Comprehensive Evaluation Method

This paper constructs a formula for measuring the tourists perceived value index of forest experience base recreation on five dimensions: Scenic resource attachment, Forest cultural experience, Environmental quality perception, “Two mountains” concept identity, and leisure time activities. Taking Bamboo Expo Park Forest Experience Base in Tianhuangping Town, Anji County, Huzhou City of Zhejiang Province as an example, a comprehensive evaluation method based on fuzzy entropy weight is used to evaluate and analyze the tourist perception value index of the Bamboo Expo Park Forest Experience Base recreation. Research shows that the tourist’s perceived value index of the base for recreation is 90.92, revealing that the tourist’s perceived value is roughly 10% off the Bamboo Expo Park Forest Experience Base ticket price.

Water Environmental Quality

There are lots of methods of evaluating the environmental quality of groundwater. Based on a comprehensive analysis of those common methods, this paper puts forward a method named fuzzy comprehensive evaluation method on water environmental quality based on entropy weight with consideration of toxicology of evaluation factors. Developed from the entropy-based fuzzy comprehensive evaluation method, this method takes into account the influences caused by the toxicology weight and over standard weight of evaluation factors on the calculation of entropy weight. Through some water samples, the evaluation result of this method is more reasonable, objective and comprehensive than the one which is concluded from the entropy-based fuzzy comprehensive evaluation method.

Comprehensive Evaluation Method

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.

For getting an objective assessment of product quality efficiently, the comprehensive evaluation method of generalized product quality was used to evaluate products. At the same time, the index weights were determined by entropy weight method. Taking air screener as example in this paper, we used the comprehensive evaluation method of generalized product quality which was based on entropy weight method to evaluate many types of air screeners and used the software which was made with VB to calculate the data, it made the evaluation process more objective and reliable. The result which was got with this method provided the scientific basis for users to choose the products and for companies to improve the product's quality.

For the accuracy of the inrush risk assessment of the problem, put forward in the mine inrush risk assessment using the entropy weight fuzzy comprehensive evaluation method to determine the index weight, through the membership function in fuzzy comprehensive evaluation to quantify the qualitative description of these factors, evaluated the henan jiaozuo mine inrush risk. The results show that the mine water inrush risk grade is "great", the actual mine water inrush accidents have occurred, prediction results conform to the actual situation, and safety evaluation value based on the principle of maximum membership degree is more than analytic hierarchy - fuzzy comprehensive evaluation to get , 0.0696. Thus, the method in the mine inrush prediction can objectively and accurately reflect the actual situation of mine inrush.
