Lighting system scheme selection is an important part of infrastructure construction. This paper proposes an improved radar chart evaluation method for lighting system performance evaluation. First, to solve the problem of other weight scale methods' inaccurate calculation, Pitman's closeness measure in exponential form is used to determine the weight of the lighting system performance evaluation index. Second, a comprehensive performance evaluation model, applying the average area, average girth, and average eccentricity of the radar chart, is presented to solve the problem of inconsistent evaluation results due to the different orders of indicators. Finally, an example is given to verify the correctness and rationality of the proposed model. The research work provides scientific guidance for lighting system scheme selection.
