A Novel Method Combining Grey Target Decision Model with Close Value for Material Selection Problem

Abstract:

Aiming at the material selection problem, a new selection method is proposed combining the multi-target grey target decision model with close value method. The new method can reflect the alternative is close to the bull's-eye and away from the close value minus the bull 's-eye, which overcomes the traditional grey target decision model of sorting scheme only consider is distance to target's influence on the decisions without considering the negative distance to target. And the variation coefficient method is used to objectively determine the index weight, avoid the arbitrariness of previous subjective weight determination. Finally, the practical example of a material selection problem is given to illustrate the practicability and effectiveness of the decision making process.
