SIMULATION OF MATERIALS INVENTORY IN A MANUFACTURING PLANT WITH WORLD-WIDE SUPPLIERS AND CUSTOMERS

摘要

The goal of this project was to develop an inventory computer model to better understand the effect of demand variation and lead times on inventory turnover in a manufacturing plant. In this particular situation, the manufacturing plant was located in Asia, with suppliers in Japan, and the United States while the customer was in Australia. The computer model was developed using the AweSim simulation software, with input in the form of customer forecasts from Excel. The output from the model shows the level of RM, WIP, and FG inventory in terms of the number of units, the value of the units, and the days of inventory on hand over a 52 week period, both as static and dynamic output. The user is free to change the forecasts, lead times, or costs to see the effect on inventory.
