A hybrid integrated multi-criteria decision-making approach for risk assessment: a study of automotive parts industry

Abstract

PurposeThis paper aims to enable the analysts of reliability and safety systems to evaluate the risk and prioritize failure modes ideally to prefer measures for reducing the risk of undesired events.Design/methodology/approachTo address the constraints considered in the conventional failure mode and effects analysis (FMEA) method for criticality assessment, the authors propose a new hybrid model combining different multi-criteria decision-making (MCDM) methods. The analytical hierarchy process (AHP) is used to construct a criticality matrix and calculate the weights of different criteria based on five criticalities: personnel, equipment, time, cost and quality. In addition, a preference ranking organization method for enrichment evaluation (PROMETHEE) method is used to improve the prioritization of the failure modes. A comparative work in which the robust data envelopment analysis (RDEA)-FMEA approach was used to evaluate the validity and effectiveness of the suggested approach and simplify the comparative analysis.FindingsThis work aims to highlight the real case study of the automotive parts industry. Using this analysis enables assessing the risk efficiently and gives an alternative ranking to that acquired by the traditional FMEA method. The obtained findings offer that combining of two multi-criteria decision approaches and integrating their outcomes allow for instilling confidence in decision-makers concerning the risk assessment and the ranking of the different failure modes.Originality/valueThis research gives encouraging outcomes concerning the risk assessment and failure modes ranking in order to reduce the frequency of occurrence and gravity of the undesired events by handling different forms of uncertainty and divergent judgments of experts.

A Neuro-Fuzzy Risk Prediction Methodology in the Automotive Part Industry

“…However, the risk assessment for the failure modes can be vastly dissimilar. Third, existing evaluation methods are complicated, and it is difficult to assess the three risk parameters in most cases [1][2][3].…”

An ensemble learning strategy for multi‐source hydrogen embrittlement data by introducing missing information

“…These materials, which include iron, steel, nickel, and titanium‐based alloys, have a wide range of applications in industrial environments. The migration and accumulation of atomic hydrogen as well as its interaction with metal alloys will have a profound effect on the properties of various materials [1–4] . The penetration of atomic hydrogen into materials can lead to a decrease in the strength and plasticity of metallic materials, a phenomenon known as hydrogen embrittlement [5] .…”
