基于模糊云模型的C4ISR系统效能需求建模与分析方法

摘要

The modeling problem of non-functional requirements plays a significant role in C4 ISR (com-mand,control,communication,computer,intelligence,surveillance,resonance)systemic efficiency analysis.A modeling and analysis method to C4 ISR system for efficiency requirements based on the fuzzy unified modeling language (UML)and cloud model is proposed.Firstly,a requirements analysis framework is suggested,which can define integrated requirements of both system functions and efficiency,and the classic UML is extended to improve the domain applicability.And the fuzzy information can be modeled by the fuzzy UML.Secondly,a backward generator arithmetic of efficiency cloud model is designed,and a constructible method for efficiency evaluation function based on the cloud model is suggested,which can facilitate to make quantitative analysis for the C4 ISR system and describe the complete effect of the mission.Finally,a crisp case of air defense is used to facilitate and demonstrate the correctness and feasibility of this method.%在C4 ISR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（uni-fied modeling language，UML）与云模型的基础上，提出了一种面向 C4 ISR 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 C4 ISR 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。
