“…There are multiple articles on methods of risk assessment, and they are widely described e.g., by Sun et al [4], Ting et al [5], and Vrabel et al [6]. The methods are focused mostly on risk estimation for particular problems (e.g., disease [7,8], cancer [9], earthquakes [10], floods [11]) or calculation of risk with the use of various techniques, e.g., Bayesian networks [12,13], attack trees [14], or the Dempster-Shafer theory of belief functions [4].…”

This article presents a new method of risk propagation among associated elements. On the basis of coloured Petri nets, a new class called propagation nets is defined. This class provides a formal model of a risk propagation. The proposed method allows for model relations between nodes forming the network structure. Additionally, it takes into account the bidirectional relations between components as well as relations between isomorphic, symmetrical components in various branches of the network. This method is agnostic in terms of use in various systems and it can be adapted to the propagation model of any systems' characteristics; however, it is intentionally proposed to assess the risk of critical infrastructures. In this paper, as a proof of concept example, we show the formal model of risk propagation proposed within the project Cyberspace Security Threats Evaluation System of the Republic of Poland. In the article, the idea of the method is presented as well as its use case for evaluation of risk for cyber threats. With the adaptation of Petri nets, it is possible to evaluate the risk for the particular node and assess the impact of this risk for all related nodes including hierarchic relations of components as well as isomorphism of elements.

Safety in automated workplaces is the most important feature of any machine, equipment and system as a whole in a modern and advanced society, where some part of it performs mechanical movement. The task is a set of comprehensive measures to prevent contact / collision of the device (robot, conveyor etc.) during this movement with any part of human operator. In addition, behaviour of modern automated workplaces is not always predictable, since movement (performed inside the automated cell) are usually controlled by a control program whose structure is only known to the manufacturer's programmer. These reasons pointed to the advanced functions use that is available in such equipment as light curtains.

“…2016). The infrastructure of developing countries is highly vulnerable and also highly interconnected (Vrabel et al 2015;Smol et al 2020) so risk assessment and management plays a very crucial role in managing resources. However, for a risk assessment to be valuable, it needs to be based on a strong preliminary examination that is generally called baseline study.…”

At national and global level, industrial revolution, urbanization and increasing trend of population not only increase our standard of living but also result in greater quantities of waste generated. Waste management and its proper disposal in landfills/open dumps are one of the major environmental issues that pose hazards and risks to the environment and human health. Landfill/ dumping sites are harmful for the environment along with all three principal spheres, i.e., hydrosphere, lithosphere and atmosphere (Szymanski et al. 2016;Butt et al. 2019; Jagod, 2018;Mahmood et al 2020). However, despite this fact and the faith in sustainability, landfill is the least preferred option. It is still a typically most applicable waste management option, not just in Pakistan but around the globe in developed or developing countries because of its simplicity and quick waste disposal.However, in order to ensure that landfills meet environmental standards, a detailed environmental risk assessment exercise is required. In some countries, it is legislative requirement, as in the UK (Regulation 15 of Waste management regulation). Developing countries also have legislation regarding environment and waste management. Environment was considered as a provincial subject in constitution of Pakistan in 2012. According to Policy and Regulation on SWM Pakistan 2010, it is reported that there are five stages in the process of establishing solid waste and landfill facility and the following aspects must be considered at each stage: 1. The need for having disposal facility 2. Appropriate site selection for solid waste disposal 3. Installing, commissioning, and operating solid waste disposal and landfill facility 4. Monitoring, evaluating, and reporting of solid waste disposal and landfill facility 5. Cessation of landfill facility. Establishment guidelines organized the rules and regulations viz, Pakistan Environment Protection Act (PEPA) 1997, Guidelines to prepare and review National Environmental Quality Standards (NEQS), Policy and Regulation on SWM Pakistan, 2010).Risk assessment (RA) is an essential part of risk management such as in financial risk management, credit risk management, engineering risk management, and other aspects; it plays a significant decision-support role for risk managers to adopt reasonable risk prevention measures and strategies (Mahmood et al., 2015a;Mahmood et al., 2014b;
