A Coupling Analysis Method for Airborne Software Based on Requirement Model

In order to measure the data coupling and control coupling between system components and to clarify the dependency relationships among variables in the requirements, this study offers an airborne software requirements coupling analysis approach based on the requirement model. A data coupling and control coupling analysis method based on the VRM model (Variable Requirement Model) is presented in the paper, which uses a coupling measurement method based on hierarchical dependency relationships among variables. Variable relationships are defined as an n-ary dependency tree structure, and weights are assigned using algorithms. This study helps with complex system design and raises the standard and dependability of creating airborne software.
