Abstract
In competitive global markets, sustainable suppliers are critical success factors for sustainable supply chain operations. Sustainable supplier selection must be based on a complex network of numerous indicators and experts’ fuzzy linguistic terms. Considering the correlation between the evaluation criteria and the ambiguity of the criteria values, this paper proposes combining the rough DEMATEL method and the fuzzy VIKOR (FVIKOR) method to solve sustainable supplier selection problem. We determine 15 sustainable supplier evaluation criteria from economic, environmental and social dimensions. We also apply the rough DEMATEL method to determine the weight of evaluation indicators that are interrelated or even conflicting and use the FVIKOR method to determine supplier rankings by converting the fuzzy linguistic terms into precise information. The practicability of the proposed method is verified by an example of sustainable supplier selection.
Highlights
In competitive global markets, the supply chain of multiple relationships between upstream suppliers and downstream producers constitutes a new type of economic organization because it generates a fusion effect of core competences and resources from different organizations
Many studies have confirmed that the green supplier evaluation index system considered only traditional and green criteria and ignored social criteria when it was established
As a growing number of experts begin to concentrate on the issue of sustainable supplier evaluation selection, social criteria were gradually included in the consideration of the supplier evaluation index system
Summary
The supply chain of multiple relationships between upstream suppliers and downstream producers constitutes a new type of economic organization because it generates a fusion effect of core competences and resources from different organizations. Sustainable suppliers are critical success factors for sustainable supply chain operations [1]. It is difficult for a separate organization, especially a downstream producer, to survive by depending on its own power [2]. Companies in developed countries must use the optimal measures to select multinational suppliers according to the economic and environmental objectives [4]. Multinational companies incorporated environmental protection and resource-saving consciousness into supplier management, and scholars focused on researching supplier evaluation of green procurement from different perspectives. In truth, multinational companies have to abandon incompetent suppliers who have difficulty meeting or exceeding green expectations due to limitations
