A Comparison of the Multiple Dispatch andM/M/cPriority Queueing Models of Police Patrol
Management Science · 1984 · Volume 30 · Issue 6
Abstract
In many cities, a substantial fraction of calls for police service require more than one patrol car. We compare Green's multiple dispatch queueing model to several M / M / c -based approximations for multiple car dispatching that are obtained by adjusting the parameters. We found that none of the approximate models yields consistently reliable results under a broad range of conditions. The best approximations are produced by reducing the actual number of servers. Increasing the call rate gives the worst results.
