A New Algorithm for Incomplete Matrixes'''' Compatibility Improvement and Group Ranking in Group Decision Making
群组决策中残缺判断矩阵的相容性修正及排序新算法

Compatibility Improvement is a key step in AHP applied in group decision making. But many literatures only discussed how to verify the Compatibility.Although some papers provided methods to improve compatibility,they did not take enough factors into account,such as incomplete matrix,different weights between experts and the reliability of matrixes after amending.Owing to the shortcoming of existing methods,we put forward a new algorithm based on possibility-satisfiability degree.By this method,we could resolve the problems mentioned above very well. The final example proved the flow and efficient of the new method.
