Summary of Expertise:

Listed with other top experts in: 

While he trained as a mechanical/industrial engineer and has extensive experience in teaching all aspects of industrial engineering, Expert has specialized in the application of discrete event simulation techniques. He considers simulation the most viable operation research technique for modeling and experimenting with complex manufacturing or service systems. Expert is skilled in the development of interactive simulators built on the Arena simulation language, which are used by clients to simulate a specific set of manufacturing systems. Expert is experienced at viewing simulation from both the "big picture" perspective within an organization and at the "micro" level required to de-bug and validate simulation code. In addition, he is knowledgeable in the areas of operations research, mathematical modeling, and statistical data analysis.

discrete-event simulation





Since 1967, Expert has developed computer-based simulation models for a wide variety of systems. These include airline baggage transfer, automotive assembly, commercial laundry, electrical fabrication, high-speed packaging, jet engine overhaul, JIT receiving, Army personnel, Air Force inventories, and underground coal mines. These models have used a variety of the simulation languages. While his work over the past 16 years has been personal computer and workstation based, Expert had previously worked on most major mainframe computer systems.

computer simulation

Expert has developed simulation models for a wide variety of manufacturing systems. These models have capitalized on the similarities in manufacturing operations across a wide variety of industries. For example, equipment failure properties are generally independent of the equipment's particular application. Expert has been involved with engineering projects in a wide variety of manufacturing areas with direct manufacturing experience in automotive assembly. He is also trained in the techniques of manufacturing production planning and control.

manufacturing systems modeling

Expert has used and taught a wide variety of simulation languages over the past 25 years. He has also advised organizations on the selection of the most appropriate simulation language for their current and future applications. He has tracked the life cycles of simulation languages by observing their presence at technical conferences in the U.S., Japan, and Europe, their advertisements, and their references in the published literature. He has seen many simulation languages make an initial introduction but rapidly fail due to a number of shortcomings. Expert has become very skeptical of any new simulation language. He is well aware of the technical support and marketing effort required to successfully bringing a simulation language to the commercial market. He is knowledgeable of several simulation languages including Arena/SIMAN, GPSS, SLAM, WITNESS, PROMODEL, and SIMSCRIPT.

simulation programming language

Expert has used SIMAN since 1982. Most of this use has involved developing special purpose simulators for service and manufacturing application. In addition, he has served as a Beta tester for SIMAN IV (1989) through Arena 4.0 (1999). Over the years, he has identified many technical errors in the Arena/SIMAN language and has followed through on their resolution. He has also made many suggestion for improvements in the Arena/ SIMAN language. He has taught the application of the Arena in graduate level manufacturing engineering courses. He won first prize in the SIMAN user conference model building contest. He has used both the discrete event and the continuous simulation techniques supported by Arena.


Expert has extensively used Visual Basic for Applications (VBA) to link Arena with Office tools, such as, Excel, Access, and Visio. Much of his work has involved writing interactive programs to support simulation software and data analysis. The method he has developed for this form of simulation automation has been named "Industrial Strength Simulation Modeling."

Visual Basic programming

Expert has extensively used FORTRAN on a variety of computer systems for over 35 years. Much of his work has involved writing interactive programs to support simulation software and data analysis. Currently, he is using both Microsoft and Watcom FORTRAN on IBM personal computers. He is also using C routines in conjunction with FORTRAN to support functions not available in FORTRAN. In addition, Expert has developed many graphical displays using FORTRAN.
