The problem of optimizing the expected performance of a discrete-event, stochastic system was studied. The study proposed an optimization-via-simulation algorithm for solving the stochastic, discrete-event simulation problem. The decision variables of the system were such that they might be subjected to the deterministic linear integer constraints. The proposed approach, which consisted of a global guidance system, a selection-of-the-best procedure, and local improvement method, was globally convergent under mild conditions.
