Optimal Decisions in a Supply Chain with Different Suppliers' Price-setting Power and Manufacturers' Competition Structures1

摘要

In this paper,we focus our analysis on optimal decision models in an assembly supply chain consisting of multiple suppliers and multiple manufacturers.We examine the optimal pricing models in four different suppliers' price-setting power structures under two types of manufacturers' competition structures (independent competition and Stacklberg competition) and investigate the impact of suppliers' price-setting power structures on supply chain by performing comparison analysis.Our analysis shows that the optimal retail price (the optimal production quantity) in the centralized supply chain is lower (larger) than those in all three decentralized supply chains.In three decentralized supply chains,our analysis shows that the production quantity,supply chain profit,manufacturers' profit and suppliers' profit (the supplier's spare parts wholesale prices) when suppliers are integrated are larger (lower) than those when suppliers are independent,the production quantity,supply chain profit,manufacturers' profit and suppliers' profit (the supplier's spare parts wholesale prices) when suppliers are-independent are larger (lower) than those when suppliers are unequal with a Stackelberg leader.
