A state entropy model integrated with BSC and ANP for supplier evaluation and selection

This paper proposed a new method for supplier evaluation and selection after analysing the supplier state evolutionary process according to the entropy change process in the thermodynamics. In order to verify the feasibility of the new proposed method, we applied it to a maintenance, repair and overhaul/operation enterprise. Besides, we analysed the characteristics and problems of the maintenance, repair and overhaul/operation industry firstly, and then established an index system and calculated weights by balanced scorecard and analytic network process respectively. The results calculated by the proposed method are proved to be in accordance with the reality.
