Risk pooling through lateral transshipment has been proven as an effective logic to improve material supply and to reduce total system costs. The purpose of the study is to analyze transshipment strategy using simulation techniques with different lead times of material supply. A central warehouse with multiple manufactures is analyzed in the research. To eliminate imminent shortage, materials are transshipped from manufacturing plants that have sufficient supplies to the others that starve for materials. Strategies for deploying materials including priority and quantity are investigated. Three scenarios with different material lead times, demands, transportation costs, and tardiness penalties are studied. Simulation results show that TBAPRI is the most profitable transshipment strategy to improve material shortage and system costs. In addition, the research identifies that pooling risk through lateral transshipment is not advantageous when transportation cost is much higher than tardiness penalty.
