中文摘要：

在C4ISR系统能力需求开发过程中,非功能性需求建模是一个难点,在综合模糊统一建模语言（unified modeling language,UML）与云模型的基础上,提出了一种面向C4ISR系统效能需求的建模与分析方法。首先,从系统效能需求建模入手,提出一种兼顾C4ISR系统功能和效能综合建模的需求分析框架,并通过扩展传统的UML来提高其领域适用性,实现对效能等模糊信息的建模。其次,结合该框架设计了一种效能云模型逆向生成算法,并提出基于云模型的综合效能评估函数构建方法,可以实现对系统效能的定量分析,评价系统完成使命任务的效果。最后,通过一个精简的区域防空系统案例验证了方法的可行性与正确性。

英文摘要：

command,control, communication, computer, intelligence, surveillance, resonance） systemic efficiency analysis. Amodeling and analysis method to C4ISR system for efficiency requirements based on the fuzzy unified modelinglanguage （UML） and cloud model is proposed. Firstly, a requirements analysis framework is suggested, whichcan define integrated requirements of both system functions and efficiency？ and the classic UML is extended toimprove the domain applicability. And the fuzzy information can be modeled by the fuzzy UML. Secondly, abackward generator arithmetic of efficiency cloud model is designed, and a constructible method for efficiencyevaluation function based on the cloud model is suggested, which can facilitate to make quantitative analysis forthe C4ISR system and describe the complete effect of the mission. Finally, a crisp case of air defense is used tofacilitate and demonstrate the correctness and feasibility of this method.
