An Undergraduate Systems Engineering Design Project for Using Constructive and Virtual Simulation for an Armed UAV Design
Suzanne Oldenburg DeLong and Paul West (United States Military Academy)

This paper presents a design project for undergraduate systems engineering students in which Armed Unmanned Aerial Vehicles (AUAV’s) are designed, using the systems engineering design process taught at the United States Military Academy, and tested using constructive and virtual simulation. These results are compared to theoretical results obtained through applying Lanchester analysis. Students first analyze the stakeholders’ needs and develop alternatives. The students research commercial off the shelf (COTS) UAV airframes, sensors and weapon systems that meet the stakeholders’ needs. Using design of experiments and response surface optimization, laboratory experimentation is conducted using Janus simulation and Janus Evaluator Tool Set (JETS) output software to test the feasible alternatives under varying weather conditions and altitudes to examine performance against a predetermined enemy threat. The students evaluate the alternatives using multi-attribute utility theory and encompassing all the objectives defined in the stakeholder analysis. Sensitivity analysis is applied and a recommendation is made to the decision maker.

Linda Arouses a Sleeping Barber
John H. Reynolds (Mary Washington College)

This paper presents an approach that gives students insights into parallelism and exposure to discrete-event simulation techniques without requiring that they have formal courses in either. I apply the rather curious Linda coordination model to the classic Sleeping Barber Problem used frequently to illustrate inter-process communication activities in operating system courses. Normally, customers seeking haircuts are represented as processes spawned as faceless entities with no regard to inter-arrival times or proper ordering of departures for those who get cuts. This paper uses elementary discrete-event simulation techniques to introduce this sought for realism while preserving the original motivation of using the Sleeping Barber to demonstrate process concurrency.

Using Simulation to Teach Business Processes Design and Improvement
Marvin S. Seppanen (Productive Systems) and Sameer Kumar (University of Saint Thomas)

A course titled, “Process Design and Improvement: Computer Based Tools" was developed and offered by the authors in Fall 2000 and 2001 for part-time graduate students in Manufacturing Systems Engineering and Technology Management programs at the University of St. Thomas, Minnesota. The objective of the course is to introduce students to the current software and methods used to organize data and model manufacturing and industrial systems through virtual representation of business operations choosing problems from their workplaces. The course was created to make the complex processes and tools of computer modeling more accessible to non-specialists for a better understanding of how their operations work. It is not unusual that people only know a small part of their overall system. This gives them a way to see the big picture. A case study illustrates the application of these tools.

Panel Discussion on Using Simulation to Teach Probability: Words

Panel: Using Simulation to Teach Probability – Words and Deeds
Matthew Roshenshine and Russell R. Barton (The Pennsylvania State University), David Goldsman (Georgia Institute of Technology), Lawrence M. Leemis (The College of William & Mary) and Barry L. Nelson (Northwestern University)

This panel has been put together to promote the use of simulation as a teaching tool to expedite the learning and, more importantly, the understanding of probability theory. "In a nutshell," the thesis upon which this panel is based is that the simulation approach is more effective than a mathematical approach on a stand-alone basis. It also dominates any statistical approach as a pedagogical tool.
