摘　　要：战术数据链的指标体系中不仅包含可进行实测的定量指标,还有一部分不可量化的定性指标。针对该特点,提出用云理论解决其效能评估的问题,建立评估的指标体系,并将各指标用云模型表示,研究云理论评估的方法,在云重心加权偏离度的计算中,可能有某些指标对偏离度的贡献与实际意义正好相反,因此对云重心归一化公式进行修正。最后通过实例计算证明了修正后的方法评估可信度更高。The index system of tactical data link includes not only the quantitative index which can be measured practically,but also some qualitative indexes which can＇t be quantified.For these characteristics,this paper puts forward the method to use the cloud theory to solve the problem of effectiveness evaluation,establish the index system of evaluation,and uses cloud model to represent each index,studies the method of cloud theory evaluation.In the course calculating the weighted deviation degree of cloud center of gravity,there may be some indexes contrary to the practical meanings in the contribution to deviation degree,so the normalization formula of cloud center of gravity need to be modified.Finally,the practical example calculation proves that the modified evaluation method has better credibility.
