Problem definition: We study customer-centric privacy management in service systems and explore the consequences of extended control over personal information by customers in such systems.Methodology: We adopt a stylized queueing model to capture a service environment that features a service...

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...

One of the primary concerns of urban police departments is the effective use of patrol cars. In large cities, police assigned to patrol cars typically account for more than 50% of total police manpower and their allocation has become particularly crucial in light of recent fiscal cutbacks. The...

Previous authors have shown that dynamic ratio scheduling rules do not always behave as intended. A recent proposal by Adam and Surkis (Adam, N. R., J. Surkis. 1980. Priority update intervals and anomalies in dynamic ratio type job shop scheduling rules. Management Sci. 26 (12, December)...

Dynamic priority dispatching rules in job shops require the computation of all job priorities in a work center queue every time a machine in the work center becomes idle. This is extremely costly. Alternative priority update procedures are studied and comparative results in terms of performance...
