Abstract
Applications of discrete mathematical programming may be subdivided into those involving economies of scale, those involving mutually exclusive variables and those involving nonconvexity in the constraint set. Exxon’s earliest successful applications involved investment planning under economies of scale. Operations scheduling applications are characterized by mutually exclusive variables: these have been solved satisfactorily by heuristic methods and by branch-and-bound methods running under stream-lined computational procedures. Nonconvex constraints are found in engineering design problems: these require artful formulation and specialized computational search procedures. Research is still needed to endow discrete mathematical programming with interactive computation capabilities, with enhanced analytical and interpretive options and with extensions into the domain of mathematical programming under uncertainty.
