供应链中商业信用与订货批量协调决策

摘要

Commercial credit, economic quantity, revenue sharing, supply chain management. Based on different commercial credit strategy assumes provided by supplier, this paper study joint lot decision problem in two-level supply chain consist of a single supplier and a single retailer. On the basis of analysis of existing literature and sort, we think length of the commercial credit as decision variables and consider the circumstances that suppliers may enlarge procurement as an integer multiple by order quantity of retailers in each cycle. Thus, we construct optimal lot decision model under different strategies of suppliers and integrated cost model of supply chain. In addition, we provide income distribution program about cost savings in supply chain. The results show that order quantities of retailers will be higher and the overall cost of the supply chain will be lower when suppliers provide incentives of commercial credit, compared with the case that suppliers don't provide incentives of commercial credit. Finally, some numerical examples are used to illustrate the results obtained in this paper.%文章基于供应商提供的不同商业信用策略假设，研究了由单一供应商和单一零售商构成的二级供应链中的联合批量决策问题。文章在对现有文献进行分析和梳理的基础上，将商业信用期长度作为决策变量，并考虑每循环周期供应商可能按照零售商订货量的整数倍放大采购的情形，构建出供应商不同商业信用策略下供应商和零售商的最优批量决策模型和供应链综合成本决策模型，并给出了供应链成本节约的收益分配方案。结果表明，与不提供商业信用激励相比，供应商提供商业信用激励时零售商的订购批量会更高，供应链的综合成本也更低。考虑到供应链联合决策中可能出现的收益不均衡问题，文章提出针对供应链协同带来的成本节约，按供应商与零售商投入存货成本比例进行分配的收益共享决策方案。最后，文章通过算例验证了模型和算法的有效性。
