A lightweight approach to the concurrent use and integration of SysML and formal methods in systems design.

Increased systems complexity and ubiquitous computing drive the need for improved systems design. Model-based systems engineering using general purpose languages such as SysML, is a well-established response to this challenge. However, for systems where correctness-by-construction is critical, formal methods are often also deployed. This is a significant undertaking often involving complete model translation. We address this problem by developing a novel requirements interchange system, presented as a SysML model library, to guide the concurrent use of SysML and formal models without requiring complete model translation.
