Approach to incidence decision making model of multi-attribute interval number on supplier selection

The selection of suppliers is a problem of complicated multi-attribute decision. According to the features of suppliers selecting and grey incidence theory, this paper researches on the multi-attribute strategy with interval number, constructs the evaluation indicators system of suppliers´ selection, puts forward the computing method of interval number correlation, builds up a internal number correlation decision-making model and makes the multi-attribute decision of suppliers selection realized. Moreover, the paper further employs practical cases to validate the effectiveness and practicability of the model.
