a group so that the operator can load and unload each of the machines with little or no travel.



12. Gravity feed bins and containers should be used to deliver material close to the point of use.

Bins with sloping bottoms provide the parts at the bottom tray of the bin and operator need not dip into the bin to pick up the part. To provide many different parts, nested bins one above the other are used.
Bins and hopper for process shops - http://www.processsolutions.net/bins.html

13. Drop deliveries should be used wherever possible.

Arrangements are to be done to release the finished units from the position is was completed and deliver them to their destination by gravity.
There is significant amount of time involved in manually disposing the finished items. A study of disposing gauging small pins was conducted in this context. The study involed disposing of the pins into a tote box kept as 3 inches behind a fixture, 10 inches behind a fixture and 20 inches behind a fixture.
The time was least when the pins were tossed into the bin 3 inches near the fixture. The therbligs involved were transport loaded and release load. Eighteen percent more time was used when the bin was at 10 inches and 34 per cent more time was spent when the bin was kept at 20 inches distance.

14. Materials and tools should be located to permit the best sequence of motions.

The material required at the beginning of a task cycle should be place next to the point of release of the finished piece in the preceding task cycle.

In the example of assembly of the bolt and washers (points 1,2 and 3) the rubber washers were in bins located nearest to the chute into which assemblies were disposed in the last motion of the previous cycle.

The time for a motion changes based on the preceding or succeeding motion. For example, the time for the motion transport empty is likely to be longer when it is followed by the motion select than when it is followed a well defined motion such as a grasp of a pre-positioned part.

When the motion transport loaded is follwed by a position motion, it is slowed by the mental preparation for the position.

15. Provisions should be made for adequate conditions for seeing. Good illumination is the first requirement for satisfactory visual perception.

Adequate illumination means:
(1) light of sufficient intensity for the particular task,
(2) light of the proper color and without glare, and
(3) light coming from the right direction.

The visibility of an object is determined by the following variables.

# Brightness of the object
# Its contrast with its background
# The size of the object
# The time available for seeing
# The distance of the object from the eye and
# Other factors such as distractions, fatigue, reaction time, and  glare.

All of these factors must be above a limiting value and then a deficiency in one may be compensated by an augmentation of one or more of the others.

 16. The height of the work place and the chair should preferably arranged so that alternate sitting and standing at work are easily possible.

17. A chair of the type and height to permit good posture should be provided for every worker.
Design of tools and equipment


Principles of Motion Economy As Related to the Design of Tools and Equipment



18. The hands should be relieved of all work that can be done more advantageously by a jig, a fixture, or a foot-operated device.

Barnes has written that foot operated equipment is not utilized adequately in methods and tool design (p.223). He also mentions that one company saved 50 percent time on the operation of soldering a wire to the end of flat metal electric static shield by the use of a foot-operated soldering iron. The brief description of foot operated soldering iron was given in the book by Barnes. 

Procter and Gamble designed and built foot control units which rotate the pipe or tube when welder is cutting and welding pipes.

It is also possible to use two foot pedals to actuate different parts of a jig, fixture, or machine by the operator. This arrangement will be similar to the automobile where there are pedals for accelerator, brake and clutch.


19. Two or more tools should be combined wherever possible.


Develop and use two ended tools. It is usually quicker to turn a small two-ended tool end-for-end that it is to lay one tool down and pick up another.  Tack hammer and tack puller, two-ended wrench, and pencila and erasure are good examples. The designer of telephone handset used this idea only when in one unit he arranged both the transmitter and receiver.


At a mid-western electric company two combination tools were developed. One the screw driver and tweezers. The other is a wrench and screw driver.

The multiple-spinder air-operator nut runner for automobile wheels is another good example of combination tool.

20. Tools and materials should be prepositioned whenever possible.


Pre-positioning refers to placing an object in a predetermined place in such a way that when next needed it may be grasped in the position in which it will be used.

Tools are kept in specified holders in the form of socket, compartment, bracket or hanger all the time when there are not in use. They are returned or kept in the same position by the operator after they are used. The design of the holder is to be such that the tool is quickly released into its place. Also, it should facilitate quick grasping for use.

It is important to state again that, the holder of the tool should be designed in such a way that, the tool can  be grasped in the same manner in which will be held while being used.

21. Where each finger performs some specific movement, such as in typewriting, the load should be distributed in accordance with the inherent capacities of the fingers.


22. Levers, hand wheels and other controls should be located in such positions that the operator can manipulate them with the least change in body position and with the greatest speed and ease.

Unless a machine is fully automatic, the amount of work that it will produce depends to some extent upon the performance of the operator. The time taken by the operator to handle levers, hand wheels and other controls has an impact on production quantity.  

The operator should not be required to leave his normal working position to operate his machine. The controls of machines should be placed in such a way that he need not bend over or twist his body in an uncomfortable manner when manipulating  them.

Exhaustive studies were done to indicate good location for levers and hand wheels.



Example: Barnes have given the example of Jones and Lamson CNC Lathe. It was provided with a small control center, located at the front of the machine with an alpha numeric keyboard for instant on-line commands and editing, plus a CRT display. The operator has a greater access to all working areas.

Motion Reductions in a Paper Mill


 Workstation Improvements in a paper mill

    *       A machine feeder reduced arm motions from 5000 per day to zero, and output increased from 5000 pieces per day to about 15,000 (300% increase).
    *       Improvements in a paper counting task reduced finger motions from 45,000 per day to near zero, and productivity doubled.
    *       A unique device to tie ribbons eliminated much fastidious hand motions and sustained pinch grips, plus increased output over 30%.
    *       Unconventional tables for a precise, hand-intensive task enabled employees to alternate between sitting and standing, plus eliminated reaches and motions. Modifications in hand tools reduced grasping force.
    *       Mechanical changes and automation in a packing operation reduced hand motions from approximately 32,000 per day to 3200.
