Abstract: There were various conventional modeling techniques with varied semantics for system reliability assessment, such as fault trees (FT), Markov process (MP), and Petri nets. However, it is strenuous to construct and to maintain models utilizing these formalisms throughout the life cycle of system under development. This paper proposes a unified formal modeling language to build a general reliability model. The method eliminates the gap between the actual system and reliability model and shows details of the system clearly. Furthermore, the model could be transformed into FT and MP through specific rules defined by a formal language to assess system-level reliability.
