Performance status evaluation is essential for the safe running of electric vehicle (EV) charging infrastructure. With the development of the EV industry, the EV charging infrastructure industry has advanced considerably. Safe and reliable operation of the charging infrastructure is important for the development of EVs. As such, we propose a comprehensive evaluation method to assess the performance condition of an EV charging infrastructure. First, based on the analysis of the existing EV charging principles, we established an evaluation index system for EV charging infrastructure. Second, the subjective weight, objective weight, and comprehensive weight of the index system were determined through analytic hierarchy processes (AHP) and the entropy weight method. Then, we used fuzzy comprehensive evaluation to appraise the performance of the charging infrastructure through expert investigation. Finally, based on the actual data from an EV charger, the performance conditions of the EV charging infrastructure were evaluated to demonstrate the feasibility of the method and the reliability of the index system.

Patent Strategy

The implemented performance of enterprise’s patent strategy is an important component to measure its comprehensive benefits. It is of strategic significance for an enterprise to evaluate objectively its implemented performance of patent strategy. From the perspective of sustainable development, according to the 4 aspects of creation, application, protection and management of patent, the essay constitutes preliminarily a comprehensive evaluation index system of the implemented performance of enterprise’s patent strategy which is composed of a set of 21 indexes on the basis of an amount of domestic and foreign literature survey, case study and expert consultation, and analyzes the evaluation model and method of implemented performance of enterprise’s patent strategy with the fuzzy comprehensive evaluation and through a real case. The essay thinks the constitution of evaluation index system should obey a series of basic principles of objectivity, systematization, science and conciseness and the evaluation in essence is multi-object, multi-factor and multi-layer. Therefore, it is effective and feasible to select the Fuzzy Comprehensive Evaluation method.

Slope Structure

Highway collapse hazard is the combined result of many factors. Based on the formation mechanism of the road collapse hazard and main the factors, they are selected from three aspects of risk assessments master factor: the regional geological structure, slope characteristics, and regional environmental characteristics, also ultimately select the spacing of the joints, slope lithology, slope structure, slope height, slope gradient, rainfall (rainfall in 24 hours to ≥ 25mm of days), the vegetation coverage degree and earthquake strong eight main control factors, above all these factors, they established a road collapse hazard evaluation index system. Based on the fuzzy comprehensive evaluation method, it establishes a road collapse hazard evaluation model. Analytic Hierarchy Process is used to determine the evaluation index system of layers in index weight values. Risk index is based on the evaluation criteria. Finally, an empirical study of two highway projects instances.

On the basis of current situations of urban underground transportation junctions and combining with on-site investigation of Beijing Xizhimen transportation junction station, this paper puts forward the disaster-prevention index system of urban underground transportation junctions. Specific analysis is on the disaster index in four aspects: informational sign, fire-fighting equipment, evacuation capability and refuge. 17 indexes are extracted reflecting the disaster evacuation performance, the weights of each disaster-prevention index are defined by Analytic Hierarchy Process (AHP), and fuzzy comprehensive evaluation method is adopted to conduct comprehensive evaluation of safety performance. The established disaster-prevention index system has practical value and significance to improve the disaster-prevention capability of urban underground transportation junctions.
