Model for Selecting Prefabricated Component Supplier Based on IFAHP-entropy Weight Method and GRAP-VIKOR
In order to select a high-quality prefabricated component supplier,a reasonable and comprehensive prefabricated component supplier evaluation index system is established from the construction unit;the improved fuzzy hierarchical analysis method(IFAHP)and entropy weighting method are used to assign weights to the evaluation indexes,and the weights obtained from the two methods are integrated with the ideal point method;and the GRAP-VIKOR model is utilized to make evaluations of the PC component supplier alternatives.The results show that the model is applicable to PC component supplier selection.
