In order to get an optimized combination of the economic and technology indicators for various communication modes in distribution automation systems, this paper proposes an optimization mathematical model tbr the wireless communication modes used in the distribution automation systems based on the interval numbers decision theory. The subjective and objective weights are calculated by the linear programming theory and the maximum deviation method respectively, and then the comprehensive weight is calculated by integrating the subjective weight and objective one using the addition fusion principle. The double base points ranking method is introduced to define the relative optimal scheme, the relative worst scheme, the absolute optimal scheme and the absolute worst scheme. Further, by calculating the degree value of the selected communication mode, the mode can scientifically select a wireless communication mode for distribution automation system, and can provide a reference lbr the decision-maker to choose the optimal communication mode. Through a practical example analysis and comparison of the existing methods, the validity and superiority of the model is verified.
