The Sim4Sys Method

The Sim4Sys method is built around a structured workflow that supports the modeling, simulation, and validation of systems throughout their development. It relies on two complementary environments:

• Sim4Sys Designer focused on the functional and behavioral modeling of the system.
• Sim4Sys Virtual Bench used for interactive simulation and scenario validation in a virtual environment.

This method is particularly valuable because it encourages early integration of tests scenarios and requirements traceability, supports automation at key steps (document generation, validation, diagrams ...) and includes engineers throughout the process.

The diagram below illustrates this integrated process, showing how modelling and simulation environments work together to support model-driven system engineering.
