The Maximal Covering Location Problem (MCLP) has been the focus of considerable attention both in research and practice for some time, and numerous extensions have been proposed to broaden its appeal and enhance its applicability. In this paper, we are concerned with the addition of workload...

By the very nature of the demand that they serve, emergency service systems require that timely service be readily available to those who need it. Yet, the distinct possibility exists that the closest facility will be occupied with another call for service, and when this primary responding unit...

Given the widespread use of the hub and spoke network architecture and its growing importance to competitiveness in logistics, communication, and mass transportation, there has been considerable interest by practitioners and researchers alike in finding efficient methods for designing such...

Quite often in the creation of analytic models for decision problems involving multiple objectives, some of the objectives are excluded. This can be due to their being consciously or unconsciously hidden by the decisionmaker or due to the lack of quantifiable performance measures. The normal...

The problem of determining optimal reorganization policies for databases which employ file structures with overflow chaining is studied. The dynamics of the file performance driven by update transactions and reorganizations is formulated as a stochastic control model which incorporates...

The multi-resource generalized assignment problem is encountered when a set of tasks have to be assigned to a set of agents in a way that permits assignment of multiple tasks to an agent subject to the availability of a set of multiple resources consumed by that agent. This problem differs from...
