Abstract

The efficiency of communication system is the key factor for the operational capability of naval ship. Through analyzing the evaluation index of naval fleet's communication system, a satisfactory-degree based on efficiency evaluation model is founded by applying the grey relational analysis. The steps of the model include gathering index data based on index tree, constituting the reference sequence (optimal sequence), evaluating the difference sequence and the correlation coefficient, calculating the correlation degree and analyzing the index satisfactory-degree based on absolute correlation degree. The correlation degree is bigger, the scheme is better. On the other hand, the key index is found through calculating the absolute correlation degree. According to them, it provided a way for improving the efficiency of the communication system.
