| Summary: | 碩士 === 義守大學 === 工業工程與管理學系碩士班 === 93 === The impact of global competition has shortened the product lift cycle and caused the supply chain management (SCM) become an increasingly growing business improvement issue. Collaboration between SCM partners is a good solution to gain an advantageous competition position, and it can be achieved by supply chain contracts.
The purpose of the research is to analyze the performance of centralized and decentralized supply chain contracts of the products with one period property. The decentralized supply chain contracts considered in the research are buy-back contracts and revenue sharing contracts. The 2-tier supply chain (SC) including a manufacturer and a retailer is analyzed under different contracts.
Theoretically, the expected profit of the decentralized contract, whose performance depends on the uncertain market demand which has price elasticity, can be equal to the profit of the centralized contract. The maximum profit of the SC when using the buy-back contract makes all the profit belongs to the manufacturer. On the other hand, the optimal solution of the revenue sharing contract lets the retailer gain the total profit of the SC. Therefore, the ideal profit distribution of the SC in practical environment is subject to the constraint provided by one of the SC partner.
Finally, compared the two decentralized models, we found that the buy-back contract has good performance if the manufacturer can get the higher profit. In other words, the buy-back contract is suitable for the manufacturer which is powerful in the supply chain. On the contrary, the SC that adopts the revenue sharing contract would have more profit if the retailer is more powerful than the manufacturer.
