Managing the development and deployment of complex systems can no longer depend on ad-hoc collections of independent documents. The ability to increase system performance and reliability, control costs, keep to schedules, and respect organizational governance rules requires a new approach. A new body of practice, Model-Based Systems Engineering (MBSE), is emerging to meet these needs.

MBSE starts with a “touchstone of truth”, a computer model of the system that:

  • Can federate all the information about the system,
  • Is accessible to every project participant,
  • Provides traceability as the model changes,
  • Enables analysis and simulation from the earliest stages, and
  • Can generate all required documents as needed.

No single software tool can meet all these needs. MBSE uses an integrated framework of existing engineering tools and data sources, centered on a core model. SysML (Systems Modeling Language) is a powerful vehicle for building and linking this core model. Intercax’s SLIM technology enables system engineers to drive workflows (simulation, trades, V&V) and federate engineering models directly from the SysML-based core model.

Intercax's SLIM Technology for MBSE

InterCAX helps its customers get started in MBSE by providing:

  • SysML-based simulation and integration products
  • Training in MBSE best practices, SysML and other subjects
  • Coaching to architect MBSE environments
  • Standard and custom software tools for an integrated MBSE environment
  • Consulting on model building, library creation and simulation

Customers can choose individual products and services, or a complete customized program, to get themselves up to speed quickly with an approach that meets their unique needs.
