The Impact

Risk assessment in large organizations with extensive operational domains has been a challenging issue. Employing an efficient method along with realistic pair comparisons, applying subjective inferences of organization experts, and purging the intrinsic ambiguity of inferences, are not reflected in current airlines' safety management. Traditional two-dimensional risk assessment for risk management of safety hazards, however, is no longer sufficient to comply with this complexity. A new model for risk management and a novel formula for risk index calculation, based on a fuzzy approach, are presented in this study. In this new model, unlike in the traditional approach, the latent aftermath of safety reports, especially those which affect the continuity of the business, is also taken into account. In this model, along with the definition of a new structure for risk management, risk analysis should be restructured. To that end, a two-dimensional classic risk formula was replaced with three-dimensional (nonlinear) exponential ones, considering “the impact on the business” as a source of risk and hazard. For measuring the safety risk using the Fuzzy hierarchical evaluation method, considering experts' opinions, three criteria in four different operational fields were developed. This method employs a Fuzzy ANP to help quantify judgments, make qualitative judgments in the traditional method, and weigh the priority of elements contributing to risk. Also, it provides a tool for top-level as well as expert level management to monitor safety more precisely, monitor the safety level within their departments or organizations, set quantitative safety goals and provide feedback for improvement as well as find the most critical areas with the least cost. In this study, an airline has been selected as a case study for the risk assessment of reports based on the new model.

UAVs performance is improved, in addition to GPS, they can find routes with artificial intelligence and various techniques, and can fly autonomously. The global UAV market was US$ 25.59 billion in 2018. It is estimated that the market will reach US$70.28 billion by 2029. The first three UAV manufacturers were DCL (USA), Parrot (France) and Yuneec (PRC) and are now being produced in many countries. Aircrafts are exposed to various risks: an aerodynamic stall due to inconsistent sensor readings and inadequate response, hitting a flock of geese or flying objects, pilot being unable to prevent the plane repeatedly nosediving despite following procedures. Therefore, procedures issued by aviation agency for aircraft type certification require an aircraft manufacturer (“applicant”) to demonstrate that its design complies with all applicable agency’s regulations and requirements. Safety risk management is a key component of a safety management system and involves fundamental activities such as identifying safety hazards, and assessing the risks and mitigation. Risk management is an integral component of safety management and involves some essential steps.Take into account any current mitigation measures and assess the seriousness in terms of the worst possible realistic scenario. The risk assessment considered five operational environments; remote, rural, suburban, urban, and congested. Reliability, availability, maintainability, and safety assessment are important study in the development of UAVs. This kind of study is mandatory to increase the reliability of the UAV, its availability, and to reduce repair and maintenance costs.

Safety risk assessment in dams is a traditional and modern approach to the engineering process of dams on safety systems so as to produce a design history that has a good overall record and integrity. With this approach for both old and new dams, this safety risk assessment aims to determine whether the risk the hazard can be tolerated or not, if it cannot be tolerated then there must be a solution for action to reduce the risk of danger so that the safety of the dam can be obtained. The existing risk assessment can be used as the basis for the construction of the dam to its maintenance, in this study discussed risk assessment safety on dams located in several countries such as in Asia, Europe and America. The methods implemented include the preparation of safety risks, risk analysis, risk evaluation and safety risk management. Based on research results The main risk factor that causes safety responsibilities is the Contractor's responsibility, namely the Non-technical project factor (40.54%), the 2nd rank is the Undecided Responsibility due to internal technical factors (35.13%), the 3rd rank is the technical project factor namely Contractor's Responsibility (10.8%), Rank 4 is external technical factor and external non-technical factor, the last risk factor is internal non-technical factor (2.7%) namely Joint Responsibility.

This paper addresses the role of human fatigue in workplace safety and risk management. It is well known that fatigue can increase the likelihood of workplace injuries, but the systematic application of this knowledge in safety and risk management is less well known. This paper presents a risk-based method for addressing fatigue in safety and risk management processes. The method incorporates elements of a data-driven fatigue risk management system (FRMS). Specific issues include potential data sources for the FRMS and practical applications within existing safety management systems. Special attention is paid to the fatigue risk assessment, which mirrors a common safety risk assessment and affords systematic control of fatigue-related human error.

The article considers the problems of application of aerospace technologies in the management of environmental safety of the planned activity with the help of integrated automated systems. The purpose of the article. The aim of the article is to determine the features of the application of aerospace technologies in the management of environmental safety of planned activities using integrated automated systems and the formation of a methodology for assessing environmental risk in the ecosystem. The scientific novelty is that the proposed methodology for assessing environmental risk in the ecosystem and provided scientific and practical recommendations for the use of space technologies for Earth observation to study the state of the environment in the management of environmental safety of planned activities Conclusions. The methodology of ecological risk assessment in the ecosystem is considered. The risk analysis scheme includes a wide range of interrelated problems and different stages: identification of risk factors, risk assessment, risk management. Recommendations for ecosystem risk assessment are provided. Features of risk management in the ecosystem are considered. The risk management strategy defined in the environmental decision-making support system may be based on the choice of the level of risk in the range from the minimum (which is considered to be quite small) to the maximum allowable. The article considers several strategies for environmental safety management: prevention of the causes of catastrophes up to the abandonment of products of hazardous industries, closure of emergency facilities; prevention of emergencies in cases where it is impossible to avert the causes of disasters (construction of protective structures, dams, the creation of an underground economy, early evacuation of the population, etc.); disaster mitigation, implementation of stabilization and compensation measures. The most suitable, from the point of view of the main goal of environmental safety management, is risk minimization, ie the implementation of the first and second strategies. However, in practice this is not always possible. A combination of all three types of strategies is most likely. Therefore, the selection of space survey materials is an important step in the classification for environmental monitoring. Procedures of thematic decoding and creation of digital maps of the area with the use of comic images are considered. When creating a digital map of ecological monitoring of regions, it is advisable to use the procedure of creating a vector layer of terrain in the ArcCatalog environment, and build a mosaic image using the software Erdas Imagine. Key words: aerospace technologies, ecological safety, ecological information, ecological problem, ecological threats, environment, process of making information ecological decisions, system of support of ecological information decisions, system of management of ecological safety, system approach, managerial decisions.
