“…Thus, the use of the ISOPT solution would make it difficult to implement a mathematical model that takes into account the correct execution of tasks, movement in VR space, and the sequence of tasks. At the same time, the mathematical basis of the algorithm, which consists in multiplying the level of risk present in the scenario and the correctness of the tasks, is popular among this type of application; in modern literature, it is described as the "Singapore method/model" (Kovačevića et al,2019;Goyal et al, 2022;Fejdyś et al, 2022).…”

Conducting a safe briefing is essential to educate aircraft maintenance personnel, who very often encounter various unexpected and dangerous incidents. Their reaction to situations should be quick and adequate. To train aircraft maintenance professionals who cannot be practiced in real life due to high cost, danger, time or effort, virtual training seems like an obvious choice. This paper is devoted to the development of a calculation algorithm for assessing the risk of actions taken at the aircraft repair site, which was implemented in the training version of the virtual reality (VR) simulation. It includes a number of factors and elements that form the simulation scenario, influencing the degree of its complexity and the assessment of the performance of each exercise. Various components of the algorithm are presented, which allow assessing the skills of students of aviation specialist courses. The criterion for the acceptability of the developed algorithm is the correct assessment of the student’s skills in the course of training.

“…It needs to be explained that, despite the improvement of FMEA reliance on decision-making methods, the opinions of the members of the FMEA team can be uncertain regarding the type of experience and base; therefore, the use of existing approaches to solve uncertainty problems, containing fuzzy theories, is presented to cover some of the traditional RPN deficiencies (Wang et al, 2016). Also, in terms of developing the risk assessment methods by the matrix approach, the most pragmatic matrix (qualitative) risk assessment methods, such as a 3 × 3 matrix (OHSAS), a 4 × 4 matrix (AS/NZS 4360), and a 5 × 5 matrix (MIL-STD-882B) was presented (Kovačević et al, 2019). Moreover, a study for emphasizing the importance of involving Multiple-Criteria Decision-Making (MCDM) methods was conducted which aims to select the optimal type of hotel for investment.…”

“…The assessment of risks based on likelihood and consequence (or severity) is a standard aspect of modern risk assessment, with the interaction between likelihood and consequence often expressed as a risk matrix. 12 A risk matrix provides a shorthand way of establishing the actions that should be taken in respect of a risk, and particularly whether an activity should be able to proceed. However, the validity of the risk matrix approach relies on an objective calibration of the risk levels in the matrix, and does not generally provide an estimate of the level of resources that should be committed to address an identified threat.…”

Quantifying the Cost of Drone-Related Threats in New Zealand

This article provides initial estimates of the most significant threats from drones in New Zealand. An economic approach is adopted with risks expressed as an expected annual cost, which is consistent with the adoption of a cost-benefit frame-work for policy development. It will be demonstrated that the expected annual cost of drone misuse are greater than that of a mass shooting, with the risks in the prison system alone exceeding the expected cost of a mass shooting. The expected annual cost of a terror attack exceeds that of the risks to the aviation industry. However current government proposals for registration of drones and licensing of pilots will do little to address the potential threats, which generally – though not exclusively – arise from individuals who have no intention of complying with the law. Indeed, it seems unlikely that the Ministry of Transport’s proposed policies will be effective in countering the most significant threats – those policies are likely to cost more than the risk that they might avert. Consequently there is a need to develop a strategy for countering the misuse of drones by those engaged in illegal activities.
