An Interval Multi-attribute Decision Making Method Based on Incomplete Information

In order to solve the multi-attribute decision making (MAMD) problems of which indexes and their weights are incomplete, the interval number is used in this paper. Based on the possibility-degree matrix, an interval MAMD method is proposed to solve the MAMD problems under incomplete information, by convergence and sequence. The given instance shows that it is feasible for the interval MAMD method to solve MAMD problems under incomplete information.
