Integration of sustainable development in the business and supply chain is potentially asource of competitive differentiation for firms. Academic and corporate interest insustainable supply chain management (SCM) has also risen considerably in recentyears. Sustainable SCM is the management of material, information and capital flows aswell as cooperation among companies along the SC while taking goals from all threedimensions of sustainable development, i.e., economic, environmental and social, intoaccount which are derived from customer and stakeholder requirements. This paperexamines the components and elements of sustainable SCM and how they serve as afoundation for an evaluation framework. By using the quality function deployment(QFD) as a product or process development tool, an effective sustainable SCM structurecan be obtained. The traditional QFD structure requires individuals to express theirpreferences in a specific scale. However in practice, people contributing to the processgenerally tend to give information about their personal preferences linguistically andeven incompletely, depending on their background. Therefore, the objective of thisstudy is to apply an extended QFD methodology in sustainable SCM by introducing anew group decision making (GDM) approach that takes incomplete preference relationsinto account, and fuses different preferences into one uniform group decision by meansof fuzzy set theory. This methodology is compatible with the requirements of thevarious stakeholders involved in the SC. To assess the validity of the proposedapproach, applications in two specific companies are given.
