The Subject

Trust management is now one of the interesting research topics in the field of web security. Firstly, several existing trust models are analyzed. Aiming at flaws of these models, the subject trust model based on fuzzy comprehensive evaluation is proposed, thus solving the evaluation problem of subjects trust degree in trust model. An effective evaluation strategy for trust degree vector of subject trust model is given. Finally, a concrete example is provided and has proved the rationality and feasibility of the model.

Instance Analysis

To solve evaluation problem of the structure design of the supporting plate of the steaming Bucket, a evaluation method based on fuzzy comprehensive evaluation was presented for the Supporting Plate. Membership functions for the quantitative and qualitative indicators were built by using the fuzzy statistical test method and fuzzy distribution. On the basis, the evaluation model was built based on fuzzy comprehensive evaluation, each layer of which was evaluated respectively, and suggests the evaluation results of structure analysis of the supporting plate. The instance analysis shows that the method is reasonable and effective.

To increase the protection level of copyright in cloud computing environment, aiming at the problems that the indicators in the copyright protection evaluation system are difficult to accurately define and cannot be quantified, a comprehensive evaluation model of copyright protection based on the combination of analytic hierarchy process and fuzzy comprehensive evaluation is proposed. First, using the analytic hierarchy process (AHP), the copyright protection evaluation system is constructed and the weight of each evaluation index is determined through the judgment matrix. Then the quantitative evaluation result is fuzzy operated through index weight and evaluated data. Finally, the simulation evaluation results on specific example show that this model is reasonable and effective, and it can provide the evaluation basis and practical reference for copyright protection evaluation in cloud computing environment.

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.
