Run-Time Fault Detection Using Automatically Generated Fault Tree Based on UML

Systems become more complex and bigger, therefore management effort and costs for management are increasing rapidly. Especially enormous human and financial damages are caused if it fails to perform assigned duties, the ability to recover and to identify the cause is essential. In this paper, a method to identify faults in runtime is proposed. Fault tree is automatically generated from the system design documentation. These methods minimize human mistakes and missing information while generating fault tree. We show that generated fault tree could be used for fault localization in run-time, and monitoring overhead could be reduced by example.
