A fuzzy approach to the flow control problem

We consider queueing systems in which arriving customers may be accepted or rejected. The objective is to determine the optimal admission policies so as to maximize the average profit (reward minus cost) over an infinite hori zon. In this paper we use fuzzy logic to solve two problems for which analy tical solutions exist. Fuzzy logic produces identical policies to the analy tical ones and, therefore, these problems serve as benchmarks for further w ork. We then tackle a new problem with two arrival streams and parallel ser vers. The fuzzy approach is tested with simulation, and appears to be effic ient and promising in areas -where analysis is limited.
