In order to study the influence of distributed power access on the security state of distribution network, a comprehensive evaluation method for the security state of distribution network including distributed power access was proposed.Based on the output model and load model of photovoltaic power supply, the security situation assessment index system of distributed power supply access distribution network is established. Then combined with fuzzy analytic hierarchy process and entropy weight method, the composite weight of each index is obtained, and the combined weight is optimized based on chi-square distance. Finally, the evaluation method based on ER algorithm (Evidential Reasoning) is proposed. Simulation results verify the effectiveness and accuracy of the proposed method.

This paper analyzes the development evolution of urban ecosystem health of old industrial relocated area on the base of the urban ecosystem health theories and methods. Taking Tie Xi District in Shenyang city as an example, the paper discusses the assessment index system of the urban ecosystem health of old industrial relocated area. Then the paper employs Analytic Hierarchy Process to determine the index weights and takes use of Fuzzy Comprehensive Evaluation Method to study the case.

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.

In order to evaluate coaches, this paper established the model of comprehensive evaluation based on analytic hierarchy process (AHP). Firstly, I establish the hierarchical structure of the system; Secondly, for researching the influence of time line horizon in analysis, I divided coaches into several groups by their career time and calculated the weights of indicators of each group using entropy weight method; Finally, calculate the weight between the criteria layer and objective layer. Female coach data is difficult to find, so I select 100 college basketball male coach data. Put the data into model and get a score. The score showed the final result which can give us a sort of reasonable coach list. This model can reduce the influence of different time periods for evaluation of the coach.

In this paper, the Market-oriented Operations Strategy of CCHP are analysed, from the perspective of construction mode, operating mode and charging mode. On this basis, a three-dimensional indexes system is established, and combining the entropy weight method with Analytic Hierarchy Process as a comprehensive evaluation method to evaluate the different market-oriented strategies of CCHP. Finally, the empirical analysis of the commercial building in southwest China shows that the market-oriented strategy of CCHP can bring more benefits to market participants when it has high applicability and great practical value.
