Abstract: Modelling delays due to multiple resource synchronizations are important to accurately estimate the customer waiting times (at an external queue) in manufacturing, logistics, communication, and health-care systems. Such waiting time measures are typically used for sizing resources and buffer capacities, and thereby minimizing customer waiting time probabilities. In this regard, semi-open queuing networks (SOQNs), which decouple the arriving customers/transactions from the network resources using a synchronization station (also known as a semaphore queue), can potentially capture the customer/transaction waiting times/costs more precisely and provide a rich network modelling construct. In this workshop, the concept of SOQNs will be introduced and several stochastic models for manufacturing, logistics, and service systems will be discussed. Finally, the potential research areas in SOQNs will be presented.
About the facilitator: Debjit Roy is an Institute Chair Professor in the Operations and Decision Sciences area at the Indian Institute of Management Ahmedabad, India. He holds a Ph.D. in Industrial Engineering (with a major in Decision Sciences/Operations Research and a minor in Computer Science) and an MS in Manufacturing Systems Engineering from the University of Wisconsin-Madison besides an M.Sc. (Engineering) from the Indian Institute of Science, Bangalore, India. His research focuses on analyzing performance of service and logistics systems such as container terminals, automated distribution centers, vehicle rental, healthcare, and restaurant systems, using quantitative methods such as stochastic modeling and optimization.
