Lot sizing method used by distributors and outlets only on half of the average for the past six months and the determination of safety stock and a half from the previous demand. As a result, distributors and outlets set the number of reservations lot more volatile than demand. Lotting method applied early distributors and outlets can lead to the phenomenon of the bullwhip effect and storage of goods in warehouses or too much stock out. The main objective of this study is to propose improvements to methods of lot size on the distributor and the outlet, so as to reduce the value of the bullwhip effect and the total cost of inventory. By using the concept of lot sizing method, it will get the value of the bullwhip effect and the total cost of inventory is lower than the initial lotting method that has been used distributors and outlets. The stages of this research is to study early to know the real situation in the company and to identify problems, then performed the data collection. After that stage bullwhip effect measurements and total cost of inventory at the beginning of lotting method. To determine the appropriate method of lot size, then the plan calculation method of booking through lot size EOQ, POQ, LUC, and SM. Then do the calculation of the total cost of inventory and the value bullwip on alternative methods of lot size. At this stage of the analysis and the proposed method of determining lot size, lot size method chosen by the first indicator, the value of BE and the second total inventory costs. From the data processing stage known BE values obtained from the smallest lot size EOQ and POQ the distributor outlets. Of the two methods of lot size is produced minimal inventory cost of the method of initial lot size. The proposed method of determining the lot size is the determination of the reservation will affect the value of lot bullwhip and inventory costs.
