Main Description

The task Extrapolate time budget influencing properties addresses a problem that occurs in particular at high abstraction levels. The information needed for finding the sought time budget properties is not present at that level, and it is not found among the transformed properties. In such cases, it might be necessary to conduct rapid prototyping to quickly obtain a temporary extrapolation of the system models that will be developed in later development phases at lower abstraction levels. The analysis is then performed on these lower-level temporary models in the same way as in the task Determine time budget properties. The result is then transformed back to the model at the original abstraction level and the temporary models are discarded. Naturally, such an approach will not give 100% accurate results, but will still give a hint on which values are reasonable. In order to make this strategy feasible and efficient, it is important that all steps, including the extrapolation, are automatic.
