Problem Statement and Purpose. Approaches, principles and methods of research of anthropogenic landscapes, in particular landscape-technical systems, are considered in detail in the works of many scientists. However, less attention is paid to the study of water management landscape technical systems. This necessitates more specific approaches, principles and methods that would allow to fully reveal the essence of these systems. Water management landscape-technical system is a complex system that combinesnatural, technical and information blocks that interact with each other. Therefore, researching these systems, in addition to traditional and specific, it is necessary to use at the integrated level the principles and methods of various natural sciences. Data & Methods. In the process of analysis and disclosure of approaches, principles and methods of research of water management landscape system, the following methods were used: structural and logical generalization (used to identify traditional methods in the study of the system), abstraction (selection of specific methods to reveal the essence of the system), system analysis (establishment of integration links between traditional and specific methods of scientific cognition), generalization (made it possible on the basis of the obtained data on methods of scientific cognition to develop a scheme for studying the water landscape system of the Trubizh river basin). Results. It is noted that the study of water management landscape technical system is impossible without the use of a systematic approach, which is traditional in all theoretical studies. Approaches that help to reveal the essence of the water management landscape and technical system (historical, basinal, system, paragenetic, constructive, cartographic and geoinformational) are identified and analyzed. The cartographic approach is singled out, which is one of the main ones in the study of water management landscape technical systems. There is a particular emphasis on the geoinformational approach, as the development of GIS projects is one of the most promising and modern trends in the study of not only water management landscape and technical systems, but also anthropogenic landscape science in general. The essence of specific principles and research methods is revealed, as they help to understand the peculiarities of the water management landscape and technical system. Three basic principles (historicism, natural anthropogenic compatibility and advanced study of previous natural and anthropogenic landscapes) were considered, on their basis seven methods of scientific research were identified and analyzed. The author emphasizes that, in addition to the main approaches, principles and methods, it is expedient to use methods from other sectoral sciences in the water management landscape and technical system study (geology, geomorphology, soil science, hydrology, zoology, botany etc.). A generalized study scheme of the water management landscape and technical system has been proposed, using the Trubizh River as an example.

The article analyzes the problem of dynamics and multidimensionality of landscapes on the example of landscape and technical systems. The object of the study is a landscape and technical systems, which are characterized by significant dynamics and multidimensionality of the structure. The basis for the publication of the article was the materials of long-term field observations conducted in the framework of research of the Vinnytsia school of anthropogenic landscape science under the direction of H. I. Denysyk. The authors’ contribution is to analyze the dynamics and multidimensionality of the structure and development of the valley-river landscape and technical systems of the Right Bank Ukraine, which lasted during 2007-2019. Knowledge of the dynamics of landscape and technical systems allows one to better understand the specifics of the transformation of the modern landscape sphere and to calculate possible negative trends. It is noted that the dynamics of landscape and technical systems are functional, spatial, and structural transformations, which are manifested in all components to the critical moment of transformation of a block system into a geocomponent one. Four types of dynamics are considered. Chronological dynamics characterize the spatial changes in the boundaries of the landscape and technical system. Structural dynamics involves a change in the morphological structure of the landscape and technical system and the relationships between its blocks. Temporal dynamics unites all changes in the landscape and technical system related to time. Directed dynamics presupposes stable, unilaterally directed transformations of the landscape and technical system with multiple changes of its state and structure. It is noted that each system has its own distinctive feature – multidimensionality, that is, the functioning within it of a number of separate and simultaneously interconnected paradynamic systems. The internal block system is limited by the landscape technosphere of the planet, which combines modern soils, man-made cover, and the air layer. The internal structural-morphological system considers the landscape and the technical system as a clearly defined gradation of taxa. The internal inter-block system provides interconnection in the landscape and technical system at the level of three blocks (managerial, natural and technical). The external complex system expresses the interaction of the landscape and technical system with other landscape complexes. Through the external air system, there is an entry into the landscape and technical system and the reverse radiation of solar radiation and interaction with remote landscape complexes due to the transfer of different types of air masses. In the underlying lithogenic system, the interaction of the landscape and technical system with the lithogenic base, which is represented by the earth’s crust and the upper mantle, is manifested. It is determined that the knowledge of the problems of dynamics and multidimensionality of landscape and technical systems becomes the central problem of engineering landscape science. The development of theoretical aspects of the functioning of landscape and technical systems is of great practical importance. Understanding the specifics of the structure and development of a particular landscape-technical system will increase its economic efficiency and minimize the negative impact on adjacent landscapes. Therefore, in the future, it is necessary to emphasize the research of modern geographers on the problems of multidimensionality and dynamics of different classes of anthropogenic landscapes.

