SCS Workbench Components
System Concept Simulation for Concurrent Engineering 24/03/2015
Task Description
Model Development Model specification, implementation and debugging.
Model Import Import of model specification and implementation.
Simulation Composition Model instantiation and definition of relations (data exchange)
Simulation Scheduling Definition of model execution order and frequency.
Simulation Initialisation Definition of the Simulation Starting Conditions (Initial Values)
Simulation Execution
Simulation execution according to schedule providing means to control
the execution, e.g. manually or via a scripting. Simulation breakpointing.
Simulation Monitoring
Different kinds of presentation (1, 2 + 3D) and statistical preparation of
output data for system behaviour analysis during runtime.
Parameter Recording
Recording of parameters for post analysis. Full simulation recording
allowing for forward/backward replay of the simulation.
