An Approach to Solve Multi-objective Linear Production Planning Games with Fuzzy Parameters

In this research, the n-person cooperative games arising from multi-objective linear production planning problem with fuzzy parameters are considered. It is assumed that the fuzzy parameters are fuzzy numbers. The fuzzy multi-objective game problem is transformed into a single-objective game problem by group AHP method. The obtained problem is converted to a problem with interval parameters by considering the near- est interval approximation of the fuzzy numbers. Then, optimistic and pessimistic core concepts are introduced. The payoff vectors of the players are obtained by the duality theorem of linear programming. Finally, validity and applicability of the method are illustrated by a practical example.
