A Battlefields Survivability Evaluation Model of Operation Information System Based on Rough Set and Multi-level Grey Theory

According to the analysis of problems existed in grey evaluation model of operation information system assessment, Based on the rough set theory, a grey comprehensive evaluation model Based on rough set attribute reduction. This paper discusses the evaluation process of the model, the multi-level and the establishment of a operation information system survivability evaluation index system, has carried on the example analysis combining the actual operation information system. The results show that, the rough set theory and the grey comprehensive evaluation model Based on multiple levels, in the premise of not affecting the key information, to maximize the elimination of redundant information, eliminate dependency relationships between indexes in whole or in part, reduces the influence of subjective factors in evaluation, improve the effectiveness and objectivity refers to essential information system evaluation conclusion. Provides the theory basis for the actual use of scientific evaluation information command system.
