The authors propose an approach to assessing the possibility of stabilizing controlled impact on the ecological system, its climatic characteristics, within a limited space. Maintaining the necessary climatic parameters at an acceptable level ensures the stability of any ecosystem, the natural habitat of all living organisms, the preservation of biodiversity, including humans. The biggest potential threat is the rapid dynamics of global warming. Rising temperatures are the cause of extreme weather events, which directly affects environmental and food security. Given the urgency of the task, there is a need to study the controlled mechanism of influence on certain climatic factors in order to curb abnormal dynamics and bring the ecosystem into a state of stable equilibrium. The approach proposed by the authors is based on modeling the process of reducing the risk of crisis situations with abnormal fluctuations in ambient temperature. The mathematical model is represented by a system of ordinary differential equations, which is a consequence of the adaptation of Lagrange equations to oscillatory processes. The state of the studied climatic factor is matched by some random process, the amplitude of which depends on the values of the components of the control vectors and the function of external influence. The experimental parameter is ambient temperature. The problem was solved using statistical data for the Zhytomyr region (Ukraine). The main results of the simulation are to obtain a set of control vectors and functions of external influence, which will be taken into account in the information system for monitoring the environmental situation.

We have offered the investigations aimed at the design of eco-efficient technologies during oil and gas producing sites life cycle. The authors have conducted the analysis of conditions causing environmentally hazardous situations at oil and gas producing sites. We have established the necessity of quick maintenance of operation during emergencies that makes it possible to reduce material costs and environmental pollution. The increase of environmental safety in the process of winding up oil and gas wells emergencies that took place as a result of catching drilling string or some other pipe is crucial. We have analyzed different ways and various structural designs of the devices for pipe unscrewing from caught strings. We have established the ways of negative environmental impact reduction in the winding up emergencies at operating as well at stack oil and gas rigs. The recommendations regarding the structural design of the device are given. The device design is patented and the prototype model of the device is designed and manufactured. The device functions as the transformer of clockwise drilling string rotation into anticlockwise rotation of fishing tools. We have highlighted the positive effects after the implementation of the given device. We have noted the importance of innovative technologies design as well as the importance of forming adequate response skills during emergencies when wellsites are being constructed. The technical solutions and recommendations we have introduced make it possible to prevent negative environmental impact and reduce resource flows at different stages of wellsite life cycle.

The authors study the process of decision-making optimization in the control of the spacecraft onboard systems. To ensure the continuous operation of a remotely controlled complex technical system, it is necessary, on the basis of an analysis of the state of the onboard systems, to formulate control effects, the absence of which could lead to the system's failure to fulfill its tasks or system failure. In order to prevent such situations, an approach based on a simulation model is proposed, the use of which will reduce the risk of accidents in the onboard systems of the spacecraft. The proposed model is represented by factor space. The state of the onboard parameters of the spacecraft at different points in time is matched by the set of points that form the decision-making surface in this factor space. The basic stages of forming the optimal trajectory on the decision surface, which are approximated by numerical methods, are given and described. Using the actual values of the parameters obtained in a 15-minute data communication session from the board of the artificial satellite Earth "Ocean-1", a decision-making surface was constructed. The equation of the optimal trajectory on the created surface is obtained. The simulation results will be used to develop emergency management and control systems.
