“…To facilitate this type of modelling for detectability, HiP-HOPS has been extended with the ability to perform non-coherent analysis (Sharvia, 2008). The analysis of noncoherent fault trees in HiP-HOPS is implemented through an extension to MICSUP algorithm to allow iterated Consensus.…”

“…In aircraft industries, the symptom has many features for only one data source, that is, the possible responses of test may be more than one [3]. So the diagnostic dictionary for representing the relation between the faults and the test available to a system will not be a binary test matrix [4].…”

The excellent maintainability is the significant characteristic of the aero-engine, which ensures the maintenance high quality, high efficiency and low cost, but values of one attribution of aero-engine fault are more than one. In this paper, we consider a multi-valued test sequencing (MVTS) problem, in which a test may have an arbitrary number of possible outcomes denoting different behaviors. The multi-valued test sequencing problem can be solved through dynamic programming to find the optimal test sequence, but the time and space is large. In order to deal with this problem, we propose multi-valued AO* algorithm, called MVAO*, based on multi-valued heuristic evaluation function (MVHEF) in the AO*. With one aircraft gas turbine engine, we demonstrate that MVAO* is efficient and effective for optimizing test sequences problem with multiple test responses.

“…With respect to the previous example, if components and have failed, then should be the last component to be repaired to avoid system failure. Furthermore, PI identification allows taking additional counteracting measures to prevent system failure, for example by forcing the failure of component when components and have already failed [6].…”

A Visual Interactive Method for Prime Implicants Identification

2015

We propose a visual interactive method for the identification of the Prime Implicants (PIs) of dynamic non-coherent systems. Visual interactive methods integrate mathematical and symbolic models with runtime interaction and real-time graphic display, which allow visualizing the underlying physical relationships among process parameters. The proposed method is based on a parallel coordinates data mining tool that relies on an innovative pruning procedure which, on the basis of a proper selection of characteristic features of the accident sequences, retrieves the PIs among the whole set of Implicants in terms of process parameters values and/or components failure states. The method is exemplified on an artificial case study and, then, applied for the dynamic reliability analysis of the Airlock System (AS) of a CANDU reactor
