关闭现有的现实世界供应链并对由此产生的网络进行建模是具有挑战性的实践。本文研究了纺织企业关闭供应链的可能性及其对供应链利润的影响。本文讨论了逆向链收益率建模中的一个常见问题。由于在估计这样的利率不准确导致不正确的结果，本模型放弃了常用的预定利率，提出了一个有条件的质量为基础的分割政策的需要。增加二级链作为回收选项，质量依赖的激励率和灵活性的模型在定义质量，也是本文的新颖点。首先，提出了一个双目标模型来制定链，其中包括制造商，分销商和客户的前向链和再制造，维修和回收中心的后向链。此模式适用于已推行零废物策略及设有类似回收设施的行业。其次，对纺织行业的一个案例进行了广泛的敏感性分析。结果表明，低/中等质量的回报率的增加导致更高的利润，因为他们创造了更合适的环境/经济的商业机会。此外，关闭公司的供应链增加了分销商/收藏家的业绩对最终利润的影响。因此，公司的管理者需要采取有利于分销商/回收商的定价政策，这相当于降低制造商的维修，再制造和采购成本，并提高对客户，制造商和回收中心的销售价格。
Closing an existing real-world supply chain and modelling the resultant network are challenging practices. This paper investigates the possibility of closing the chain in a textile company and the effects of such a decision on the profits of the chain. The paper addresses one of the common problems in modelling the return rates of backward chain. Since inaccuracy in estimation of such rates leads to incorrect results, the present model forgoes the need for commonly used predetermined rates by proposing a conditional quality-based segmentation policy. Addition of a secondary chain as a recovery option, quality-dependent incentive rates and flexibility of the model in defining quality, are also among novel points of this paper. First, a bi-objective model is proposed to formulate the chain which includes the manufacturers, distributors and customers in the forward chain and remanufacturing, repairing and recycling centers in the backward chain. This model is applicable to industries with zero-waste strategy and similar recovery facilities. Second, an extensive sensitivity analysis is carried out on a case-study from textile industry. The results reveal that increase in rate of returns with low/medium qualities leads to higher profits since they create more suitable environmental/economical business opportunities. Moreover, closing the supply chain of the company increases the impact of distributors/collectors’ performance on the final profits. Hence, managers of the company need to adopt a pricing policy in favor of the distributors/collectors, which equals to lower repairing, remanufacturing and purchase costs from manufacturers, and higher sales prices to customers, manufacturers and recycling center.
