Abstract

There are numerous uncertainty forms and modes capable of affecting the Material requirements planning (MRP) systems. The aim of this study was to provide a fuzzy multi-objective decision-making model for MRP problem. In this paper, a fuzzy multi-objective linear programming approach was proposed for MRP model with a fuzzy Lead Time (LT), in which, the MRP models of classic numbers were combined up to the probability of occurrence of each of the possible LTs as far as possible. Then, an objective function was considered, which maximizes the probability of occurrence of LTs. The initial values ​​of the MRP model were applied to this objective function and some decision makers were shown that with their risky behavior accept some LTs, which improve other goals, but their probability of occurrence is poor.
