Intelligent Simulation-Based Lot Scheduling Of Photolithography Toolsets In A Wafer Fabrication Facility, Amr Arisha, Paul Young
Intelligent Simulation-Based Lot Scheduling Of Photolithography Toolsets In A Wafer Fabrication Facility, Amr Arisha, Paul Young
Conference papers
Scheduling of a semiconductor manufacturing facility is one of the most complex tasks encountered. Confronted with a high technology product market, semiconductor manufacturing is increasingly more dynamic and competitive in the introduction of new products in shorter time intervals. Photolithography, being one of the processes repeated often, is a fabrication bottleneck. Lot scheduling within photolithography is a challenging activity where substantial improvements in factory performance can be made. The proposed scheduling methodology integrates two common approaches, simulation and artificial intelligence. Using detailed simulation modeling within a structured modeling method, a comprehensive model to characterize the photolithography process was developed. An …
A Template-Based Conceptual Modeling Infrastructure For Simulation Of Physical Security Systems, Ashu Guru, Paul Savory
A Template-Based Conceptual Modeling Infrastructure For Simulation Of Physical Security Systems, Ashu Guru, Paul Savory
Department of Industrial and Management Systems Engineering: Faculty Publications
Although simulation is one of the most innovative and cost-effective tools for modeling and analyzing a system, simulation studies often fail to provide any useful results. One reason is attributed to the fact that model formulation depends on the skills of the analyst. This paper describes a research to develop a conceptual modeling infrastructure to assist a simulation analyst in specifying components for studying physical security systems. The modeling framework has been programmed as an internet-based web application. Using the application, the successful development and implementation of a physical security simulation model will be aided by a defined scientific methodology …
Decision Factors For Cooperative Multiple Warhead Uav Target Classification And Attack With Control Applications, Douglas D. Decker
Decision Factors For Cooperative Multiple Warhead Uav Target Classification And Attack With Control Applications, Douglas D. Decker
Theses and Dissertations
Autonomous wide area search, classification and attack using Unmanned Combat Air Vehicles (UCAVs) is considered. The wide area search and attack scenario is modeled, capturing important problem parameters related to environment, seeker, and munitions. Probabilistic analysis is used to formulate and analytically solve for various probabilities, including the probability of mission success. Two methods are utilized. The first examines the sub-events required for various events to occur. The second utilizes a Markov chain approach. General expressions are first obtained that are applicable to any assumed a priori distributions of targets and false targets. These expressions are subsequently applied to a …
A Case Study Of Teaching A Quantitative Course Using Archived Streaming Video, Paul Savory
A Case Study Of Teaching A Quantitative Course Using Archived Streaming Video, Paul Savory
Department of Industrial and Management Systems Engineering: Faculty Publications
This case study highlights some of the issues and difficulties experienced in teaching a quantitative course using three methods of delivery: in-class to an audience of students, television broadcast over a satellite system to distance students, and archived streaming video accessible by students. The discussion is applicable to administrators and faculty exploring the option of teaching a course using multiple delivery approaches.

Investigating The Optimal Management Strategy For A Healthcare Facility Maintenance Program, Daria J. Gaillard
Investigating The Optimal Management Strategy For A Healthcare Facility Maintenance Program, Daria J. Gaillard
Theses and Dissertations
Reacting to the need to transform and the increasing pressure to outsource all non-core activities, Air Force Material Command Surgeon General discontinued its previous use of full service contracts with original equipment manufacturers and adopted a relatively new maintenance outsourcing strategy: strategic partnering with an equipment management firm. The objective of this study is to create a decision-model for selecting the optimal management strategy for a healthcare organization's facility maintenance program. This study used personal interviews with facility management personnel from MAJCOMs to collect and analyze data. This study offers a re-conceptualized framework for viewing and understanding the various maintenance …
Keys To Successful Implementation And Sustainment Of Managed Maintenance For Healthcare Facilities, Elizabeth A. Waggoner
Keys To Successful Implementation And Sustainment Of Managed Maintenance For Healthcare Facilities, Elizabeth A. Waggoner
Theses and Dissertations
Health care providers are faced with two critical issues in today's evolving marketplace: lowering operational costs and achieving more efficient, cost-effective methods to deliver high quality patient care. The rising costs of healthcare and decreasing budgets have placed additional strain on the United States Air Force Medical Service to aggressively lower its facilities' costs. With fewer funds and less personnel, the Air Force medical service is re-evaluating its current maintenance outsourcing implementation practices and reexamining how these strategies might be implemented and sustained more successfully. This research offers some of the foundational needs for designing, implementing and sustaining any type …
Phase-Type Approximations For Wear Processes In A Semi-Markov Environment, Christopher J. Solo
Phase-Type Approximations For Wear Processes In A Semi-Markov Environment, Christopher J. Solo
Theses and Dissertations
The reliability of a single-unit system experiencing degradation (wear) due to the influence of a general, observable environment process is considered. In particular, the failure time distribution is evaluated using only observations of the unit's current operating environment which is characterized as a finite semi-Markov process (SMP). In order to impose the Markov property, generally distributed environment state sojourn times are approximated as phase-type (PH) random variables using observations of state holding times and transition rates. The use of PH distributions facilitates the use of existing analytical results for reliability evaluation of units subject to an environment process that evolves …
Thin-Film Simulation Model For Comparing Production Schedules In A Semiconductor Fabrication Facility, Amr Arisha, Paul Young
Thin-Film Simulation Model For Comparing Production Schedules In A Semiconductor Fabrication Facility, Amr Arisha, Paul Young
Conference papers
Analysis of advanced manufacturing systems in any manufacturing industry requires certain level of knowledge about the system. Flexible manufacturing cells, in particular, are commonly used in most wafer fabrication to provide the ability to change product without requiring the construction of new manufacturing plant. This level of flexibility comes at a significant capital cost and, in order to achieve the maximum potential of each cell, it is essential to characterize and establish the performance of these cells in detail before a new production plan is implemented. Using state-of-the-art computer simulation and a structured modelling methodology a generic model of flexible …
