“…The current quantitative risk assessment methods are mostly based on fault tree analysis (FTA) [10][11][12], event tree analysis (ETA) [13][14][15], and criticality analysis (CA) [16,17]. The FTA method obtains the minimum cut set of the fault tree through calculation, finds out the weak links in the system, and develops appropriate risk control strategies for the weak links.…”

The risk assessment of the failure mode of the traditional machining center component rarely considers the topological characteristics of the system and the influence of propagation risks, which makes the failure risk assessment results biased. Therefore, this paper proposes a comprehensive failure risk assessment method of a machining center component based on topology analysis. On the basis of failure mode and cause analysis, considering the correlation of failure modes, Analytic Network Process (ANP) is used to calculate the influence degree of failure modes, and it is combined with component failure mode frequency ratio and failure rate function to calculate independent failure risk. The ANP model of the machining center is transformed into a topological model, and the centrality measurement of network theory is used to analyze the topology of the machining center. The weight of the topological structure index is measured by subjective and objective weighting methods, and then the importance degree of the machining center component is calculated. In this paper, the coupling degree function is introduced to calculate the importance of the connection edge, which is combined with the failure probability to calculate the failure propagation influence degree, and the component propagation failure risk is calculated based on this. Finally, the independent failure risk and the propagation failure risk of the component are integrated to realize the failure risk assessment of the component. Taking a certain type of machining center as an example to illustrate the application, compared with the traditional assessment method, the effectiveness and advancement of the method proposed in this paper have been verified.

“…Thus, one may use linguistic variables when assessing qualitatively or give intervals instead of exact crisp values in evaluating the data quantitatively. Therefore, the fuzzy set theory provides more descriptive studies [ 43 ]. What is also important is that decision-makers tend to believe that it is more certain to make interval judgments than fixed-value judgments.…”

The rising automation level and development of the Industry 4.0 concept in the mining sector increase the risk of cyber-attacks. As a result, this article focuses on developing a risk analysis method that integrates Kaplan’s and Garrick’s approach and fuzzy theory. The proposed approach takes into account the level of automation of the operating mining processes. Moreover, it follows five main steps, including identifying the automation level in a selected mine, definition of cyber-attack targets, identification of cyber-attack techniques, definition of cyber-attack consequences, and risk ratio assessment. The proposed risk assessment procedure was performed according to three cyber-attack targets (databases, internal networks, machinery) and seven selected types of cyber-attack techniques. The fuzzy theory is implemented in risk parameter estimation for cyber-attack scenario occurrence in the mining industry. To illustrate the given method’s applicability, seven scenarios for three levels of mine automation are analyzed. The proposed method may be used to reveal the current cybersecurity status of the mine. Moreover, it will be a valuable guide for mines in which automation is planned in the near future.

“…On the other hand, cooperative methodologies, incorporating qualitative and/or quantitative, hybrid, probabilistic, stochastic (STO) and/or deterministic (DET), multicriteria decisionmaking (MCDM) and/or Fuzzy-OSH, automated RAA techniques, etc., for instance the ones which combine QRA, HAZOP, XPA-HAZOP, DMRA, AHP, Fuzzy-AHP, FEAHP, TSP, PRAT, FTA, BIM, QFD, FMECA, PHSA, SCEA, FMEDA, LOPA and so forth, would be more effectual on the OSH field . In the last decade, many articles have continued incorporating DET methods (such as the well-known FTA) in OSH-RAA, such as: (i) the work of Mutlu et al (2019) [26], which integrates FTA with Failure-Mode and Effect-Analysis (FMEA) and BIFPET, (ii) the articles of Babaei et al (2018) [27] and Yasli and Bolat (2018) [28], which incorporate FTA in fuzzy OSH-RAA methods, (iii) the paper of Gul and Ak (2018) [29], which uses the cooperation of MCDM with FTA, (iv) the work of Fuentes-Bargues et al (2017) [30], which combines HAZOP with FTA in RAA of fuel storage-terminals, and (v) the article of Marhavilas et al (2020) [31,32], which mingles two different configurations of the MCDM method, initially the Analytical Hierarchy Processes 2021, 9, 1299 2 of 28 Process (the typical-AHP), and afterwards the Fuzzy-Extended AHP (the FEAHP), along with the Proportional Risk Assessment Technique (PRAT) and the analysis of Time-Series Processes (TSP), and lastly with the FTA, in sustainable constructions engineering projects. The reason for incorporating the above curt list of references, concerning these RAA techniques, is to show that all these techniques could be significant separate elements in RAA hybridization processes.…”

A collaborative framework by the synergy of Hazard and Operability (HAZOP) process and the Decision-Matrix Risk Assessment (DMRA) in association with safety-color mapping (SCM) is presented, in order to identify critical points and prioritize risks, and also to visualize the occupational safety and health (OSH) situation, at the workplaces (i) of a sour crude-oil processing industry (SCOPI), and (ii) of a measurement and regulatory station (MRS) in a gas transportation system (GTS), situated in Greece. Firstly, the conventional HAZOP analysis is executed in order to identify the potential fault causes of abnormal conditions (deviations) in the plants. The application of the DMRA-modus is valuable to rank the identified risks (hierarchy of risks). In view of the results, both of the HAZOP pattern (for identifying the hazards) and also the DMRA one (for assessing and ranking the risks), SCMs have been derived for the specific workplaces of the SCOPI and the MRS/GTS station, which could be a precious means for safety managers to appraise the urgency of investing limited budgets in measures preventing particular types of deviations, and also protecting the employees.
