- INTRODUCTION
- INDUSTRIAL ENGINEERS TOOLBOX
-
- In business today `down sizing' seems to be the in word.
- It is a term used to mean that a business is taking advantage
- of Parkinson's law, which says in effect that the available
- workload will tend to completely fill the available time.
- Or stated another way, workers will pace themselves to use
- the allotted time. What isn't stated, when the term is
- used, is that the time frame was too large to begin with.
- Either because, the workload wasn't properly understood (how
- long will this process take?) or there was an unexpected down
- turn in the demand creating the workload. In either case,
- there is no sure way for today's manager to know how much to
- down size without knowing the true value of the workload.
- Just about everyone at one time or another has had or will
- have someone at their right hand giving them specialized
- advice. We see it on TV in congressional hearings and in
- court proceedings. The technical advice is supplied to the
- participants, on both sides, by their right-hand-man. That
- is precisely the Industrial Engineer's role in the business
- world. He is a consultant on engineered values to apply to
- every day business problems. That is not to say that he has
- all the answers needed, but within his area of knowledge and
- experience, he can be depended on to give valid information
- to be used by managers to make the best decisions they can.
- He is basically a management consultant.
- The Industrial Engineers Toolbox was a natural progression
- out of the Facilities Management Series, and incorporates
- those programs into the toolbox. It was developed because
- no collection of the programs within it could be located,
- and it was felt that a set of these tools organized into one
- toolbox would be beneficial to an analyst performing
- management studies. An users manual has been written only
- for the Facilities Management Series. The balance of the
- programs are either well enough menu driven or
- are of technical enough nature to require a certified
- analyst, and as such, a user's manual was deemed not
- required. The highly technical programs, such as MTM, are
- written so as to protect the uncertified person from faulty
- judgement. In those programs a statement is always made to
- the effect that no attempt is made to teach the discipline.
- The non industrial engineer is not excluded from using these
- programs, but should be encouraged to learn the more
- technical areas as they are needed. In this manner the
- series has enough depth to become ever more valuable to the
- user as they become more expert, but can be of value also
- from the first day. It can be like a Hoehner Marine Band
- harmonica, but is like a Chromonica, allowing sharps, flats,
- and varying shadings to problem solving. If from evaluation
- of questions coming from registered users a need is indicated
- for additional user manual, it will certainly be written.
- An industrial engineer's efforts can be directed in
- numerous directions. Five of these areas are Facilities
- Management, Facilities Acquisition, Decision Analysis, Value
- Engineering, and Work Measurement. At this point the
- toolbox has programs directed towards these areas. Since
- the area is dynamic, development work is continuing to
- expand the toolbox, and each release should have some new
- tools. In places the areas tend to merge and overlap, so
- that a program can be used in more than one area. Each
- program is a module or tool within the control of the main
- menu program which allows each program to blend into an array
- that gives the appearance of a very large program. Yet each
- program can be stored in floppy disk, streamer tape, or
- bernoulli media, waiting, away from the computer for the time
- it is needed. The Main menu allows the analyst to keep only
- the tools most commonly used, ready at hand, while the
- balance are left available but not using storage space. The
- Main menu alerts the analyst when a tool called for must be
- loaded. Only a modular program approach accommodates this.
- What follows is where each tool fits into the overall
- scheme of things and how it is valuable to that scheme. No
- valid advice can be given without understanding the question,
- and anything that can have a value assigned to it can be
- managed. Each of the programs that follow allow the analyst
- to assign values to a given function or aid visualization of
- values that have been assigned by a previous program. These
- programs are analysis aids, only. 90% of true analysis
- occurs when the analyst is forced to put the facts and
- figures developed in the study into written form. A
- narrative or report, whatever it is called, presents the
- problem, the study data, the conclusion from the data, and
- recommendations of alternatives for solution of the problem.
- Most will also include a study showing the impact to the
- operations of each alternative. The toolbox does not
- provide a text editor. There are numerous good ones on the
- market.
