The multi-attribute weighing decision model of grey target based on savage decision criteria

This paper studies on the multi-attribute weighing decision model of grey target based on theories of decision-making analysis. Concerning of Savage decision criteria under the circumstance of uncertain decision, grey interval number series have been put forward to extend definition of real number series as well as a ranking method has been given according to the distance from Grey target. In this case, a decision model of multi-indicator and weighing grey target is developed based on grey target decision theory. Such method provides a new approach of multi-indicator interval grey number decision. Finally, the effectiveness of the method has been verified by a real example.
