For getting an objective assessment of product quality efficiently, the comprehensive evaluation method of generalized product quality was used to evaluate products. At the same time, the index weights were determined by entropy weight method. Taking air screener as example in this paper, we used the comprehensive evaluation method of generalized product quality which was based on entropy weight method to evaluate many types of air screeners and used the software which was made with VB to calculate the data, it made the evaluation process more objective and reliable. The result which was got with this method provided the scientific basis for users to choose the products and for companies to improve the product's quality.

According to the subjectivity, randomness and fatigue of the satisfaction selection of online teaching evaluation indicators for the students, the level of teachers teaching can not truly measure by the evaluation results. This paper introduces the fuzzy comprehensive evaluation method to deal with the evaluation data, and Practice has proved that this method produced results more equitable to reflect on teaching level. Which help teachers to promptly improve and improve teaching, the variable quality of teaching time control for process control, change the static management for dynamic management.

Environment Sustainability

In order to evaluate the atmospheric environment sustainability in the provinces of Northeast China, this paper has constructed a comprehensive evaluation model based on the rough set and entropy weight methods. This paper first constructs a Pressure-State-Response (PSR) model with a pressure layer, state layer and response layer, as well as an atmospheric environment evaluation system consisting of 17 indicators. Then, this paper obtains the weight of different indicators by using the rough set method and conducts equal-width discrete analysis and clustering analysis by using SPSS software. This paper has found that different discrete methods will end up with different reduction sets and multiple indicators sharing the same weight. Therefore, this paper has further introduced the entropy weight method based on the weight solution determined by rough sets and solved the attribute reduction sets of different layers by using the Rosetta software. Finally, this paper has further proved the rationality of this evaluation model for atmospheric environment sustainability by comparing the results with those of the entropy weight method alone and those of the rough set method alone. The results show that the sustainability level of the atmospheric environment in Northeast China provinces has first improved, and then worsened, with the atmospheric environment sustainability level reaching the highest level of 0.9275 in 2014, while dropping to the lowest level of 0.6027 in 2017. Therefore, future efforts should focus on reducing the pressure layer and expanding the response layer. Based on analysis of the above evaluation results, this paper has further offered recommendations and solutions for the improvement of atmospheric environment sustainability in the three provinces of Northeast China.

Hierarchy Process

In order to evaluate coaches, this paper established the model of comprehensive evaluation based on analytic hierarchy process (AHP). Firstly, I establish the hierarchical structure of the system; Secondly, for researching the influence of time line horizon in analysis, I divided coaches into several groups by their career time and calculated the weights of indicators of each group using entropy weight method; Finally, calculate the weight between the criteria layer and objective layer. Female coach data is difficult to find, so I select 100 college basketball male coach data. Put the data into model and get a score. The score showed the final result which can give us a sort of reasonable coach list. This model can reduce the influence of different time periods for evaluation of the coach.

This paper first introduces research about green supply chain management, and points out the differences between green supply chain management and traditional supply chain management according to the characteristics of green supply chain. Then, the paper analyses the sources of risk in green supply chain management fundamentally and constructs a risk evaluation system owing to the classification of sources. Finally paper makes a quantitative analysis to the risk of green supply chain with the fuzzy comprehensive evaluation method.

The evaluation object is defined more reasonable. This paper establishes the student evaluation system by scientific questionnaire firstly, then determines the index weights by using AHP, thirdly quantifies the qualitative indexes according to the fuzzy comprehensive evaluation method. Finally we get each student’s score of the student evaluation system. Aiming at freshmen and sophomore , the student evaluation system can objectively reflect the students' comprehensive quality and have a guiding significance for improving the students' comprehensive quality.

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.
