Abstract:

The modeling problem of non-functional requirements plays a significant role in C⁴ISR(command,control,communication,computer,intelligence,surveillance,resonance) systemic efficiency analysis. A modeling and analysis method to C⁴ISR 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 C⁴ISR 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.
