Ph.D. candidate to give talk on simulating, optimizing procedures in nuclear medicine

Eduardo Pérez, a Ph.D. candidate in the Department of Industrial and Systems Engineering, will give a talk Monday (March 22) at 3 p.m. in Room 203 of the Zachry Engineering Center on campus.Pérez's talk, Simulation and Optimization for Scheduling Multi-Step Sequential Procedures in Nuclear Medicine," is part of the department's seminar series, sponsored by Parsons Corp.Abstract Increased demand for specialized health care services has been identified as one of the causes of increased health care costs in the U.S. Nuclear medicine, a sub-specialty of radiology, uses relatively new technology to diagnose and treat patients. Procedures (tests) in nuclear medicine require the use of radiopharmaceuticals with a limited half-life and involve several steps that are constrained by strict time windows and require multiple resources for completion. Consequently, managing patient service in nuclear medicine is a challenging problem with limited research attention. In this seminar, we present a discrete event system specification (DEVS) simulation model and scheduling algorithms for nuclear medicine patient service management that consider both patient and management perspectives. DEVS is a formal modeling and simulation framework based on dynamical systems theory and provides well defined concepts for coupling components, hierarchical and modular model construction, and an object-oriented substrate supporting repository reuse. We report results based on a real nuclear medicine clinic and historical data using both patient and management performance measures. The results provide useful insights regarding the management of patient service in nuclear medicine. While this work focuses on nuclear medicine, results will find generality in other health care settings.Biography Eduardo Pérez is a Ph.D. candidate in the Department of Industrial and Systems Engineering at Texas A&M University. He received his Bachelor of Science degree in industrial engineering in 2004 from University of Puerto Rico, Mayagüez Campus. His research interests include systems modeling, discrete event simulation, and stochastic optimization and application of these methods in patient service and resource management in health care and operations and maintenance in wind energy. He successfully defended his Ph.D. dissertation March 11 and will receive his degree in May. His co-advisors are Dr. César Malavé and Dr. Lewis Ntaimo.
