Abstract: Supplier selection and related issues are among the most important decisions in the area of Supply Chain Management. A few of papers and studies have considered the major decisions related to supplier selection with non-crisp data. This paper comes across with a novel approach to the problem by presenting an integrated framework which involves two stages: suppliers| evaluation and order allocation. In this way, for suppliers| evaluation, a Fuzzy Data Envelopment Analysis (Fuzzy DEA) model is conducted and then a multi-objective integer programming with fuzzy objectives and fuzzy constraints is formulated to assign an optimal quantity of orders to suppliers.

Keywords: supplier evaluation; order allocation; fuzzy DEA; data envelopment analysis; fuzzy linear programming; non-crisp environments; SCM; supply chain management; multi-objective integer programming; fuzzy objectives; fuzzy constraints; optimal order quantities; logistics systems management; integrated frameworks.
