Selecting suppliers is a multi-criteria decision-making problem involving both qualitative and quantitative factors. The aim of this paper is to propose a multi-criteria approach that aids to select suppliers based on two interrelated inputs: overall system performance and supplier performance. With this model, enterprises that are collaborating will have a tool to select suppliers not only based on supplier performance but also aligned with their own strategy increasing the quality of the supplier selection process and, therefore, improving the sustainability of the partnership and their competitiveness.
