Modern process system can be regarded as multi-medium interacted heterogeneous networks comprised of material transportation, power supply and control information exchange, in which substance like material, energy and information coexist and interact. Thus fault diagnosis and safety analysis for complex process system based on homogeneous network theory should be improved to hold multi-medium interacted...
Bayesian network is one of the most effective theoretical models applied in the fault diagnostic decision. In order to realize the computer-aided construction of the Bayesian network for diagnostics, this paper proposes a simple, yet comprehensive failure knowledge representation model combined with the structure decomposition of the complex system. Using the polychromatic sets theory, the rock-bottom...
Failure modes and effects analysis (FMEA) is a traditional safety analysis method that has a worldwide recognition across many industries. However, there are documented limitations to the technique, which make it difficult for direct conversion to the diagnosis models. This paper aims to contribute to the reuse of FMEA knowledge through a novel knowledge modeling approach. Taking the structure model...
