A Combined Method for Determining the Weights of Interval Grey Numbers in Multi-attribute Decision Making Problems

摘要

This paper discusses the analysis method of grey multiple-attribute decision-making problem. Due to the diversity of the methods to determining the weights in multi-attribute decision making with grey interval numbers, it is desired to comprehensively utilize the advantages of these methods, and a combination method for determining weights is hereby presented. The method has four kinds of attribute value. In view of the characteristic that the attribute value is grey interval number in this method, combined weight is determined by constructing an optimal model based on maximizing deviations principle. This method reasonably solves the problem of determining attribute weights and develops a new clue to the analysis method of the grey multiple attribute decision making. Finally, an example is illustrated to show the effectiveness of the presented combined method.
