Safety And Reliability

All the factors causing distribution system faults are analyzed for improving safety and reliability of power system. Comprehensive and scientific evaluation for distribution system faults are made by fuzzy comprehensive evaluation method and the ordering is done by their severities. This method is able to monitor the distribution system safety and reliability and give reference for distribution system condition-based maintenance, thus improve the ability of distribution system safe operation.

Subjective Weight

The plan for power supply and distribution system in the Chemical Industry Park is complex. The evaluation method must be easy and truly show the site conditions in order to maintain the proper function of the system. Thus the fuzzy comprehensive evaluation method was chosen and applied in this paper. As for the weight calculation, Analytic hierarchy process (AHP) was used to compute the subjective weight; on the purpose of avoiding strong effect of subjective factors, the standard deviation for each index was calculated, and then the subjective weight was integrated to build the subjective and objective comprehensive weight model. Lastly fuzzy comprehensive evaluation method was applied into the model for assessing the power supply and distribution system in the Chemical Industry Park.

Safety And Reliability

This paper first introduces fuzzy comprehensive evaluation method to mine machinery. We evaluate the mine elevator braking system's reliability comprehensively from the perspective of the system. Application of the engineering calculation method can prove the reliability of the whole braking system systemically and completely. The precise data of real-time reliability could supply scientific and reliable information directly to hoist staff. The introduction of the method makes up the blank of analysis for elevator braking system safety and reliability, and provides a new thinking for performance evaluation of mining machinery.

An indicator system is established for the suitability of projects linked to the increase/decrease in urban and rural construction land based on the field surveys for the old areas to be dismantled in three administrative villages such as Niulandian Village, Tianjiagou Village and Nanchongsi Village of Tianchi Town in Lezhi County of Sichuan Province, and the fuzzy comprehensive evaluation method is used to evaluate indicators. The analysis of evaluation results provides reference for the efficient implementation of projects linked to the increase/decrease in urban and rural construction land.
