Safety Accident

For many risk events in civil engineering construction have the property of “the connotation is explicit, the extension is vague”, the influencing factors of civil engineering construction safety accident are measured with the membership degree in fuzzy mathematics. The weight of indexes of various influencing factors is calculated with the method of analytic hierarchy process, thus a fuzzy comprehensive evaluation model for civil engineering safety accident is given, which is a new qualitative and quantitative solution method and makes it become possible for the early warning of civil engineering construction safety accident. In the end, it is demonstrated with an actual example for the availability of the model in the early warning.

Fuzzy Hierarchy

Consequences of dam-break are affected by many factors, which are of a certain degree of ambiguity. Influencing factors of dam-break consequences are summarized in this paper. At first, weights of influencing factors are determined by means of Analytic Hierarchy Process （AHP）, thereafter, the fuzzy hierarchy synthesis evaluation model for dam failure is developed. Finally, Qing Linjing reservoir located in Shenzhen of China is taken as a case. The fuzzy comprehensive evaluation for the risk analysis of dam-break and the risk grades of dam-break consequences are obtained. The results indicate that it is reasonable and valuable to evaluate the risk of dam-break by using fuzzy comprehensive evaluation.

Teaching Goals

Education evaluation promotes the scientific management of physical education (PE), and facilitates the realization of teaching goals of PE lessons. Through fuzzy comprehensive evaluation (FCE), this paper explores the influencing factors of teaching evaluation system for PE. A new evaluation index system (EIS) of PE was constructed through expert evaluation, the weight values of each index were determined through analytic hierarchy process (AHP), and an FCE model was established for PE. Taking a college PE teacher as the research object, the application effect of the proposed FCE model was empirically investigated. The results demonstrate the practicality and feasibility of the proposed model. The FCE model can qualify PE evaluation results comprehensively, and support the overall evaluation of a single factor. The modeling results reflect the actual teaching effect from multiple layers, and help to rationalize PE in the light of specific factors. The research provides important theoretical and realistic evidence to the promotion of PE evaluation.

Cellular Concrete

The durability of lightweight cellular concrete (LCC) and the corresponding assessment method are studied in this paper to improve the utilization of LCC in subgrade construction engineering. The durability assessment method is established by combining the analytic hierarchy process (AHP) with fuzzy comprehensive evaluation (FCE). The main assessment processes are as follows. Firstly, based on the physical and mechanical properties of LCC, the influencing factors are selected in terms of preliminary design, construction technology, and operation and management after completion of construction. The grading standard of influencing factors is established as well. Secondly, a multilevel assessment model with targets level, criteria level, and indexes level is established. AHP determines the effective weight of the lower level relative to the upper level. The consistency check of the judgment matrix is conducted to prove the rationality of the distribution of influencing factors’ effect weight. Thirdly, the membership function which is suitable for each influencing factor is built to calculate the membership degree. Besides, the practicality and reliability of AHP combined with FCE are demonstrated through a practical engineering case, which is the third section of a highway in Guangdong Province, China.

Tunnel Design

At present, the tunnel design specifications in China do not provide a clear and systematic intelligent evaluation system of tunnel frost damage in cold regions. Based on the research results of 122 seasonal frozen soil tunnels in high-latitude areas of China, four key influencing factors of geohydrology, temperature, surrounding rock, and engineering measures were determined, the intelligent fuzzy comprehensive evaluation model was established, the weights of all factors were considered, and the intelligent evaluation technology system of tunnel frost damage in cold areas had been put forward. Meanwhile, the rationality of the intelligent model was verified by a specific engineering case. The research suggests that the intelligent evaluation model of tunnel frost damage proposed in this paper can accurately describe the relationship of influencing factors of tunnel frost damage in cold areas, the weight of each influencing factor is calculated by using analytic hierarchy process, and the main risk sources of tunnel frost damage in cold areas are found out. The intelligent evaluation model is an efficient and practical method for Intelligent prediction of frost damage. By using the subordinate function method, the improvement from qualitative analysis to quantitative index calculation is realized. The blindness of engineering analogy construction is avoided, and the scientificity and accuracy of renovation measures for frost damage have been improved. At the same time, the research results provide a theoretical basis for the improvement of the intelligent evaluation system of tunnel frost damage in cold regions.

The Status

An equipment status management and maintenance platform of an intelligent substation monitoring and control system is built in the Tai-Tam substation of the Taipower company. The real-time operating status of the equipment, such as the server, supervisory control and data acquisition (SCADA) human–machine interface (HMI) software, switches, intelligent electronic devices (IEDs), merging units (MUs), as well as the entire SCADA system, are evaluated comprehensively. First, the status information of all equipment is collected, and the theory of relative deterioration degree (RDD) and fuzzy theory (FT) are applied to calculate the fuzzy evaluation matrix of the equipment influencing factors. Then, the subjective analytic hierarchy process (AHP) and the objective entropy method for weighting are combined to calculate the comprehensive weights of the equipment influencing factors. Finally, the result of the equipment status evaluation is obtained using the fuzzy comprehensive evaluation (FCE) method and is presented at the equipment status management and maintenance platform. Such equipment status evaluation results can be used by the inspection and maintenance personnel to determine the priority for equipment maintenance and repair. The result of this study may serve as a valuable reference to utility companies when making maintenance plans.

Abstract In China, rural domestic sewage treatment has become an urgent problem to be solved to improve the rural human settlement environment. However, there is no scientific, objective, and systematic evaluation model for selecting rural domestic sewage treatment technology. Therefore, this paper mainly studies on the establishment of the evaluation system model of China's typical rural domestic sewage treatment technology and the application of technology selection. Based on the analytic hierarchy process and the life cycle method, the experts consulted and analyzed the factors affecting the evaluation of China's rural sewage treatment technology. The comprehensive evaluation index system suitable for China's rural sewage treatment technology was established based on the analysis results. Combined with the fuzzy comprehensive evaluation method, five typical rural domestic sewage treatment technologies were applied and analyzed. The results show that the comprehensive evaluation of the biofilm technology is the best at 3.5669, followed by the septic tank treatment technology and land treatment technology, which are 2.8829 and 2.8422, respectively. The case analysis verifies the applicability of the model, which can support the selection of technologies for the rural domestic sewage treatment market in China.
