摘要
为研究供应链结构对供应链绩效的影响,构建了两级装配系统中质量投资与价格决策模型。分析了3种不同决策序列的纳什均衡,并从各参与方的角度讨论了其最优决策序列,即供应商先同时进行质量决策后再同时进行批发价格决策、供应商同时进行质量决策和批发价格决策以及供应商1先进行质量和批发价格决策。研究发现,集中决策优于独立决策,且价格敏感系数越低、质量敏感系数越高集中决策的优势越显著;第1种决策序列下供应链总利润最高;第2种决策序列是制造商的占优策略,但是供应商1的最差策略;第3种决策序列下供应商2的利润最低。
To study the impact of supply chain structure on supply chain performance, decision models with product price and quality investment are proposed. Equilibrium solutions under decentral- ized decision models with three different decision sequences are analyzed, and the optimal decision se- quences from each firms perspective are also discussed. In the first decision sequence, two suppliers invest in the technology to improve their component quality independently and simultaneously, and then set the wholesale price for their components simultaneously. In the second decision sequence, two suppliers decide quality and wholesale price for their component independently and simultaneous- ly. In the third decision sequence, supplier 1 as the leader first decides quality and wholesale price for component 1, supplier 2 follows supplier 1 to make his decision. Results show that centralized deci- sion is better than decentralized decision, and advantages of centralized decision are more outstanding when coefficient of price-sensitive is low and quality-sensitive is high. It also shows that the whole supply chain can achieve the highest profit under the first decision sequence, the second decision se- quence is a dominating decision sequence for the manufacture which is the worst option for supplier 1, and the third decision sequence is the worst option for supplier 2.
