Discrete Event Simulation Using Excel/VBA David Elizandro and Jessica Matson Tennessee Technological UniversityAbstractThe spectrum of discrete event simulation modeling courses in industrial engineering programsvaries from an emphasis on learning concepts of discrete event simulation to modeling simplesystems using a commercially viable simulation language. Often, when the emphasis is onlearning a commercial language, much of the course becomes training at the expense ofconcepts. As a result the student has a basic understanding of the language and modeling butlimited understanding of discrete event simulation concepts. In either case, modeling

IntroductionMicroprogramming is a concept dating back to the early 1950's1 and is widely used in the designof modern computers. The concept is easy to understand and presents a general solution to thecontrol problem for a central processing unit. Students who understand how microprogrammingworks from a logical point of view have insight into the inner workings and magic of digitalcomputer systems that is difficult to obtain otherwise.

Virtual laboratoriesprovide students access to simulated experiments or animated dynamic system simulations.Remotely accessible laboratories allow students to access via the Internet real-time experimentswith video feedback. Inter-university laboratories engage students in a collaborative effort toconsolidate resources for a single project. The goal is to effectively engage students in the engineering process of modeling andcontrolling dynamic systems. By implementing and assessing these laboratory formats, weintend to help students achieve the following objectives: 1. Enhance conceptualization and use of fundamentals through multiple means of visualization. The laboratory formats proposed will incorporate

In this case, the students were also in a computer science course,but the model readily transfers to engineering education and will be used in an engineeringeducation research grant on complex problem solving skill from NSF’s Human and SocialDynamics Program.

lab times.• Limited resources to support students outside labs and the classroom: In many cases, no lab assistant support is available.• Limited equipment to support lab assignments: Because lab equipment is often expensive, students must often work in groups. For example, an industrial scale PLC—such as an Allen Bradley RSLogix 5550 processor and a set of I/O cards—costs about $8000.To help offset these obstacles, in recent years, a variety of computer and networkingtechnologies have been developed. For example, remote laboratories (also known as e-Lab,Tele-Lab)5,6, virtual laboratories8,9,10,11, and hybrid laboratories6 have been developed to reducelab equipment setup costs and increase accessibility.

This decision is consistent with the work of Harmon and Chung, who havedemonstrated that simulations can be used to create authentic design experiences.12,13 Moreover,computer animations can enhance student engagement, promote visual learning, and enhance theunderstanding of complex concepts.14The Contest FormatBased on these considerations, we decided to use information technology to facilitate broadparticipation in the contest, to reduce its cost, and to enhance the realism of the designexperience.
