To solve acquired the membership degree in fuzzy evaluation. we use correlation function in extension theory to calculate the degree of association between evaluation indicators and fuzzy scales, and then the degree of association is done standers conversion and normalized processing,, getting the membership value of evaluation matrix in fuzzy comprehensive evaluation. Comprising traditional statistical methods and expert evaluation method, the membership value of evaluation matrix which is gat through correlation function method of extension theory is more simple and reasonable. Comprehensive evaluation value is got from Calculating linear weighted between evaluation matrix and the index weight coming from analytic hierarchy process. Finally, using two type of home made NC machine tools as example to do the practical application study of the proposed method, the results show that this method can give the reasonable evaluation.

The evaluation of technological process in CAPP based on fuzzy mathematics was explored and researched. Aiming at fuzzy auto-evaluation，factors set, weight set and assessment set were built with the applying membership function and weight of fuzzy mathematics .Then the evaluation matrix of technological process was received through fuzzy matrix calculation. According to the principle of maximum membership degree, the grade of technological process was determined. The optimum technological process was obtained on the comparison among the grades of processes, giving an example of the automatic fuzzy comprehensive evaluation for the disc-like component.

According to the UNWTO, within 4 to 5 years, the proportion of tourism e-commerce in e-commerce will reach 20%-25%. The purpose of this paper is to improve the inadequacy of tourism e-commerce in customer experience, to conduct customer e-commerce satisfaction surveys, and to draw customers' dissatisfaction with tourism e-commerce. The experimental results show that the overall customer satisfaction is 2.6128. According to the division of the scale vector, the overall satisfaction of the travel e-commerce customers is generally level. The first-level fuzzy comprehensive evaluation is 0.0967, 0.1696, 0.3366, 0.2469, 0.502. According to the principle of maximum membership degree, the evaluation grades of R3 and R5 in the first-level fuzzy comprehensive evaluation are “unsatisfactory,” that is, the tourism-supporting services and contract-performance services become the main factors affecting customer satisfaction. In order to improve customer satisfaction, the tourism e-commerce platform should strengthen the management of tourism-supporting services and contract-fulfillment services.

In this paper, we develop an automatic system which could help us to select or evaluate the most suitable target from a variety of candidates. Above all, we carry out an analytic hierarchy process including 3 levels with different factors. After combing with fuzzy comprehensive evaluation, we rank the candidates with final scores. More specifically, taking the selection of the best coaches of football in American universities as an example, a hierarchical structure it built, with coaches’ comprehensive capacity being the target level, their technical skills, competition records, and personal influence being criteria level, coaching experience, teams’ improvement factors, win-loss percentage, participation in highly-demanding competitions and awards of coaches being the corresponding index level. Then, we use cluster analysis to determine threshold of each index, and combine trapezoidal distribution function with fuzzy comprehensive evaluation to obtain the membership degree of the following five sectors: fully equipped, equipped, basically equipped, poorly equipped, not at all equipped. After scoring each coach, we obtain the final rank

This paper mainly studies the application of intelligent lighting control system in different sports events in large sports competition venues. We take the Xiantao Stadium, a large­scale sports competition venue in Zaozhuang City, Shandong Province as an example, to study its intelligent lighting control system. In this paper, the PID (proportion – integral – derivative) incremental control model and the Karatsuba multiplication model are used, and the intelligent lighting control system is designed and implemented by multi­level fuzzy comprehensive evaluation model. Finally, the paper evaluates the actual effect of the intelligent lighting control system. The research shows that the intelligent lighting control system designed in this paper can accurately control the lighting of different sports in large stadiums. The research in this paper has important practical significance for the planning and design of large­scale sports competition venues.
