A new mathematical approach for suppliers selection: Accounting for non-homogeneity is important

摘要

The assumption of classical supplier selection models is based on complete homogeneity of suppliers. In spite of this assumption in many applications some suppliers do not comprehensively consume common inputs to comprehensively supply common outputs. The objective of this paper is to propose an innovative method for selecting slightly non-homogeneous suppliers. A numerical example demonstrates the application of the proposed method.
