Abstract:
Queueing systems (QS) are considered in which the waiting times are limited, whereas the times of service and of readjustment of the units depend on the modes of service. Sufficient optimality conditions are obtained for a QS consisting of two units. A multiunit QS can be optimized by a combined branch-and-bound method with sequential analysis and shifting of versions.
