Using Mathematical Formalisms for Efficient Systems
The OMG's Mathematical Formalism Domain Special Interest Group (Math DSIG) looks to mathematically optimize systems via model-based systems engineering (MBSE). Complexity in modern systems poses significant challenges to the efficiency and assurance of developing useful models for product and service delivery to market. Mathematical systems modeling simplifies the representation of complex systems and facilitates the analysis and forecast of system behavior. There is a significant opportunity for MBSE to reduce the complexity of system architecting and design while improving the scientific quality of the models developed. The Math DSIG can help redefine your system's efficiency.
MISSION:
Collaboratively work with OMG groups to achieve the following goals:
- Develop mathematical formalisms for OMG model based frameworks and standards
- Develop model transformations using mathematical formalisms that will enable systems architects to compose higher level model transformations more easily from more granular model transformations, thereby reducing the complexity of system design and analysis
- Develop foundational formalisms that underly MBSE and can be expressed via OMG model-based standards
The first two goals resulted in the adoption of UPR, which was subsequently applied to the commercialization of wireless charging for automotive electric vehicles. Subsequently, initial work began on the UPR Revision Task Force. The group is re-organizing to pursue the third goal based on recent and ongoing advances in academic research and commercialization.
The Math DSIG brings unique expertise and experience in advanced research as well as the commercialization of complex systems using mathematically based MBSE.
