基于收益分享契约的创新性产品供应链研发投入决策模型

R D investment decision model of innovative product supply chain based on revenue-sharing contract

摘要:

创新性产品研发需要供应链成员之间的良好合作,现有研究较少讨论供应链成员在研发投入决策方面的竞争与合作问题。本文引入了与研发投入相关的研发成本函数和研发成功概率,分析了集成供应链的最优决策。建立了一个离散供应链中零售商与作为研发主体的供应商之间收益分享竞争模型,分析其均衡解。在此基础上,讨论了目标研发投入水平奖励契约,实现在了协调供应链的同时,在成员之间任意分配期望收益。

Abstract:

R D of innovative products needs tight cooperation between the members of the supply chain. Current works seldom discuss the competition and collaboration in R D investment between the supply chain members. The paper introduces the R D cost function and the probability of R D success. The integrated supply chain’s optimal R D investment decisions are gained. Then the paper constructs a revenue-sharing competition model between the retailer and the supplier who is charge of R D investment decisions. The competition equilibrium solutions are analyzed. Based on above discussion, a reward contract with an investment target is introduced. After reasonable contract design, the supply chain can be coordinated and arbitrarily revenue allocated between the members synchronously.
