一类数量折扣新形式的设计:模糊两级供应链的完美协调

针对市场模糊需求,考虑了由一个供应商和一个销售商组成的两级供应链系统。以供应商为第一视角,构建了一类新的数量折扣形式,并研究了其在分散决策下如何制定数量折扣,使供应链避免"双边际化"效应,实现系统完美协调。基于可信性理论,给出了LR型模糊变量期望值计算式。利用模糊期望利润函数,得到了实现供应链完美协调的条件。数值分析证明了该形式数量折扣的有效性。

Design of New Form of Numerical Discounts:Perfect Coordination of Fuzzy Two-echelon Supply Chains

In this paper,from the perspective of the supplier,we established a new form of numerical discounts,studied how to determine the numerical discounts under discrete decision-making to avoid bi-lateral marginalization and realize perfect coordination.On the basis of trust theory,we gave the calculation equation for the expected value of the LR fuzzy parameter and then,a step further,obtained the condition for perfect supply chain coordination.Finally,a numerical analysis proved the effectiveness of this form of numerical discounts.
