The defects of present fuzzy comprehensive evaluation model based on interval value are pointed out. To improve these defects, a new calculation method of fuzzy membership degree is provided and a fuzzy comprehensive evaluation model based on interval number distance is built. This model is applied to Lake Dongchang. And it can be indicated that the proposed model is reasonable and practical.

We generally use methods of statistical forecasting and antithesis in projects post evaluation, but they can only be used as a qualitative evaluation but as a quantitative evaluation. Based on the fuzzy mathematics, this text presents a better quantitative mathematical analysis-fuzzy comprehensive evaluation method. And then, it established a model of comprehensive fuzzy assessment of projects post evaluation. At last, it illustrate that the model of comprehensive fuzzy assessment can evaluate projects post evaluation accurately and quantitatively.

On the basis of the basic theory of post evaluation of power transmission and transformation project in this paper, it selects the multi-level fuzzy comprehensive evaluation method to evaluate the project. Take the Qian Fangzi power transmission and transformation project as an example;It has carried on the empirical research. From the process of the project implementation, economic benefits, the influence of the project, sustainability evaluation and so on, it has achieved good results and proved the effectiveness of the proposed evaluation model.

In order to ensure quality of highway alignment design, and reasonably evaluate the design proposal, the main factors which affect the highway alignment design, including horizontal alignment design, vertical section design and combination of horizontal and vertical design, are analyzed. Based on these key factors, a system of evaluation based on game theory is constructed and the evaluation index is normalized from both qualitative and quantitative view. So an evaluation model of highway alignment design is established. Under the situation of highway alignment designs, the model and fuzzy comprehensive evaluation method are applied to determine the most suitable alignment design for that city. The best choice, design 3rd, is identical, but the sort of design 2nd and design 4th is not consistent with each other for the reason of large deviation of weight of the fuzzy comprehensive evaluation method. Because the evaluation model based on game theory can better determine the optimal weight, the evaluation is more reliable and it meets the practice. The results show that the model is effective and reliable.
