Doctoral Research, Georgia Tech, 1/2002-6/2006.
Developed and tested performance analysis and design techniques of vehicle-based automated material handling systems. These techniques are based on analytic models rather than simulation. The approach promises reasonably accurate estimates with computation times that are acceptable in a design environment. Prof. Leon McGinnis, Georgia Tech.
Research Assistant, Georgia Tech, 1/2002-6/2006.
Collected, and statistically evaluated results of large scale simulation model of a generic 300mm wafer fab using AutoSched AP and AutoMod simulation software. Studies were mainly targeted towards evaluating faster modeling techniques, and evaluating the performance of clever dispatching and routing policies. Prof. Leon McGinnis, Prof. Spyros Reveliotis, and Dr. Doug Bodner, Georgia Tech.
Master’s Research, UCF and Lucent Technologies, 6/1999-2/2001.
Conducted a cost-benefit study of expanding the capacity of an actual wafer fabrication facility. Through group screening, a experimental design was used to identify the important factors in the facility that influence the performance measures, constructed the operating characteristics curves and evaluated the cost versus benefit of a set of improvement scenarios. Prof. Mansooreh Mollaghasemi, UCF.
Research Assistant, Intelligent Simulation and Training Systems Labs, UCF, 5/1999-7/1999.
Developed websites for graduate and undergraduate level classes in the Industrial Engineering and Management Systems department.
