Each influence factor had the obvious fuzzy characteristic in view of the mine ventilation system, the utilization fuzzy mathematics method has established one kind of new ventilation system rationality fuzzy mathematics judgment model, carried on the synthesis judgment to the ventilation system rationality, this judgment method could give the quota description direct-viewing to the system rationality. Finally, take some mining bureau's four ore as the example, has confirmed the model rationality. This method may operational strong, the effect be better, may in the general mine ventilation system appraisal the widespread application.

Comprehensive Evaluation Method

<p style="margin: 1em 0px;"><span lang="EN-GB"><span style="font-family: Times New Roman; font-size: medium;">In order to reduce the energy consumption and enhance the robustness of wireless sensor network (WSN), this paper proposes a hierarchical clustering routing algorithm based on fuzzy mathematics (HCRAFM). To make a comprehensive analysis of WSN, it is also necessary to detect the robustness of the network. Facing the multiple random variables, the traditional robustness detection models assume that all nodes have the same weight, making it impossible to quantify the analysis indices or obtain accurate results. Thus, the fuzzy mathematics theory was introduced to the WSN robustness detection, forming a fuzzy comprehensive evaluation method. The simulation results show that the HCRAFM strikes a load balance between WSN nodes, extends the life cycle of each node, and prolongs the service life of the network. In addition, the proposed algorithm is proved to have sound robustness and strong applicability.</span></span></p>

Weihe is the largest river in Shaanxi province. The comprehensive evaluation of the monitoring datas in 2012 in Weihe Tongguan drawbridge section was presented in this paper by using the FCE method. The results showed that the water quality pollution levels in this section are Class V, I, IV and V respectively in the four quarters which are spring, summer, autumn and winter, the main pollutant is NH3-N. Compared with the traditional method of single factor assessment, this method can reflect the water quality more comprehensively and reasonably.

The fuzzy comprehensive evaluation which is one of the important embranchment of fuzzy mathematics is often used in the field of science management and decision, but less used in the machining process. Based on the fuzzy mathematical theory, we put forward the establishing process of fuzzy comprehensive evaluation model, and then set up the three-grade fuzzy comprehensive evaluation model of cutting sequence. Three cutting sequences of multi-feature bearing chock component have been evaluated, the evaluation results have verified the rationality and trueness of the model. The application and dissemination of the fuzzy comprehensive evaluation will have active significance in the machining process.
