Based on coal seam geological condition and mining technological characteristic in Jisan Mine, coal seamgeological condition is quantitative evaluated by using fuzzy evaluation with the view of coal mining and coalfaceproduction. The structure and index system of evaluation factor, the membership functions and weights of evaluationfactor, evaluation model and reliability in the coal seam geological conditions are expounded in detail. Eighty-twocoalfaces which will be exploited is classified. All of these have provided a theoretical foundation for the selection ofcoal mining technology and for sustainable development of the coal mine.

A quantitative and comprehensive method of product life cycle assessment(LCA) with fuzzy theory is developed, which will help designers to select the optimum design scheme for product life cycle design(LCD). Based on the theory of multiple attribute decision making, an algorithm of comprehensive and comparative evaluation for product environmental adaptability is presented. A program is built and used in an example of design improvement. The result shows that the proposed method and algorithm are practical and effective to the development of green products.

The paper analyzes the factors influencing machine tool selection. By using fuzzy mathematics theory, we establish a theorietical model for optimal machine tool selection considering geometric features, clamping size, machining range, machining precision and surface roughness. By means of fuzzy comprehensive evaluation method, the membership degree of machine tool selection and the largest comprehensive evaluation index are determined. Then the reasonably automatic selection of machine tool is realized in the generative computer aided process planning （CAPP） system. Finally, the finite element model based on ABAQUS is established and the cutting process of machine tool is simulated. According to the theoretical and empirical cutting parameters and the curve of surface residual stress, the optimal cutting parameters can be determined.

Green supply chain is one of the trends of industry development. And performance measurement is the key to implementing the supply chain. So it is necessary to evaluate the environmental performance of supply chain .According to the connotation of green supply chain and the standards of environmental management, this paper designs green performance measurement systems which is composed of four main factors such as waste emissions and exposure hazard, resource utilization, product recovery, and environmental reputation. And the authors delve deeply these factors so that it forms a two-level measurement system. Then the effect on the traditional performance measurement of supply chain is studied after taking greening to the supply chain leveL At last the authors apply the method of multi-level fuzzy judgment to the environmental performance measurement system. An example is given to show the judgment process.

An index system for evaluating the demand side management （DSM） on railway temporary power system is established in this thesis, and the part weight and the whole weight of the index system are calculated by the analytic hierarchy process （AHP）. The basic theory of fuzzy evaluation is introduced, and the feasibility of applying it to DSM on railway temporary power system is analyzed. Through the establishment of index system, evaluation and comparison to DSM projects can be carried out horizontal and vertical. Then identify gaps and weaknesses, analyze the causes guide the consciousness of energy conservation and environmental protection, supervised of electricity in an orderly manner, establish DSM long-term management mechanism.

An evaluation model was developed to evaluate the ability of agricultural innovation in science and technology using fuzzy mathematics method. The core component of the model included a fuzzy relation matrix of the evaluation indexes based on membership function. The model was applied to Lianyungang, China as a case study. The result showed that the comprehensive agricultural innovation ability in science and technology in Lianyunguang, China is in the middle level, which is basically consistent with the fact. This study demonstrated that the comprehensive fuzzy evaluation model is highly operable and feasible.
