Supply chain management is a process of planning, implementation and control of operations that includes all shifts and store raw materials, inventory and finished product from the initial starting point to end point of consumption is. This paper investigates integrate of two basic subjects routing vehicles and reduce maintenance costs of materials and products in the form of a programming model in which dataare considered as fuzzy numbers. Uncertainty of system may be induced from uncertainty of the process loading, discharge, and amount of consumption and the consumption rate. In such an uncertain environment, trying to make decision without using mathematical programming is led to irreversible or irrelevant decisions. Therefore, the fuzzy decisions model is recommended in the proposed model forplanning.
