MCDA-based approach to sustainable supplier selection

The process of sustainable supplier selection is crucial to a company's business continuity. Distortions in poorly chosen suppliers can lead to an impediment or even complete downtime of the company's operations. The paper proposes a new unique approach in which classical MCDA paradigm is extended with aspects of temporal evaluation and various temporal aggregation strategies are provided. The partial MCDA evaluations are performed with three MCDA methods -- AHP, TOPSIS and COMET -- to allow for hierarchical structuring of the decision problem, creation of a reference model and avoiding rank reversal. The proposed approach is verified on a case study with an actual company and its supplier selection from a group of 30 potential suppliers.