- The Layout Planning program is used to aid in Facilities
- Management, Work Measurement, Manpower Planning and
- Facilities Acquisition. In facilities management, one
- essential consideration is efficient and optimum use of the
- facilities. Layout Planning accomplishes this through
- consideration of which operation or department should be
- neighbor to which other operation or department within the
- facility, multi-floors can be considered also. After that is
- accomplished, each operation or department is considered for
- detailed placement of furniture and equipment within the
- operation or department. Using the Furniture and Equipment
- program to develop Work Station Units (basic modules showing
- total space, specific standardized layout of furniture,
- equipment and operator space plus allowance for aisles),
- those work station units can be blocked into an operation or
- department with other work station units and modified to meet
- existing need and provide a standardized detailed layout.
- One key in work measurement is, how much time is required
- because of required walking, both within and without an
- operation or department. The distance information is
- developed in Layout Planning and in Furniture and Equipment
- Survey, and can then be developed into standard time using
- MTM. By developing the data in Layout planning, the analyst
- is developing staffing requirements to validate the furniture
- and equipment needs. These needs can either be present or
- sometime in the future. To develop future needs the Decision
- Analysis program has compounding algorithms available, and
- the Statistics program allows regression analysis and or
- random sampling and probabilities. When extending the
- analysis into the future you are looking at the operations
- requirements for possible replacement (acquisition). By
- putting layout planning at the very core of your planning you
- begin to look at facilities as functional entities before
- looking at their form (functional buildings can be attractive
- but not all attractive buildings are functional). Are you
- in business to look attractive or perform a function? As
- you are probably beginning to see the programs within the
- toolbox are interdependent and yet can stand alone, depending
- on how much depth you want to put into your study. Layout
- of facilities on a site can be accomplished also.
- The Furniture and Equipment Survey as mentioned above is
- needed if, one you are going to rearrange your layout, and
- two if you are anticipating moving into a different building.
- The furniture and equipment program develops work station
- unit data, equipment costs and square footage requirements.
- You can identify furniture and equipment by floor and
- operation or department. This information dovetails with
- the Overhead Cost program. It is also used in the Custodial
- Requirements program. Depending on the ambition and
- sophistication of the analyst, the data developed here can be
- used to evaluate furniture and equipment usage, identifying
- unused furniture and equipment, methods improvements,
- additional furniture and equipment needs. Once again the
- thrust is to optimization and efficiency.
- The Overhead Cost program allows development of the
- overhead cost of each operation or department. The costs
- aren't intended to be developed to a degree of accuracy that
- an accountant would appreciate, but rather as a measuring
- device to draw the attention of first line managers to an
- area of facility management often overlooked. It can turn
- the spot light on poor housekeeping, furniture and equipment
- management, utilities management, etc.. This program uses
- data from the Furniture and Equipment program and the
- Custodial Requirements program.
- The Custodial Requirements program uses data from the
- Furniture and Equipment program and allows development of
- custodial requirements for each function required of
- custodians. It develops requirements for the workroom by
- operation or department, and can be used to develop employee
- work assignments when used with a detailed layout drawing
- developed in PC KEYDRAW or some other CAD program (even
- AutoCad if you are ready to spend or have spent $3,000.00).
- A drawing can show blocked out assignments with codings to
- indicate cleaning needs and frequencies. Also the program
- develops work hour requirements including fringe to develop
- staffing requirements.
- The Graphical Representation program uses data developed
- in the Layout Planning, Furniture and Equipment Survey, and
- the Overhead Cost programs. This program develops scaled
- graphs for visualization of data developed above, from
- calibration charts to overall cost/operation charts. This
- program does not stand alone. It requires at least one of
- the four programs mentioned above to be able to graph
- anything.
