Efficiency Evaluation of C~3I System Based on Improved Fuzzy Synthetic Evaluation Model
Hao Yongfeng · Electronics Optics & Control · 2011
There are several problems when using traditional fuzzy synthetic evaluation model to evaluate C3I system's efficiency.For example,it is not so objective because the weight of index is mainly depended on experience of experts by using AHP method;the differences between qualitative index and quantitative index were ignored when establishing evaluation matrix by using experts' judgments;and the resolution ratio is low because maximum membership principle was used when confirming the evaluation grade.To overcome the shortcomings,an improved fuzzy synthetic evaluation model was established,in which the index weight was amended objectively by using entropy technology;the established evaluation matrix was improved by classifying the differences between qualitative indexes and quantitative indexes;and the resolution ratio was improved by quantifying the evaluation grade by using interval value.The method was used in a certain C3I system for aerial defense,and its validity and advantages were verified.
