摘要:

In this presentation, we study process flexibility in a multi-period make-to-order production (MTO) system. Traditionally, process flexibility has been studied in single-period systems, because computing the optimal policy in multi-period systems is extremely difficult due to curse of dimensionality. Interestingly, researchers in applied probability have observed that under some flexible structural conditions, the Max-Weight type policies are near optimal.Motivated by this, we propose and formalize a notion of “effective chaining" termed the Generalized Chaining, which includes the chaining structure put forth by Jordan and Graves (1995) as a special case. Using this notion, we show that when the system has high utilization rate, very sparse structures can achieve almost the same backlog cost as the fully flexible system. More specifically, we provide an algorithm that produces a flexibility structure that is as effective as full flexibility with only K arcs, where K equals to the number of plants plus the number of products. The goal of this study is to make progress towards the better understanding of the key design principles of process flexibility structures in a multi-period environment, the study of which has been limited due to its inherent complexity.

This is joint work with Cong Shi from University of Michigan and Yuan Zhong from University of Chicago.

 

报告人简介:

Dr. Yehua Wei is currently an Assistant Professor in the Operations Management Department at Boston College. He has received his PhD in Operations Research from MIT in 2013, and prior to Boston College, he was an Assistant Professor in the Decision Sciences area at Duke University. His research interest includes designing sparse resource pooling systems, supply chain risk mitigation, and strategic customers in queueing networks. His research has won a number of awards, including 2nd place of the 2011 George Nicholson Paper Competition, 2nd place of the 2013 CSAMSE Best Paper Competition, and the 2014 Daniel H. Wagner Prize for Excellence in Operations Research Practice. Very recently, his paper co-authored with Alessandro Arlotto and Andrew Frazelle, was selected as a finalist of the 2016 MSOM student paper competition.