- The last program in the Facilities Management Series is
- the Space Relationship program. This program takes combined
- flow and service rankings from the Layout Planning program
- and puts the affinity pairs of operations or departments in
- rank order in a table to be used in a CAD program to draw the
- Space Relationship Diagram (Block Diagram). The listing
- also gives suggested length of the side of the square for
- square footage of each operation. This allows a starting
- place at a square to be ran, by the analyst, into the shape
- of best fit. While the other programs aid in developing
- this data, only this program and the Furniture and Equipment
- Survey data are carried over into PC KEYDRAW or another CAD
- program. Where eventually a detailed furniture and
- equipment layout drawing can be developed. As mentioned
- earlier then data from the other programs can be overlaid on
- either the block or detailed drawings.
- PC KEYDRAW needed some customization to make it more
- compatible with the thrust of these programs, so two
- libraries were developed to accomplish this. The first is
- a library of architectural symbols, to aid in making facility
- drawings. The second is a library of flow chart symbols, to
- be used in developing the various process charts used in work
- measurement. This library is accessed from each individual
- process analysis program and brings up the appropriate form
- header along with a help page to show how to access the
- symbols needed for insertion on that form. Of the process
- analysis procedures only Simo Charts goes directly from the
- Main Menu into PC KEYDRAW. There is one other bonus library
- included, and that is a library of electrical engineering
- symbols, for possible work in schematics.
- The Work Measurement Series starts with the various process
- charts: Operations Process, Flow Process, Operator Process
- (Right and Left Hand), Man-Machine Process, and Simo (Memo-
- motion using Therblig symbols to chart). The Simo chart is
- rarely, if ever, used any more but was included for
- completeness. Each procedure gives a fast track to overall
- understanding of a complex procedure or operation. The
- process charts are useful in any study, from Facilities
- Management through Value Engineering, where understanding of
- a process or function is required.
- Winding up the Work Measurement series is the Element
- Analysis program. Since Methods Time Measurement (MTM) is
- of a technical nature that requires analysis by trained
- analysts, the Element Analysis program performs only the
- grunt work of filling out the various forms. Routine
- calculations are performed, but the analyst must use a Time
- Measurement Unit (TMU) chart supplied by the MTM Association.
- The forms do provide total seconds, minutes, and hours for
- each element and the total operation or method analyzed,
- after the analyst has filled in the motion descriptions,
- frequencies and TMU's. There is a summarization form also.
- Value Engineering, like MTM, is another area where
- untrained analysts could develop conclusions hazardous to
- good management decisions. However, if the menus are
- followed, a group of people could come to some functional
- activity simplifications. The menu steers selection of the
- VE team, also. The trained analyst can through the use of
- OVAL (Organization Value Analysis Logic) analyze the office
- environment for down sizing. This procedure helps to
- question activities or parts not supporting the intended
- function of the item or operation under study.
- Most every study should present alternative solutions for
- management consideration. To aid in alternative evaluation
- the Decision Analysis program is included. This program
- allows the analyst to look at the economic impact of each
- alternative through the use of discounted differential cash
- flows. It also develops salvage value for buildings and
- land, and develops depreciation schedules (in straight line
- or sum of the years methods). Amortization schedules can be
- generated, showing fixed payments for the entire term, single
- additional principle payments at specified dates, or fixed
- additional principle payments starting at a specified future
- date. This feature allows looking at various prepayment
- strategies to evaluate alternative strengths and weaknesses.
- Each of the six compound interest algorithms can be called to
- perform individual calculations.
- The final program in this version is Statistical Analysis.
- While there are numerous statistical programs on the market,
- it was felt that one should be included in the toolbox.
- This program uses the random number generator to develop a
- listing of random samples from a selected sample size. It
- allows the analyst to perform regression and correlation
- analysis. It uses universe standard deviation to avoid bias,
- and looks at normal distribution, `t' and chi square. The
- program allows repeated passes with the data until the
- analyst wants to quit. For those who can't let go of
- reference tables, normal distribution,`t', and chi square
- tables are provided as help screens and can be referenced for
- insertion data.
- With this array of programs accessible in modular form,
- the analyst needs only a manpower planning module to allow
- performing a fairly thorough operations review. A Manpower
- Planning module is in development now for release in the next
- version.
