Abstract

These two papers examine the challenges of selecting sustainable suppliers in the supply chain, particularly in the construction and electronics industries. Both studies emphasize the importance of a multi-criteria decision-making (MCDM) approach due to the complexity of these decisions. Both papers use a combination of Analytic Hierarchy Process (AHP) to weight criteria and TOPSIS to rank suppliers.

The first paper focuses specifically on social sustainability in the construction industry and seeks to identify and weight key social criteria by interviewing experts and using AHP and TOPSIS. It aims to provide an MCDM model for construction organizations to improve the social sustainability of projects. The second paper examines the different dimensions of sustainability in the electronics industry and evaluates four dimensions: economic, social, environmental and ethical and 16 sub-criteria. The aim of this study is to provide a comprehensive and practical model for selecting sustainable suppliers in this industry.

In both papers, the AHP method is used to determine the relative weight of the criteria and TOPSIS is used to evaluate suppliers based on these criteria. The results show that although economic factors are of great importance in selecting sustainable suppliers, other sustainability criteria such as human rights, occupational health and safety, pollution control, financial transparency, and social criteria should also be considered. These two studies propose MCDM computational models as an effective tool to help companies select sustainable suppliers in their supply chains.
