Abstract: |
In order to test the validity of method which choosing extensible weights by simple dependent function, this paper compared of the method in [1] with grey comprehensive evaluation method, and the results of numerical examples have shown that the assessment results for the same problem using two approaches are consistent although their weights are different, so the two approaches are all validity. In addition, according to the case of too many evaluation factors, the concept of factor subsets based on extension theory is introduced, and extensible multi-degree comprehensive evaluation method is put forward in man-machine-environment system. The results of numerical examples have shown that fuzzy comprehensive evaluation, analytic hierarchy process, extensible comprehensive evaluation and grey comprehensive evaluation are all available methods.
