The forward approach has been used to prove the domain-independent principle of the well-ordered systems which are characterised by the smallest possible risk of failure. The inverse approach has been used to generate new knowledge related to the relationship of the equivalent elastic constants of elements arranged in series and parallel and the upper and lower bounds of the percentage of faulty components in pooled batches of components with unknown sizes.

In the proposed method a Mamdani fuzzy inference system is generated using two input parameters based on modified Nordic questionnaire and RULA. Fuzzy analytic hierarchy process is incorporated to calculate the weight of postural risk associated with each body part using the body part discomfort scale. Finally, weighted PRS of each body part is evaluated to identify the discomfort prone body parts for taking preventive strategies well in advance. To establish application potentiality of the proposed methodology a case study is performed for assessing weighted PRS of different discomfort prone body parts of female brick moulders engaged in several brick fields.

In view of potentially devasting consequences of exponential growth, the implementation of such a strategy is almost self-evident in this case. Less obvious is a formal explanation of why and when such a control strategy is necessary compared to traditional risk management approaches and which systems or organisations can benefit from it. Quantitative arguments are given based on the properties of heavy tail stochastic variables. Particularly, their single big-jump property provides the rationale to require a hierarchy of barriers for containment of a cascade of daughter events. The COVID-19 pandemic has vividly demonstrated how difficult it is to implement an appropriate control strategy under these circumstances. Concretely, it is shown that the spread of transport vectors in this case has heavy tail properties and consequently requires a defence in depth response. Journal: Int.

The concept of a 'robust company' outlined in strategic management terms in this paper is an integrative approach that combines findings from the areas of risk management, strategic management, corporate ratings, and insolvency research, as well as empirical capital market research. Robustness is the ability of a system to survive negative shocks while maintaining a defined minimum level of success (performance) in the long term. Research findings suggest that robust companies exhibit the following three key characteristics: high financial sustainability (a stable rating, low earnings risk), a robust strategy with stable strategic success potential as a driver of future financial performance and company value, and a high level of competence in dealing with risk, especially in making business decisions.

J. of Risk Assessment and Management Pages: 75-94 Issue: 1 Volume: 26 Year: 2023 Keywords: capability-based view; core competence; financial sustainability; resilience; risk; risk aggregation; risk analysis; risk management; robustness; strategy; uncertainty.

The purpose of the paper is to explore the range to which Slovenian members of the Emergency medical treatment (EMT) prehospital teams were familiar to the action recommendations of EMT teams in the occurrence of an AMOK situation. Further purpose was to inquire whether EMT teams are ready to confirm the link between awareness and their perceived competences. An online survey among 252 members of the EMT prehospital teams was employed, using a convenience sampling. The analysis shows that EMT team members agree that the regularity of joint drill with armed forces importantly affects their qualification for a correct action. But nevertheless, EMT members seem to be well-informed about the recommendations from a theoretical point of view. This study makes several contributions to the EMT teams' assessment of their readiness to respond in the case of an AMOK attack in a relatively safe European country. Journal: Int.
