Production automation systems are often complex systems as the behavior of the overall system cannot easily be predicted from the behavior of the subsystems. Thus simulation is used to study the behavior of complex production automation systems. In addition to the accuracy of the simulation the system performance is an important issue, particularly if many parameter variants for system behavior are to be tested. Parameters for assembly lines are, for instance, scheduling strategy and failure handling strategy. SW testing investigates the quality of the product or service under test. The goal...
