Fuzzy control of arrivals to tandem queues with two stations

We consider two queues in tandem, each of which has its own input of arrivi ng customers, which, in turn, may either be accepted or rejected, Suppose t hat the system receives a fixed reward for each accepted customer and pays a holding cost per customer per unit time in the system. The objective is t o dynamically determine the optimal admission policies based on the state o f the system so as to maximize the average profit (reward minus cost) over an infinite horizon. This model finds applications in flow control in commu nication systems, industrial job shops, and traffic-flow systems. In this p aper, a novel approach is presented using fuzzy control. This approach expl icitly finds the optimal policy, which up until now has defied analytical s olutions.
