A Multi-attribute Decision Analysis Method Based on Rough Sets Dealing with Uncertain Information.

Information in emergency situation are always uncertain, which presents as incomplete or inaccurate. As a consequence, it is difficult to make decision correctly and rapidly enough in an emergency. A multi-attribute decision making method is proposed based on the concept of extended dominance relation and variable precision rough sets in this paper. Firstly, the definitions of extended dominance relation and variable precision rough sets are introduced in detail. Secondly, two types of extended dominance rules are obtained from the pairwise comparison table. Thirdly, a scoring function is defined and sorted to score all the objects. Finally, a case about the emergency decision making after an earthquake is discussed to demonstrate the feasibility and efficiency of the method. © 2011 IEEE.
