Abstract: Supplier selection is important strategic decision for agrifood supply chain management. This decision problem is frequently complex and unstructured. This paper aim presents a Delphi-AHP-TOPSIS framework for supplier selection problem. The making-decision methodology has been divided into three steps. Firstly, Delphi method is used to identify the main criteria and sub-criteria for the evaluation process. Secondly, analytic hierarchy process (AHP), where the evaluation of criteria is applied in order to prioritise each criterion based to expert's judgements. Thirdly, the technique for order preference by similarity to ideal solution (TOPSIS) has been used to rank the alternatives for final decision. Finally, in order to clarify the use of proposed combined method, a numerical example was applied to select supplier on Algerian tomato processing company. The analyses of the results have shown that the proposed framework is an appropriate tool for the problem of supplier selection.
