By focusing on reducing the time and eliminating waste for the purchasing process. The study takes the first phase with studying workflow of each process in order to provide existing situation model, examine workflow in each stage of activity to identify for wastefulness in each process, find resolution for solving problem to increase efficiency by using ECRS then provide future simulation model in order to compare the result between the process before and after improvement using ARENA simulation software. After the improvement, the result of this research found that the lead time is reduced by 46.70% and the number of purchasing process is decreased by 9.76%.
