Inventories typically consist of at least two categories of items, the first being the major part of the inventory's value, usually not large, and the second being the lesser part of the inventory's value and the number of items Far more than the first batch. Therefore, using a single inventory control method for all of these items does not seem reasonable. In the ABC inventory control system, most attention is focused on the upper class items and the subsequent classes are less important. In this study, according to ABC method 77 items of raw materials were divided into three groups, 11 of which were classified as commodity A, 16 items in category B, and 50 items in category C. Following the criteria of consumption, scarcity and criticality of items, using ABC method and fuzzy classification were used to classify 77 items and it was found that 14 items were very important, 20 items were important and 43 items were in the group. They are not important. Since lack of or in the absence of raw materials in the market can cause problems for manufacturing units, accurate identification of the goods in these three groups can be helpful in planning the purchasing and inventory control system of the companies considering the quality criteria.
