  When using multiple software tools to analyze, visualize, or optimize models
in MBSE, it is often tedious and error-prone to manually coordinate the
execution of these tools and to retain their respective input and output data
for later analysis. Since such tools often require expertise in their usage as
well as diverse run-time environments, it is not straightforward to orchestrate
their execution via off-the-shelf software tools. We present RCE, an
application developed at the German Aerospace Center that supports engineers in
developing and orchestrating the execution of complex tool chains. This
application is used in numerous research and development projects in diverse
domains and enables and simplifies the creation, analysis, and optimization of
models.
