Ontology-based knowledge representation of failure mode and effect analysis on Electric/Electronic Architecture modeling conforming to the ISO 26262

摘要

In this paper, we propose knowledge representation of Failure Mode and Effect Analysis (FMEA) on Electric/Electronic Architecture (EEA) tailored to ISO 26262. FMEA, EEA, and ISO 26262 are composed of abstract and concrete data. Description and representation of abstract and meta models are complex. Indeed, to simplify and feasibly represent the data for software/hardware development of the EEA, we approach the knowledge representation of the FMEA for the concrete and abstract models of EEA using ontology. With the ontology, FMEA, EEA, ISO 26262, and combination of the three aspects can be presented using concrete models, and are able to be defined in the form of class models. These class models will be occupied for the development of the software aspect of FMEA for EEA accommodating the ISO 26262. Hence, this type of representation is considered to an adequate model to represent the abstract, concrete and meta models of FMEA for EEA conforming to ISO 26262.
