Abstract
This research aims to determine the optimal ordering period for multiple products. There are three policies: individual ordering policy, joint ordering policy, and mixed ordering policy. The study of the current system found the lowest average operation cost of 16,521.01 baht per day. The most optimal policy research results are individual ordering policy has the lowest average operation cost of 15,321.18 baht per day. This reduces expenses by 1,199.83 baht per day or 7.26 percent.
