Abstract:
Green supply chain management (GSCM) is crucial for environmental compliance and business development of companies. Companies look for new ideas and methods to achieve environmental sustainability. GSCM is an innovative idea which involves all business value-adding operations, such as purchasing and in-bound logistics, production and manufacturing, distribution, out-bound logistics, and collaboration with patrons and suppliers with the minimum negative environmental impact. The main purpose of the present study was to find the interrelationship between green supplier criteria applying a novel model. Thus, experts’ opinions were investigated through nominal group technique (NGT) to understand the interrelationship and causal preferences of the green supplier evaluation aspects through Fuzzy Decision-Making Trial and Evaluation Laboratory (DEMATEL) method. The degree of importance factors shows that environmental performance is a proper index for displaying companies adopting their supply chain into the GSCM as the third most important criterion. The results of the priority weight analysis of the criteria demonstrated that the production Capability has minimal impact on GSCM adoption. The findings also revealed that the production capability falls under the effect group, and green design and production capability are correlated.
Machine summary:
Thus, experts‘ opinions were investigated through nominal group technique (NGT) to understand the interrelationship and causal preferences of the green supplier evaluation aspects through Fuzzy Decision-Making Trial and Evaluation Laboratory (DEMATEL) method.
The Analytic Network Supplier Evaluation Model for GSC in this study proposes that the supplier evaluation criteria include five dimensions: competitive pricing and cost, reliability, production capability, environmental performance, and pollution control.
In this stage, the evaluation criteria for GSs are collected (2006) implemented dynamic fuzzy membership functions to assess environmental performance in the process of supplier selection.
(2007) proposed a multi-objective decision analysis to apply environmental tenets to evaluate green supplier at different supply chain levels.
This research developed a conceptual model for GS evaluation, applying DEMATEL for adaption of uncertainties and complexities in the real world, assisting SC managers and organizations to find a proper tool for evaluation and controlling GSs via various Step 1: Making the direct-influenced matrix Finding direct-relation (average) matrix; there are five scales which determine values of relationships between various factors based on expert opinion.
Also to compare each of the five criteria of verbal expression is used which the terms and amounts shown in Table (1) equivalents phase: through literature review and discussion with managers in an industry and eco-experts with NGT according to the evaluation model of analytic network supplier for GSC (Figure 1).
