VAGUELY INTERRELATED COEFFICIENTS IN LP AS A BICRITERIAL OPTIMIZATION PROBLEM

This paper deals with linear programming problems with fuzzy coefficients. Moreover, relations between coefficients are considered and these relations are expressed by membership functions. The problem has two goals: 1. to choose the coefficients with the highest membership grades of interrelations, and 2. to maximize the orginal objective function of the LP problem. An interactive procedure based on the successive solutions of LP problems is proposed.
