In this paper, the authors introduce librbd, a C library for time-dependent reliability evaluation of Reliability Block Diagrams (RBDs). The library achieves comparable or even better accuracy and efficiency than other established tools by combining different modeling formalisms and solution techniques at different system levels.
Reliability Block Diagrams (RBDs) are widely used in reliability engineering to model how the system reliability depends on the reliability of components or subsystems. In this paper, we present librbd, a C library providing a generic, efficient and open-source solution for time-dependent reliability evaluation of RBDs. The library has been developed as a part of a project for reliability evaluation of complex systems through a layered approach, combining different modeling formalisms and solution techniques at different system levels. The library achieves accuracy and efficiency comparable to, and mostly better than, those of other well-established tools, and it is well designed so that it can be easily used by other libraries and tools.
