| Abstract: | The concepts of Fuzzy relation and Fuzzy transformation in the Fuzzy theory is applied in gathering and analysing the survey information of the experts group questionnaires for the weightiness of the electronic resources measuring indicators in this paper.Using the method of Center of Gravity Defuzzification to figure out the fuzzy weights and utilizing the reasonable evaluation information from the experts group will improve the reliability of the final evaluation.Finally,we compared the fuzzy weights with the AHP weights and BP NN arithmetic outcome,and come to a conclusion that the application study is validity. |
