Abstract
Several available models for urban emergency services, and in particular the hypercube queueing model, assume that the service time is independent of the locations of the call for service and possibly the dispatched unit. The effects of this assumption on the accuracy of the estimates for the system's performance criteria are investigated for a simple two-servers, two customers system. A modified, more accurate approximation method is suggested for such a simple system.Keywords
