Abstract: System signature shows powerful features such as system reliability analysis, system design and system life comparison. The difficulty of signature calculation increases exponentially with the system architecture being more complex and the increase of the component number. For systems with sequential failure effect, we propose a novel approach to compute the signature. A concept called vector for number of modular failure orderings is defined and the modular decomposition signature method is proposed based on the vector. It is efficient for the signature computation of the systems with a large number of components. As applications of the method, the signature formulas of modular parallel systems, series systems and standby systems are investigated. The signature results are more concise compared with the previous methods. Numerical examples and applications are provided to demonstrate the proposed methodology.
