根据传统的供应链协调契约,提出了“收益共享+剩余”契约(RS)和“批发价格+回购”契约(WB)两种混合契约机制。引入了金融中测量风险的条件风险值(CVaR)来研究由具有风险规避行为的两个供应商和一个装配商组成的装配系统的协调问题。分别探讨了在两种契约下,风险规避水平对供应商生产量/发货量和装配商订货量的影响,以及如何制定共享比例和批发价格等参数,得出了装配系统最优的生产量/发货量和订货量,以及使装配系统达到协调的条件。
According to the traditional supply chain coordination contract, two hybrid contract mechanisms, “Revenue Sharing + Remaining” (RS) and “Wholesale Price + Repo (Contract)” are put forward. The CVaR of risk measurement in finance was introduced to investigate the coordination of assembly systems consisting of two suppliers with risk aversion and one assembler. The effects of risk aversion level on supplier throughput / shipments and assembler order quantity under two kinds of contracts are explored separately, and how to set parameters such as share ratio and wholesale price, and the optimal throughput of assembly system is obtained / Shipments and order quantities, and conditions for the assembly system to be coordinated.
