Epstein Institute Seminar Series / ISE 651 Seminar

Speaker: Dr. Gideon Weiss, Professor, Statistics, University of Haifa, Israel

Talk Title: "Skill Based Service Systems"

Series: Epstein Institute Seminar Series

Abstract: We consider systems with several types of customers and several types of servers, where compatibility of servers to customers is given by a bipartite graph. This is motivated by call centers with skill based routing, and by assigning kidney transplants to patients. A common approach is provided by infinite first come first served matching of two infinite multi-type random sequences. We obtain explicit results for this model, and show how to extend them to a host of queueing models, including loss systems, stable queues, overloaded queues, and overloaded queues with abandonments.
