Method of grey related analysis to multiple attribute decision making problem with interval numbers

Abstract

Firstly, decision making matrix of interval numbers multiple attribute decision making problem by norm of interval number vector is standardized. Then, it transformed an interval number multiple attribute decision making problem into multiple attribute decision making problem with intervalalued indeses by the multiplication operation of interval number. On the basis of this, the method of grey related analysis to interval number multiple attribute decision making problem is given, and a practical problem is analyzed by this method. This method is simple, practical and demand less information. It analysed a concrete problem with this method.
