Inventory planning is done very simply by forecasting based on sales history data at PT KTS to retail, causing a buildup of finished goods in the central warehouse. PT KTS forecasts demand based on retail demand not based on final customer demand to retail. Inventories made are not based on sales to final consumers, resulting in a bullwhip effect. The method used is by applying the Distribution Requirement Planning (DRP), the goal is to calculate the value of BE at PT KTS, BE after DRP and make an order plan based on DRP.
