AN INTERACTIVE DECISION FRAMEWORK FOR MULTIPLE-OBJECTIVE PRODUCTION PLANNING

The formation of realistic implementable medium-range production plans requires explicit recognition of the multiple conflicting objectives of production planning. However, suggested applications of multiobject ive optimization to production planning have been limited to goal prog ramming procedures which fail to capitalize on the intrinsic flexibili ty of a multiobjective model. Alternatively, interactive multiobjectiv e solution techniques could be used to allow planners to enhance decis ion making without excessive computational effort. This study describe s an interactive multiple objective decision framework and evaluates i ts effectiveness via a multiobjective capacitated lot sizing model bas ed on a real manufacturing facility. The results suggest that this app roach is an effective solution strategy and useful decision aid for co mplex production planning problems.
