Integration Of Artificial Neural Networks And Simulation Modeling In A Decision Support System, Kenney Lecroy

Retrospective Theses and Dissertations

A simulation based decision support system is developed for AT&T Microelectronics in Orlando. This system uses simulation modeling to capture the complex nature of semiconductor test operations. Simulation, however, is not a tool for optimization by itself. Numerous executions of the simulation model must generally be performed to narrow in on a set of proper decision parameters. As a means of alleviating this shortcoming, artificial neural networks are used in conjunction with simulation modeling to aid management in the decision making process. The integration of simulation and neural networks in a comprehensive decision support system, in effect, learns the reverse …

Manufacturing Curriculum Issues Of Two-Year Mechanical Engineering Technology Program In Taiwan, R.O.C., Chuan-Chun Wu

Dissertations and Theses @ UNI

The purpose of this study was to evaluate current practices and possible changes in the mechanical engineering technology manufacturing curriculum in Taiwan's two-year junior technical colleges. The study was based on survey responses from three populations: (a) graduates of mechanical engineering (manufacturing division) programs in two-year junior technical colleges, (b) their manufacturing supervisors, and (c) their company chief executive officers (CEOs). The survey was designed to develop responses for following:

1. Determine the degree of importance of courses in the current Taiwanese two-year curriculum in manufacturing, in the opinion of the three groups surveyed.

2. Determine what the future curriculum …

Extending Simulation’S Advantages To Novice Model Builders: Intellisim Tutorial, Paul Savory, Gerald Mackulak, Jeff Cochran

Department of Industrial and Management Systems Engineering: Faculty Publications

The potential benefits that discrete-event simulation offers are impeded by the high level of expertise necessary to successfully conduct a sound simulation study. As a solution, this paper introduces IntelliSIM, an intelligent simulation environment. Using this environment makes simulation more accessible to users by reducing the need for extensive experience or training. One of IntelliSIM’s key features for accomplishing this is a tutorial and training module that quickly acquaints a novice simulation user with IntelliSIM’s features and the process of performing a simulation study. This paper discusses this tutorial by explaining how IntelliSIM develops a simulation model, thus illustrating how …

Ascertaining Important Features For Industrial Simulation Environments, Gerald Mackulak, Jeffery Cichran, Paul Savory

Department of Industrial and Management Systems Engineering: Faculty Publications

Recent years have witnessed the development and commercial release of multiple simulation tools, environments, and intelligent simulators. Each release seems to contain additional advanced features designed to simplify simulation use and increase the productivity of model builders. But to date, no one has addressed feature definition from the viewpoint of a simulation practitioner. This paper discusses our efforts to identify and prioritize simulation features deemed most desirable from the practitioner viewpoint. A series of three questionnaires were developed and administered to a group of qualified simulation practitioners. With results that are of interest to simulation users, researchers, and simulation software …

Teamwork In The Workplace: A Discovery Of The Work Processes One Team Used To Meet Its Goals, Thomas Andrew Hassler

Engineering Management & Systems Engineering Theses & Dissertations

A century-old disagreement in academia surrounds the question of whether individuals acting alone accomplish all work or whether workers can truly act in concert to meet management's production requirements. Total Quality Management (TQM) is a powerful force today in the industrial world, and the formation of teams to solve short-term problems is one of its fundamental techniques. This dissertation focuses on a particular TQM team with the purpose of understanding the processes it used to meet its goals. This ten-member team functioned for about one year and was assigned goals leading to improved accelerator reliability. The investigator was a member …

The Science Of Simulation Modeling, Paul Savory, Gerald Mackulak

Department of Industrial and Management Systems Engineering: Faculty Publications

Many people refer to simulation model building as an “intuitive art”. This implies that modeling can only be done by a select group of highly trained creative people and thus isolates many from considering simulation as a usable tool. Model building is a science that is learned through education, training and experience. In this paper, we discuss the role of science in performing a simulation study. We illustrate the teaching of the science of simulation by discussing the simulation curriculum at Arizona State University.
