Modeling to Generate Alternatives: A Review

Abstract:

Modeling to generate alternatives (MGA) is a species of multiobjective programming in which some relevant objectives and perhaps some constraints are deliberately left unquantified. The aim of MGA is to present to the decision maker(s) a set of alternative solutions that are optimal or nearly optimal in single objective formulations or noninferior or nearly noninferior in multiobjective formulations. The results of MGA are a set of alternative solutions, called the presentation set; these solutions are few in number, good with respect to the modeled objective(s), and significantly different from each other. The techniques of MGA include one-phase techniques in which the generation of alternatives and the selection of the presentation set are simultaneous, and two-phase techniques in which a large number of alternatives is generated and then a subset of them is selected for presentation to the decision maker(s).
