step SB 2: determining a comment set; in the standardized evaluation of power engineering quality management, a comment set is set as V ═ AAAAA, AAAA, AAA, AA, A };
step SB 3: performing single factor evaluation, and establishing a fuzzy evaluation matrix; judging from one factor separately to determine the membership degree of the judgment object to the selected element, namely single factor judgment, and determining the membership degree of each factor to each evaluation level through the single factor judgment;
step SB 4: and (5) performing primary fuzzy comprehensive evaluation.
6. The power engineering quality management standardized comprehensive fuzzy evaluation model as claimed in claim 1, wherein the comprehensive evaluation result in the step S7 is defined as follows:
step SC 1: the comprehensive evaluation score is more than or equal to 95, the evaluation score is divided into AAAAA, which means that all aspects of quality management standardization are in excellent leading level;
step SC 2: the comprehensive evaluation score of more than or equal to 90 and less than 95 is AAAA, which means that the aspects of quality management standardization reach advanced levels and all have advanced experience;
step SC 3: the comprehensive evaluation score of 80-90 is AAA, which means that all aspects of quality management standardization are in a higher level, but individual problems exist;
step SC 4: the comprehensive evaluation score of 70-80 is AA, which means that all aspects of quality management standardization reach average level, but a few problems exist;
step SC 5: a is the comprehensive evaluation score of more than or equal to 60 and less than 70, which means that all aspects of quality management standardization are in a common level and basically meet the requirements, but the problems are more; in addition, the composite assessment score is lower than 60 points and no rating is given; when each first-level index is lower than 60 points, the grade is adjusted down by one grade, and no grade is given at least; every time a quality accident or complaint event occurs, which together cause severe social negative effects, and there is a significant negligence in quality management work at the electrical engineering project level, no rating is given.
