近年来，公司开始关注其供应链，以提高其可持续发展绩效，以满足客户需求并遵守环境法规。因此，可持续发展意识已成为供应链管理中的一个重要问题，企业更愿意与其他专注于这一主题的公司合作。本研究提出一个可持续供应商选择与订单分配的决策架构。该框架由三个组成部分组成。首先，模糊决策试验和评估实验室（DEMATEL）的方法被用来计算决策过程中考虑的可持续性标准的权重。其次，这些权重被用作田口损失函数的输入，用于对每个供应商的评级值进行排名和计算。然后将排序值作为输入，使用双目标优化来确定应分配给每个供应商的最佳订单数量。本研究的第一个贡献是，它提出了一种新的混合方法，通过集成模糊DEMATEL和田口损失函数的可持续供应商的评估和排名。第二个贡献是在文献中首次提出了一个新的双目标模型，该模型考虑了订单分配阶段的销售损失问题。所提出的框架的说明上的案例研究，帮助决策者选择可持续的供应商，并考虑到损失的销售确定订单规模。(C)2018爱思唯尔有限公司版权所有
In recent years, companies have started to focus on their supply chains to enhance their sustainability performance in order to meet the customer demands and comply with environmental legislations. Therefore, the sustainability awareness has become an important issue in supply chain management and companies prefer to work with other companies focusing on this subject. This study presents a decision framework for sustainable supplier selection and order allocation problem. The framework consists of three integrated components. First, fuzzy Decision Making Trial and Evaluation Laboratory (DEMATEL) approach is used to calculate the weights of sustainable criteria considered in decision making process. Second, these weights are used as inputs in Taguchi Loss Functions for ranking and calculating the rating value of each supplier. The ranking values are then taken as inputs to determine the optimal order quantities that should be allocated to each supplier using bi-objective optimization. The first contribution of this study is that it presents a novel hybrid approach by integrating fuzzy DEMATEL and Taguchi loss functions for evaluating and ranking sustainable suppliers. The second contribution is that a new bi-objective model considering the issue of lost sales has been proposed for order allocation phase for the first time in literature. The illustration of the proposed framework is shown on a case study which helps decision makers to select the sustainable suppliers and determine order sizes considering lost sales.
