Research on Power Amplifier Type Selection of Urban Rail Broadcasting System Based on VIKOR Evaluation Method
This paper first introduces the main function and system structure of urban rail public address system,and then introduces several conventional comprehensive evaluation methods of selection decision.By analyzing the influencing factors of power amplifier selection,VIKOR method is proposed to realize selection decision evaluation.This paper introduces the procedure of VIKOR method in detail,and creates the evaluation index system of the selection problem according to the index characteristics.Finally,the original data matrix of power amplifier index is created through practical cases,and the optimal ranking of power amplifier type selection is obtained through calculation.
