According to constraint elements more and more appearing in the comprehensive forms, and at present it only considers that single constraint element of city underground space development and utilization has been unable to reflect the actual situation. On the basis of the main characteristics of city underground space development and utilization, this paper aims to analyze various factors which may cause the consequence and the frequency of appearance, and to construct evaluation index system of city underground space development and utilization which is composed of 5 one-level indexes, 20 two-level indexes of evaluation index system of multiple constraint factors of city underground space development and utilization, and to use the analytic hierarchy process and fuzzy comprehensive evaluation method to analyze and evaluate the influence on city underground space development and utilization. Analysis of the example application shows that, it only considers single constraint element of city underground space development and utilization is not comprehensive, and not science, and it needs to consider the correlation between various constraint elements.

Implementation of reverse logistics is the foundation of developing circular economy and realizing sustainable development. According to the characters of green logistics, multi level evaluation index system of green degree of reverse logistics system is built in this paper, the weight of each index is determined by using the analytic hierarchy process, the system green degree is evaluated by applying the fuzzy comprehensive evaluation method and the result is analyzed. The result shows that the method is simple, accurate and has a good application.

Based on the gearbox as the research object, we discussed the problem: how to confirm every part’s weight when assess gearbox’s state by fuzzy comprehensive evaluation method. Contraposing the main problem of the weight-fixed Analytic Hierarchy Process (AHP) that ignoring every part’s fault degree in the process of evaluation, a variable weight method is proposed base on the rate of fault degree contribution. And to a state known gearbox, the weight of each part in the whole gearbox assessment is confirmed by the AHP and the variable weight method respectively. The comparison of the two assessment results shows that the result get by the variable weight method is more close to the gearbox’s real state, so this method is more accurate. What’s more this method is very simple, and can be used in real project.

To utilize the objective information of index data and consider the important role of subjective judgment in the evaluation of distribution automation equipment testing results, a comprehensive evaluation method based on AHP (Analytic Hierarchy Process) and CRITIC (CRiteria Importance Through Intercriteria Correlation) method is proposed. Firstly, an evaluation index system of distribution automation equipment testing results considering seven big indicators and thirty-six small indicators is established. Secondly, AHP and CRITIC method are adopted to solve a practical evaluation problem of distribution automation equipment testing results. The subjective weights of each evaluation index are calculated by AHP, the objective weights of each evaluation index are calculated by the CRITIC method. Then, to achieve the sorting of distribution automation equipment testing results accurately, the comprehensive weights are obtained by combining the two weights. Finally, the analysis and comparison of case studies show that the proposed evaluation index system can accurately reflect the performance of distribution automation equipment and the comprehensive evaluation method of distribution automation equipment testing results which comprehensively considers the subjective comprehensive evaluation results.

This paper presents an optimization method for gear processes; through this method, the most worth optimized processes can be obtained and optimized, thus improving the reliability and supportability of gear products. Firstly, the POPN (Process Optimization Priority Number) analysis method considering the current process level and the process improvement cost is proposed with reference to the RPN (Risk Priority Number) analysis method to obtain the most worth optimized processes. Due to the fact that the unreasonable weight distribution of importance (I), changing difficulty (C), rationality (R), and detective difficulty (D) still exists in the POPN analysis, then combining the POPN analysis method and the AHP (Analytic Hierarchy Process)-fuzzy comprehensive evaluation method to evaluate and rank the FPOPN (fuzzy POPN) level of each process, the higher the FPOPN level is, the more the process should be optimized. Finally, according to the evaluation results, some processes with high FPOPN level are optimized and the optimal parameters’ combination of these processes is obtained through the tests based on the Taguchi method. A detailed optimization example is also given from the beginning to end in accordance with the above methods, and compared with the original process gears, the optimized gears have a big increase in gear performance through the above optimization method.
