Abstract

UD. X is a company engaged in the business of selling bike, child equipment, and toys in Banjarmasin, South Borneo. UD. X is only able to meet 70% to 80% of consumer demand. Overstock and understock often occurs due to ordering by estimates based on experience. The procurement policy that is used is Periodic Review Policy that consists of S,T Policy, and s,S Policy. The service level used in this policies is 99,99%. All policies will be simulated and compared with the current policy. The simulation is run for 5 products. Simulation result shows that in comparison with the current policy, s,S Policy can decrease the cost for all products while S,T Policy can only decrease the cost of three products. The result of 5 years simulation for the two policies shows that s,S policies is better than S,T Policy for two products, but not significantly different for the other products. This result shows that in the long run s,S Policy can be better than S,T Policy.
