Establish a nonlinear membership function of slope stability taking the case of six different sliding blocks on a typical slope and do a second class fuzzy comprehensive evaluation on the determinate membership. Comparing the result of stability evaluated with former result determined by extension classified method, it shows that it is basically conforming to evaluate slope stability using membership function which is established according to the changing rules of impact factors of slope such as quality of rock, massiveness of rock mass and dip angle of rock. This method can be referential in a qualified sense for the forecasting and preventing of landslide disasters.

The evaluation of technological process in CAPP based on fuzzy mathematics was explored and researched. Aiming at fuzzy auto-evaluation，factors set, weight set and assessment set were built with the applying membership function and weight of fuzzy mathematics .Then the evaluation matrix of technological process was received through fuzzy matrix calculation. According to the principle of maximum membership degree, the grade of technological process was determined. The optimum technological process was obtained on the comparison among the grades of processes, giving an example of the automatic fuzzy comprehensive evaluation for the disc-like component.

This paper mainly studies the application of intelligent lighting control system in different sports events in large sports competition venues. We take the Xiantao Stadium, a large­scale sports competition venue in Zaozhuang City, Shandong Province as an example, to study its intelligent lighting control system. In this paper, the PID (proportion – integral – derivative) incremental control model and the Karatsuba multiplication model are used, and the intelligent lighting control system is designed and implemented by multi­level fuzzy comprehensive evaluation model. Finally, the paper evaluates the actual effect of the intelligent lighting control system. The research shows that the intelligent lighting control system designed in this paper can accurately control the lighting of different sports in large stadiums. The research in this paper has important practical significance for the planning and design of large­scale sports competition venues.

In this study, a hydrochemical investigation was conducted in Shuangliao city to identify the hydrochemical characteristics and the quality of groundwater using descriptive statistics and correlation matrices. And on that basis, combined with Analytic hierarchy process (AHP), an improved two-level fuzzy comprehensive evaluation method is used to evaluate the groundwater quality. The results indicate that the major cations and anions in groundwater are Ca2+ and HCO3-, respectively. The chemical types are mainly HCO3—Ca type water, some areas are complicated due to the influence of human activities. The evaluation results show that the water quality in the area is mostly III type water, and the groundwater quality in some areas is IV or V water due to the influence of primary geological conditions or human activities. The groundwater quality in the East Liaohe River Valley and Shuangliao urban area is relatively poor, and in the northwest part which is the saline alkali soil area is also relatively poor.
