The skill-related physical fitness evaluation index system is an important reference basis for evaluating the competitive level of tennis players. At present, there are few studies on the skill-related physical fitness evaluation index system of Chinese young male tennis players. Based on the characteristics of tennis events and the sensitive period of the development of young tennis players skill-related physical fitness variables, this study uses literature methods, Delphi method and other research methods to construct an evaluation index system for Chinese young male tennis players skills related physical fitness. The results show that: Chinese young male tennis players skill-related physical fitness includes six first-level indicators including speed, strength, endurance, agility, flexibility, and power, 11 second-level indicators such as aerobic endurance, anaerobic endurance, upper body power, and lower body power, etc. 16 third-level indicators such as the hexagon test, beep test, sit and reach, etc.

The Index System

Effectiveness evaluations are one of the important ways to guide grid investment and to improve investment efficiency. Improving the effectiveness of grid investment evaluations is studied based on the optimization of the investment evaluation index system and the utility evaluation model. The index system is optimized by establishing an evaluation index system of grid investment effectiveness, considering the redundancy between the indices, and constructing an ISM-DEA model. The utility function model was introduced to fully consider the different risk appetites of decision-makers, and a utility evaluation model that takes risk appetite into account was established. An improved weight integration model based on multiobjective optimization was established by considering the minimum deviation and the trend-optimal objective function when setting the index weights. The calculation results show that the feasibility of the index system optimization model and utility evaluation model constructed in this study is verified under the premise of satisfying the assumptions. By adjusting the risk preference coefficient of decision-makers, the dynamic optimization of the grid investment utility evaluation results can be realized.
