| Abstract | A retailer, a main supplier and backup supplier were examined in this proposed system. The two suppliers were considered under two separate contracts. Under a quantity flexibility contract, the main supplier was used, while the backup supplier was used under a range contract. It was stated that the main supplier was vulnerable to disruption and, as such, this contract configuration was proposed to minimize the impact of the stated disruption. A mathematical model was designed to simulate the mentioned system in this report. Using the statistical model, experiments were conducted using MA TLAB to obtain the optimal order quantities for the retailer from the main supplier and the backup supplier to get optimal profit for him. A sensitivity analysis was also carried out to examine the impact on the order quantities of changing range fees, shortage price and penalty fee. Furthermore, to determine the efficiency of this contract configuration, a comparison was made between both the centralized and decentralized systems. The effect of the return quantity ratio is unclear, and it can be concluded that this contract configuration can coordinate the supply system. |
