A Novel Modeling and Analysis Approach to Efficiency Requirements for System of Systems

To solve the problem that the classical UML is lack of capability to model the fuzzy information for the C4ISR system, the paper proposes a novel modeling and analysis method based on fuzzy cloud model. It suggests a requirements analysis framework, which can define integrated requirements of both system functions and non-function, and extends the classic UML to improve the domain applicability. Then, it designs backward transformation algorithm of efficiency property and suggests a constructible method for efficiency evaluation function. Finally, the feasibility of the proposed approach is illustrated by using a military example.
