Based on the system analysis using IDF0 diagrams, functional models of existing technical systems for cleaning used oil have been constructed. The influence of the parameters of the technological process on the time of its flow and the degree of purification of the used oil are described. After studying the influence of the parameters of the technological process of cleaning used oil and analyzing the existing automated technical oil purification systems, the necessity of developing a new automated technical system for cleaning the waste oil is substantiated, in which the parameters of the process that have not been considered previously will be monitored.

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 analysis of the modern approach to the choice of technological processes of production of heavy concrete products and its weaknesses were shown. It is proved that the technological process as an object is a weekly structured system due to the large degree of uncertainty associated with the human factor. It is established that development of new assortment approach to the choice of technological process of the production of construction materials differing in alleged accounting of functional purpose and service conditions of building constructions in a real estate object can be one version of the solution of this problem. The concept of the choice of optimum technological processes of production of construction materials distinctive in alleged accounting of functional purpose and service conditions of building constructions of real estate objects is developed. The technologies of mathematical statement and the solution of problems of optimization of technological processes of production of the range of construction materials differing in increase in degree of structure of system liaisons with external subsystems on the basis of standard mechanisms of the subject focused accounting of functional purpose and service conditions of building constructions and also standard algorithms of search of optimal solutions for defined the range are developed. Assessment of efficiency of assortment approach to a problem of optimization of technological processes of production of the range of construction materials including comparison of the characteristics of material received as a result of use of modern approach, assortment approach in the set parameters of management and assortment approach with expansion of a set of essential alternatives of technological process of production of the range of construction materials is executed. This assessment has shown that more perspective alternatives on qualitative content of characteristics of material are outside area of normative requirements and need justification.

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.
