Fuzzy distance and proximity method for determining matrix consistency correction

proximity;  judgment matrix;  Consistency

The concepts of distance and proximity in fuzzy theory are used to measure the closeness of the column vectors of the judgment matrix and the sorting weight vectors, starting from the vector with the worst degree of proximity, find out the elements that have the greatest impact on the consistency of the judgment matrix, and use some properties of the consistency inverse matrix to modify it and its symmetric elements. A corresponding computer program has been written to improve the consistency of judgment to make the improvement more convenient. Case studies show that this method can effectively improve the consistency of the judgment matrix and is simple and easy.
