Abstract: In this paper, we focus on the supplier selection in a global context. The main features that characterise the global supplier selection are first identified. They mainly include the necessity of integrating inventory and transportation issues and considering several buyers| sites. We then show that supplier selection models that simultaneously consider all these features are missing in the literature. Hence, we propose a two-phase global supplier selection approach: a first pre-selection phase with a scoring method and a final selection phase using a mathematical optimisation model. Finally, we perform different computational experiments based on a case study in order to illustrate the consistency of the model and to analyse some relevant managerial situations such as those related to the selection of low-cost suppliers.
