Title: Optimal Maintenance Intervention in Partially Observable Multi-Component Systems

Date/Time: April 17, 2024, 13:40-14:30

Location: FENS G035

Abstract:In today's world, many remotely operated systems are becoming ever more complex and the number of components in these systems keeps on growing. Examples include water pump systems for irrigation or mining purposes, off-shore power generation systems --the focus application area in this talk. Such systems are typically mission-critical for their users. Hence, it is of utmost importance to keep them in operating condition via well-designed maintenance policies. It makes sense for such policies to make use of whatever information is available no matter how limited.  This approach is commonly labeled as condition-based maintenance (CBM) planning. In this talk, we will present a novel methodology to manage maintenance interventions as well as spare part quantity decisions for such systems.  Our methodology is based on reducing the state space of the multi-component system and optimizing the resulting reduced-state Markov decision process via a linear programming approach. This methodology is highly scalable  and capable of solving large problems that cannot be approached with the previously existing solution procedures due to the curse of dimensionality.

Bio: Dr. Murat Fadıloğlu is currently professor of industrial engineering at Yaşar University. He received his B.S. degree in electrical engineering from Bilkent University in 1993. He then completed his doctoral studies at the Department of Industrial and Systems Engineering of University of Florida in 1998. He previously worked at Bilkent University, Izmir University of Economics, and American University of the Middle East. His research interests include Reliability and Maintenance, Energy Systems,  inventory/production systems, queueing models, stochastic modeling, dynamic programming, state estimation, and data analytics. He is interested in developing new innovative courses on the interface of computer science and industrial engineering. He is an ardent advocate of an interdisciplinary future for academia.  Dr. Fadıloğlu is a member of the Institute for Operations Research and the Management Sciences and of Operations Research Society of Turkey.  He enjoys sports such as bicycling, swimming, and squash, literature, philosophy and world music, cinema and cuisines.
