Proposal for a New Hybrid Explosive Atmosphere(ATEX) Risk Assessment Approach Using RiskPriority Number and Analytical Hierarchy ProcessMethod. Nuclear Technology [Internet]. In Press.
Publisher's VersionAbstractThis study aims to highlight the importance of evaluating explosive atmosphere (ATEX) risks and to
propose a novel, more accurate and comprehensive risk assessment method compared to traditional existing
approaches. To address the limitations of traditional ATEX risk assessment methods, this study introduces a new
approach based on three key parameters: occurrence, detection, and severity. These factors are combined using
a weighted sum (WS) formula to calculate a modified risk priority number (RPN), enhanced by the analytic
hierarchy process.
This hybrid methodology provides a more precise and reliable assessment of ATEX risks. Moreover, the
findings of the proposed WS-RPN method (and its ATEX-specific version, WS-RATEX) demonstrate superior
accuracy and lower duplication rates compared to conventional risk assessment techniques. A sensitivity
analysis confirms the robustness, stability, and reliability of this approach, making it a valuable tool for
quantifying ATEX risks.
It is evident to say that WS-RPN represents a significant advancement in ATEX risk assessments. By
integrating a refined calculation model, and factoring in occurrence, detection, and severity, the latter ensures
a more systematic and reliable evaluation. Thus, with improved risk prioritization, this approach not only enhances
industrial installations’ safety but also serves as a more effective alternative to traditional assessment methods.

Management of recurrent problems in industrial companies: a case study. International Journal of Business Excellence [Internet]. In Press.
Publisher's VersionAbstractAll industrial companies are confronted with recurrent problems that have an impact on their overall performance. Despite this, many companies have not developed strategies for managing these problems. This article illustrates the case of an Algerian company where an organisational management strategy for these recurrent problems is proposed. This strategy focuses on the sustainability of a continuous improvement project to reduce these problems. The expected results of this strategy lie in the gradual elimination of recurrent problems and, consequently, an increase in the efficiency of company processes. Hence, there is the possibility of achieving performance in productivity.
