Self-optimization in mechatronic systems often is achieved by the change of their component structure during runtime. As their operation often is safety-critical we need to know which error combinations lead to hazards. By now our hazard analysis considers no time and only individual component structures without the transitions between them. Consequently, we get inaccurate results when analyzing self-optimizing systems. We propose to improve our current hazard analysis considering time and the system behavior during the change of the component structure. This is achieved by the probabilistic model checking of the system behavior and the analysis of the structure transformation.
