This research has studied by using two methods in order to choose the best suppleirs. These are Analitical Hierarchy Process (AHP) and Fuzzy AHP. This research has also studied to fulfill the optimal raw material order. In order to get the optimal order quantity, this research suggested Economic Order Quantity (EOQ) modeling. This research has shown that there are no significant deferences between AHP and Fuzzy AHP. Based on this research, PT. XYZ may use either AHP or Fuzzy AHP to choose the best supplier. Based on EOQ, the optimal order quantity is 103.730kg, and company should order every 23 days, meaning there is 16 times order to supplier. The reorder point is 22.230kg, and the total cost is Rp.9.923.475.086.
