abstract = "This paper addresses issues related to the software
design in distributed real-time automation systems.
Beside the influence of the real-time operating system
and the behaviour of the technical process, the
properties of the communication network play an
important part for the temporal correctness of the
software design. In consideration of the enormous
complexity, an attempt to improve the software
correctness concerning the temporal behaviour by a
three layered Simulation Based Analysis (SBA) System is
presented. The SBA system automatically evaluates
timing requirements, which can be specified by a
problem adapted language, and estimates the system's
behaviour in both the best case and especially the
worst case by using evolutionary strategies. The SBA
system is currently implemented into a prototype.",
