Interactive partitioning criteria set method for multiple objective linear programming

This paper develops an interactive method for multiple objective linear programming problems. The decision maker’s capability to evaluate the trade-off vector is affected by the number of criteria involved in the trade-off vector. In this paper, the problem considered has too many criteria for the decision maker to properly evaluate the trade-off vector when all the criteria are considered simultaneously. Hence partitioning of the criteria set is recommended to facilitate easier interaction with the decision maker. A linear additive utility function is assumed.
