“…As it is imperative that terrorist risks and terrorist mechanisms of triggering emergencies be included into the framework of traditional risk assessment, the existing models and methods for analysis of accidents at CES should be modified, and new ones have to be developed in order to take into account specific properties of emergency initiation by terrorist impacts which can be targeted at the most vulnerable facilities of critical infrastructures. Most of the components of complex engineering systems were however constructed in conformity with national and international regulations and norms for design, construction, and maintenance without direct consideration of terrorist threats [17,18]. In this context, two major securityrelated problems arise:…”

The chapter will present the classification of the types of modern terrorism and describe scenarios and probabilistic models of ordinary, technological, and the so-called intelligent terrorism that are distinguished by their triggering events, propagation modes, damaging factors, probabilities, and consequences. A comparative assessment of these three types of terrorism is presented. Dynamic three-sided models allow assessing the situation from standpoints of terrorists and law enforcement agencies, the administration of the complex engineering system, and analyzing actions and counteractions of various sides involved. A new comprehensive approach to ensuring complex engineering system security is described. This approach is focused not only on the development of protection barriers and safeguards against predetermined list of design-basis scenarios of terrorist attacks but also on increasing the system's resilience toward beyond design-basis attack scenarios.

The combustion of flammable substances in an open area negatively affects the environment and environmental safety. Emissions of harmful substances, including carbon dioxide and nitrogen oxides, pollute the atmosphere, threatening air quality and contributing to the greenhouse effect. Combustion of flammable liquids also entails contamination of soil and water resources, with a negative impact on the natural environment. Fires and accidents are associated with threats to the environment and society. Studies of the dynamics of the combustion temperature of flammable liquids have identified three main stages: flame propagation, combustion during evaporation of the liquid, and combustion during boiling of the liquid. The experimental data obtained have the potential for environmental assessment and improvement of models that predict emissions parameters and their impact on natural ecosystems, and calculations of heat flows that have a detrimental effect on the environment. These data can also be used to estimate the heat flux generated by the combustion of hydrocarbons in open air, a key parameter for environmental impact assessment. Research has made significant contributions to the field of environmental safety, helping to reduce risks to ecosystems and reduce negative impacts on the environment.

Introduction. The need to increase the level of comprehensive safety, reduce accident and injury rates, minimize the risk of failures, accidents and catastrophes determines the relevance of research on the relationship of elements of the "human–machine–environment" (H–M–E) system during open-pit mining. One of the most effective mechanisms for studying the functional characteristics of the H–M–E system of a coal mine is to conduct simulation modeling in order to identify problematic situations that trigger accidents with catastrophic consequences and injury to personnel. Simulation modeling of a technological process involves constructing a model of a real system and setting up computational experiments to describe the behavior of the system and evaluate various strategies that ensure its functioning. The aim of the research was to adapt simulation modeling technologies to solve the problem of complex safety during open-pit mining. Within the framework of the study, the task was to determine the elements that made the greatest contribution to the implementation of risks in the H–M–E system during stripping operations at a coal mine. The simulated subsystems were "human", "machine", "environment", and "weather conditions". Materials and Methods. Stripping process was considered in the ARIS eEPC (extended Event Driven Process Chain) methodology as a business process linking a set of subprocesses and/or business operations. To build a simulation model in the AnyLogic software environment, the business process of stripping works in ARIS eEPC notation was described by a graph representing a structure consisting of objects and connections between them. This approach allowed us to structure the sequence of events and operations and determine alternative outcomes that arose during stripping operations. Results. As part of the research, a method was developed for translating the formal model of the stripping business process in ARIS eEPC notation into a combined simulation model of AnyLogic. Based on the developed method, a series of machine experiments was carried out. The elements influencing the realization of the risk of accidents in the H–M–E system of a coal mine were determined. Discussion and Conclusion. For the first time in the domestic practice of research of the H–M–E system, simulation modeling technologies have received an application for the analysis of complex safety indicators during open-pit mining. According to the simulation experiment results, it was found that the main influence on the decrease in the reliability of the "machine" subsystem was exerted by the human factor, which, together with the psychophysiological properties of a person, enhanced the development of the domino effect when implementing various types of risks. The presented results and experimental approbation of simulation modeling technology can have advanced use in the analysis of complex technical systems safety, taking into account the influence of human and man-made factors.
