Abstract
Dynamic Fault Trees (DFT) extend standard fault trees
by allowing the modeling of complex system components’
behaviors and interactions. Being a high level model and
easy to use, DFT are experiencing a growing success among
reliability engineers. Unfortunately, a number of issues still remains when using DFT. Briefly, these issues are (1) a lack of formality (syntax and semantics), (2) limitations in modular analysis and thus vulnerability to the state-space explosion problem, and (3) lack in modular model-building.
We use the input/output interactive Markov chain (I/O-IMC)
formalism to analyse DFT. I/O-IMC have a precise semantics
and are an extension of continuous-time Markov chains
with input and output actions. In this paper, using the I/O-IMC framework, we address and resolve issues (2) and (3)
mentioned above. We also show, through some examples,
how one can readily extend the DFT modeling capabilities
using the I/O-IMC framework.
