Research on Fuzzy Comprehensive Evaluation of Track and Field Project Level in China

Abstract

After the reform and opening up, China's sports career has been rapid development, of which track and field events as an important part of sports, sports undertakings in China has a great role in promoting. Track and field events consist of a number of events, with the largest number of track and field events at the olympics. This paper uses fuzzy comprehensive evaluation method based on entropy method for our country's track and field project comprehensive evaluation, selection of track facilities proportion, the proportion, track and field athletes winning percentage, 100m record as the evaluation factors. Secondly, establishing the membership function of each evaluation factor in subjection degree lower semi gradient. We can get the data of each factor fuzzy set membership value, based on the application of entropy method to influence, the greater the effect of the principle of weight calculation of each factor value, get the weight set; finally using matrix multiplication weight set and fuzzy set comprehensive evaluation fuzzy matrix synthesis, draws the conclusion: our country's track and field the project is in the middle level, the infrastructure also need to increase efforts to improve, in addition to our university athletes selection system needs to be adjusted It pays great attention to the track and field sports quality of college students, so as to improve the level of track and field in china.
