本文提出了一个模糊系统下包含单一供应商、单一制造商和单一批发商的三层供应链模型。考虑了三种情况：(A)员工对生产成本的学习效应(LE)以及供应商与外部供应商之间以及制造商与批发商之间的退货合同(RC)；(B)不考虑制造费用的学习效应(LE)；(C)SC参与者之间没有RC。本文的目的是研究在集中式和分散式两种情况下，LE和RC对供应链总利润的影响。为了适应整个流程需求参数的灵活性，我们建立了所提出的供应链问题的模糊数学模型。为了讨论该模型的新颖性，我们插入了一张作者贡献表，并借助LINGO软件进行了数值说明，并将现有方法的最优结果与提出的模糊方法进行了比较研究。为了更好地实现模型，还进行了敏感性分析和图形说明，并得出了结论。
This article presents a three-echelon supply chain (SC) model, incorporating a single supplier, a single manufacturer, and a single wholesaler under fuzzy system. Three scenarios have been considered: (a) the learning effect (LE) of the employees on the production cost as well as the return contract (RC) between the supplier and an outside supplier and also between the manufacturer and the wholesaler, (b) without considering the LE on the manufacturing expenses and (c) without the RC between the SC players. The goal of this paper is to study the effect of the LE and the RC on total profit of the SC for centralised and decentralised cases. To adopt flexibility of the demand parameters of the entire process, we develop a fuzzy mathematical model of the proposed SC problem. To discuss the novelty of the proposed model, we insert a table of authors' contribution and also perform numerical illustrations with the help of LINGO software and make a comparative study between the optimal results of the existing method and the proposed fuzzy approach. Sensitivity analysis and graphical illustrations have also been done for better realisation of the model followed by conclusion.
