Supplier Selection Decision-Making Model Based on Entropy and Its Application in the Large Aircraft Project

Aiming at the deficiency existing in the supplier selection decision method, we proposed supplier selection model, which is based on the risk factors of mixed information. By using the method of standardization, the interval numbers are converted to intuitionistic fuzzy number, considering the risk factors influence on supplier selection, establish intuitionistic fuzzy numbers and linguistic variables, making the hybrid multiple attribute decision in the framework of unified in the same decision; Then using the weights of the extension of entropy model, by intuitionistic fuzzy set of fuzzy entropy calculation of expert judgment information degree, weights of each expert to sort through relative entropy method to get the ranking results of each expert, according to the weighted arithmetic operators gather information, each expert judgments have alternative suppliers. Applying the model into solving large aircraft project vendor selection of practical problems, which is indicated that the model can effectively avoid large aircraft project risk in the choice of suppliers.
