Abstract

Faster-than-real-time simulation (FRTS) is used when attempting to reach conclusions for the near future. FRTS experimentation proves to be the most demanding phase for conducting FRTS, since it requires concurrent monitoring and management of both the real system and the simulation experiments. Having previously introduced a conceptual methodology and specification for conducting FRTS experiments, we now propose an implementation framework, based on the Real Time Unified Modeling Language (RT-UML). The derived RT-UML model includes specific timing attributes and is independent of the application examined via FRTS. Thus, implementation of FRTS program modules can be analyzed and realized, following the guidelines of this model, ensuring the reliability of the results within predetermined time frames. A pilot application regarding FRTS implementation based on the proposed RT-UML model and related experience is also discussed in the paper.