The article is devoted to the work of the Russian revolutionary, writer and Marxist theorist V. I. Zasulich. The subject of consideration is the historical and philosophical views of the thinker, which are analyzed on the basis of her study devoted to the work of J.-J. Rousseau – “Jean-Jacques Rousseau. The experience of characteristics of his social ideas”, which previously remained almost without the attention of researchers. The purpose of the work is to analyze the basic principles of the approach of V. I. Zasulich to the study of philosophical thought: the desire to recreate the historical situation and the mental situation, the focus on the selection of socio-political and ideological determinants of the views of a particular thinker, the selection of unique and innovative thoughts compared to contemporaries and predecessors, the influence of the thinker on contemporaries and descendants. The research methodology is the system analysis, and reconstruction of the works by V. I. Zasulich on the problems of research. The work of V. I. Zasulich is a full-fledged scientific research: it analyzes the works of the thinker, refers to other researchers of his work. It identifies the determinants of the direction of his works, the thinker’s innovation and contribution to philosophy, as well as his influence on the further development of spiritual life, that is, adheres to the Marxist methodology of historical and philosophical research (and largely forms this methodology for Russian scientists).

Abstract At present, elements of probabilistic safety and risk assessment have been introduced into the design and analysis of complex technical systems, one of the main disadvantages of which is the difficulty due to the selection of initial data in the form of probabilities of initiating events. As a consequence, the use of known methodologies for quantifying risk can lead to either underestimation of threats or unreasonably high security costs. On the example of an enterprise for the storage and processing of vegetable agricultural products, an approach was considered for assessing the risk of a technical system based on the probabilistic model “exposure-susceptibility”.

Authors explore issue of applicability of the methodology of building diagnostic software using network formal models in the functional testing of electronic equipment as part of complex technical systems. Using methods of system analysis allows to perform a decomposition of interdependent subsystems and to reveal basic acts of interaction between the control‑verification equipment and the object of diagnosis. Mathematical apparatus of Petri nets should be employed for the formalized description of such acts and determined the cause‑and‑effect relations in the diagnosed complex system`s processes. Network models properties studying (such as safety and accomplishment of the final positions) allows us to move to the test object`s algorithm`s developing. The article presents an approach of a formalized description for basic acts of interaction between the diagnosis system and the object.

Cheap does not imply cost-effective -- this is rule number one of zeitgeisty system design. The initial investment accounts only for a small portion of the lifecycle costs of a technical system. In fluid systems, about ninety percent of the total costs are caused by other factors like power consumption and maintenance. With modern optimization methods, it is already possible to plan an optimal technical system considering multiple objectives. In this paper, we focus on an often neglected contribution to the lifecycle costs: downtime costs due to spontaneous failures. Consequently, availability becomes an issue.

The main disadvantages of the existing methods of managing the current state of technical systems are revealed. A non-standard approach is proposed for managing the functionality of the system in emergency situations. The character of the dynamics of the recovery processes of the technical system is determined as its state approaches the emergency one on the basis of the recommendations of the theory of self-organized criticality (SOC). The physical criteria for assessing the current state of the technical system are revealed. The rationale for using the physical indicator of the functional destabilization of the system is given. The signs of the pre-emergency state of the technical system are considered. A grapho-analytical model for the development of an emergency situation has been developed. The fact of the inevitable increase in the entropy of the system upon its transition to an emergency state is established. Structuring of the system development process in an emergency situation is carried out in three stages. The methodology for estimating the pre-emergency state of complex open systems is presented. The advantages of the proposed approach to managing the state of technical systems in comparison with traditional ones are established.
