To establish the evaluation model of the garment fabric, the method of fuzzy system theory was used to value the the mechanical properties of one bias cut garment’s the fabric and improved gray correlation degree analysis was used to calculate the weight of each properties index. The subjective judgment on fabric was quantitatively processed, which further refine the complex optimal selection of fabric problem and provided a new way for the optimization of garment fabrics.

Comprehensive Evaluation Model

According to the characteristics of resource allocation for engineering construction programme, the comprehensive evaluation model of resource allocation rationality for programme is established with the combination of analytic hierarchy process and fuzzy comprehensive evaluation method. The rationality of resource allocation for programme is evaluated objectively based on the assessment of correlation degree between monomer project and the programme and the evaluation of resource allocation rationality for monomer projects. And the evaluation results have been analyzed and sorted through the principle of weighted average.

Large customers direct electricity purchase mode is a new electricity purchase mode introduced in the electricity market reform. It can not only further explore the potential of electricity market, but also introduce the competition mechanism on the electricity sale side, perfect the price system to rationally allocate resources according to the price signal. Combined with chinas electricity market-oriented reforming direction, this paper learns from the abroad electricity direct purchase experience, relates the important and difficult issues in large customers direct electricity purchase and finally figure out the sequence of large users direct electricity purchase. Structurally,based on the analysis of the basic theory, it builds an evaluation indicator system of large customers direct electricity purchase from multiple types of power suppliers and further use entropy method to process consistently and dimensionless. Finally combines gray correlation degree with ideal point method to evaluate the sequence of direct electricity purchase.

To solve the existing fuzziness in the grading of stability evaluation of geocell protected slope and inconsistent between evaluation result by single index and the fact, this paper establishes index system of the stability evaluation of geocell protection of slope and propose a method. First, two-grade Fuzzy Matter-element Model is established based on the index system. Second, factor weights of evaluation index are calculated by AHP. Finally, the grade of the stability of geocell protection of slope is obtained based on Correlation Degree. Analysis results show that based on comprehensive consideration of subjective factors and objective factors, this method is effective and agrees well with engineering practical.
