Supplier Selection Modeling and Analysis Based on Polychromatic Sets
نویسندگان
چکیده
The competition in 21 century is no longer located among enterprises, but in all the supply chains. To maximize the supply chain benefit, the stable and efficient supply chain should be provided. This paper applies the polychromatic sets to discuss the supplier selection problem and describe the supplier selection related factors. According to those factors, a model is illustrated in detail by means of sets and graphic in the polychromatic sets. The model uses adjacent matrix and contour to modify supplier selection factors. A procedure of selecting suppliers is presented to identify and find competitive suppliers. Then the model is optimized by using genetic algorithm. At the end, a case is provided to show that the methods are effective to select suppliers.

Supplier selection with multi-criteria group decision making based on interval-valued intuitionistic fuzzy sets (case study on a project-based company)
Supplier selection can be considered as a complicated multi criteria decision-making problem.In this paper the problem of supplier selection is studied in the presence of conflicting evaluations and insufficient information about the criteria and different attitudes of decision makers towards the risk. Most of fuzzy approaches used in multi-criteria group decision making (MCGDM) are non-intuiti...
