基于两级信用支付和合作策略的EPQ模型

Integrated Supplier-retailer Cooperative EPQ Model under Two Levels of Trade Credit

信用支付策略的设计直接影响到整个供应链的收益。基于两级信用支付,研究了供应商和零售商采取合作策略的EPQ模型,并通过分析不同情况下的收益函数,提出了使供应商和零售商总收益最大化的最优销售价格和最优信用期长度的帕累托最优解的求解算法。最后通过算例和灵敏度分析进行了验证,分析并揭示了最终需求和利息率对最优销售价格和最优信用期长度的影响。

The trade credit policy model that incorporates the concept of design has influenced the profits of the whole supply chain. A new EPQ the integrated supplier-retailer cooperation and two levels of trade credit is developed. Then a procedure for characterizing Pareto efficient solutions of the optimal unit price and the length of the credit period is provided to maxmize the profits of the whole supply chain by analysing the profits functions of the retailer and the supplier. Finally, examples and numerical analysis are given to analyse the effect of the end demand and the interest rate on the the optimal unit price and the optimal credit period.
