Many evaluation factors are involved in dam risk consequences comprehensive evaluation, which exist plenty of uncertainty and correlation between each other. Combined the five methods, such as linear weighted sum method, fuzzy mathematics method, matter element method, gray correlation method and principal component method with dam risk consequences comprehensive evaluation, establishing five dam risk comprehensive evaluation models, applying to the level evaluation of Changlong Reservoir, Xialan Reservoir, Shibikeng Reservoir, Longshan Reservoir, Lingtan Reservoir successfully.

This spring a serious drought occurred in some areas of China, which had a great impact to local production, living and economic development. For this severe problem, earth-rock dam’s risk consequence evaluation model under drought condition was proposed, and factors of earth-rock dam risk consequence were analyzed and summarized, using principal component analysis to establish comprehensive evaluation model of earth-rock dam’s risk consequence under drought condition.

Use of the advantages of different mathematical model, and the integrated use of, has become a development trend to construct the new evaluation model. This paper puts forward a kind of multi-level comprehensive evaluation model based on the combination of principal component analysis, independent factor analysis and different distance clustering analysis. To construct a three levels analytic hierarchy comprehensive evaluation index system, and using patent information in an area 20 colleges and universities as an application case, to verified the feasibility of this new type of comprehensive evaluation model and practical. The evaluation parameters of the model are clear, easy application, evaluation results tally with the actual situation of degree is high. It is an effective platform that the various science and technology innovation ability evaluation provides. It is a basis for promote science and technology innovation ability.

Regional technological innovation ability is increasingly becoming the determining factor to attain an international competitive advantage for the areas, as well as to achieve regional economic growth and development. But in the same time of raising the regional technological innovation ability, it is also necessary to continuously improve the efficiency of regional technological innovation, so as to increase the resources efficiency. We evaluate the efficiency of regional technology innovation for China's 30 provinces and municipalities using comprehensive evaluation model combined principal component analysis and DEA. According to evaluation results, we think that the overall efficiency for regional technological innovation is at the low level, and most areas is at the stage of increasing returns to scale, that account for a common problem of insufficient investment in the process of regional technological innovation.

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.
