Dynamic priority rules for cyclic queues with limited service regime
A cyclic service system with two stations operating under limited service regime has been analyzed, assuming poisson arrivals and exponential service at each service station. Zero switch-over times have been assumed. A thorough simulation study has been conducted, and guidelines have been obtained in the control of the behavior of such systems. It has been shown that the choice of service limits in symmetrical service systems has no effect on the average total waiting time in system, and that the performance measures for such systems can easily be obtained by converting the system into an M/M/1 system. This approach has been proven to be invalid for non-symmetric service systems. In the case of non-symmetric systems, setting the service limit at the station with longer average service duration at 1, and fixing it as high as possible for the station with the shorter average service duration has been shown to be the optimal strategy for minimizing the average delay in the system.
