Abstract
This paper proposes a semi-automatic methodology to assist the user in creating surveys about FMEA and Risk Analysis, based on a customized use of the tools for semantic analysis and in particular a home-developed syntactic parser called Kompat Cognitive. The core of this work has been the analysis of the specific FMEA-related jargon and its common modalities of description within scientific papers and patents in order to systematize the linguistic analysis of the reference documents within the proposed step-divided procedure. The main goals of the methodology are to assist not skilled in the art users about FMEA during the analysis of generic and specific features, by considering large moles of contributions in restricted amounts of time. The methodology has then been tested on the same pool of 286 documents, divided between 177 and 109 patents, manually analyzed in our previous survey, in order to replicate part of its classifications through the proposed new modality. In this way we evaluated the abilities of the methodology both to automatically suggesting the main features of interest and to classify the documents according to them.
Highlights
Since its introduction in 1949, FMEA had a great following both in industrial and scientific community as testified by the vast multitude of related documents from scientific and patent literature: to date, we have more than 3600 papers only in Scopus DB and 146 patents in Espacenet DB, just looking for one single keyword “FMEA”, without synonyms, with a trend of constant growth over the years
We identified generic verbs (e.g. Improve, Ameliorate, Reduce) that are generally used to introduce the goals of the proposed interventions, which in turn are expressed by generic terms, or strategies for improving FMEA tasks, which are instead expressed through FMEArelated terms (e.g. Failure, Modes, Effects)
New methods to be integrated into FMEA (TRIZ, Maintenance management tools, etc.) (Liu et al, 2011)
Summary
Since its introduction in 1949, FMEA had a great following both in industrial and scientific community as testified by the vast multitude of related documents from scientific and patent literature: to date, we have more than 3600 papers only in Scopus DB and 146 patents in Espacenet DB, just looking for one single keyword “FMEA”, without synonyms, with a trend of constant growth over the years. In order to be able to orientate among the many contributions the surveys proposed in literature can play a fundamental role, even if they are limited in the number of considered documents by never exciding one hundred of only scientific papers from journals. Other authors focused on analyzing specific kinds of application of FMEA approach. Dale and Shaw (1990) studied how 78 companies of the United Kingdom motor industry apply FMEA by identifying some common difficulties such as time constraints, poor organizational understanding of the importance of FMEA, inadequate training and lack of management commitment
