AbstractThe selection of basketball players should highlight their specific characteristics and proceed according to the essential laws of basketball. When the acquired training level becomes closer and closer, and is more and more conducive to the control of the entire training and competition, the selection of the standard paradigm of basketball players plays a key role. At present, the existing evaluation methods of basketball players are limited to the human experience of coaches, and there is a lack of further information evaluation methods. This article discusses a new type of basketball player evaluation scheme that combines wireless network and machine learning methods. First, the wireless sensor network is used to perceive basketball players' performance on the court and record various evaluation indicators. Secondly, establish a player value evaluation model through improved Bayesian algorithm and fuzzy comprehensive evaluation methods. Finally, after relevant tests and comparisons with the coaches' results, the model showed better evaluation results and a fairer value distribution.

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.

Problems on resource and environment are found through the analysis of traditional stamping process. The theory of variation weight fuzzy comprehensive evaluation method is introduced and the evaluation model has been built. Then the weight-constant and weight-variation fuzzy comprehensive evaluation methods are used to evaluate the selection of punching machines. The conclusion proves that the variation weight makes the evaluation more scientific and accurate.

Construct the fuzzy comprehensive evaluation model on geological exploration project supervision index system, and be able to provide reference for geological and mineral exploration relating departments to make decisions. The comprehensive evaluation model is proven to be effective by analyzing some index selection solutions. Apply fuzzy comprehensive evaluation (FCE) method to the selection of geological exploration project supervision indexes, analyze the weights of the various factors which affect the indexes first, then perform fuzzy comprehensive evaluating on the indexes to be determined, and finally classify the evaluated objects and select corresponding indexes according to evaluation results. The method resolves the issues of strong subjectivity and results lacking of quantization which are caused by selecting indexes by simple analogy, and has higher scientificity and practical values.

Logistics supplier selection is the source of wind power manufactures enterprise product quality assurance,while the evaluation and selection of suppliers are affected by a number of uncertainty factors. In order to be more accurate and comprehensive evaluate the logistics supplier of wind power manufactures enterprise, a set of vendor evaluation index system is established in this paper. For the status quo of wind power manufactures enterprise directly scoring, an evaluation model is proposed which use fuzzy comprehensive evaluation method to evaluate and select logistics supplier for wind power manufactures enterprise. The actual case shows that the method can be objective and accurate selection of suppliers and overcome the shortcomings of the previous evaluation methods.

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.

In the College, performance evaluation system is directly related to the harmonious development of the school. Taking into account the factors in the evaluation system is fuzzy, so this paper uses fuzzy comprehensive evaluation model. But the model is too subjective, so this paper combines neural network and data envelopment analysis method, which ensures that fuzzy comprehensive evaluation model is reasonable and scientific, and good school development and teacher self-interest. The performance assessment process, not only enables the combination of qualitative and quantitative analysis, but also fair and reasonably reflect the achievements of teachers, while this method is easy to use, wide application, and can be well applied in practice.
