Abstract: The information service quality of C2 system determines the effectiveness of C2 system to some extent.The quality elements that may influence the effectiveness of the information service were analyzed,such as information quality,service function and service performance.Then the evaluation indexes were put forward for the information service quality in C2 system.According to the index characteristics,three kinds of evaluation methods were designed including quantitative evaluation,semi-quantitative evaluation and qualitative evaluation.Furthermore,the evaluation algorithms and steps of some typical indexes were provided and discussed in detail.The results can support the C2 users to evaluate the information service quality with theory and methods.
