講座摘要：

For modeling multi-server queueing systems, a standard assumption is that all servers are independent. However, demand for studying queueing systems with correlated servers was created about 60 years ago, motivated by various applications. In recent years, the importance of such studies has been significantly increased, supported by new applications of greater significance to much larger scaled industry, and the whole society. Such studies have been considered very challenging. In this talk, we present a new Markov modelling approach for queueing systems with correlated service times. We apply this new approach to a queueing system with arrivals according to a Poisson process and two positive correlated exponential servers, referred to as the $M/M_D/2$ queue.

This talk is based on joint research with Suman Thapa
