(English Abstract)
System of Systems (SoS) is a large and complex system comprising independent constituent systems. Statistical Model Checking (SMC) techniques can be used to verify if the SoS achieves its goals or not. However, even if the SoS goal failure is detected using the SMC, finding a root cause of the SoS failure requires more cost than that of a system. One of the candidate solutions for reducing the debugging cost is to apply fault localization techniques on the SoS. However, existing fault localization techniques are designed to utilize testing results of a system. Thus, a method to utilize SMC results is needed to apply existing fault localization techniques to the SoS. In this study, we suggest six utilization methods of SMC results for SoS fault localization, and compare the performance of them on the emergency-response SoS. We found that the method based on the expectation value showed the best performance in the experiment.
