Purpose. Justification of the appropriateness of use in terms of efficiency for a construction company, the process of integrating quality management and risk management. Determination of the principles of applying an integrative management model, modules for managing the quality of construction in conditions of risks based on a dynamic system. Methodology. Analysis and generalization of scientific research, practical approaches to quality management and risk management of construction projects, the use of the integration method and the method of identification of QM and RM processes, which makes it possible to substantiate the possibility of developing an integrated approach and determine the principles of applying an integrated quality management model in the face of risks. Results. The study substantiated the feasibility of using an integrative model of risk and quality management in construction, which allows the QM and RM processes to be aligned with the project efficiency criteria, and makes it possible to eliminate contradictions between the quality requirements for the construction object and the level of acceptable risks, and also aligns them with the efficiency requirements for developer. Originality. The principles of quality and risk management are determined, which are prerequisites for the integration of QM and RM processes; modules and levels of implementation of an integrated model of quality management in a risk environment, taking into account the requirements of project efficiency. Practical value. The use of an integrated approach aimed at combining quality management modules for projects and risks in the construction industry will allow to level all the contradictions of these processes in practical implementation, to harmonize with the efficiency requirements for projects and balance the costs of ensuring the planned quality level, provided that the acceptable level of risks is observed.

The article is of a generalizing nature; the authors investigate the problem associated with architectural design in the historical environment. The newly built civilian objects are considered as examples of the organic interaction between “old” and “new” in European cities. The authors’ positions of domestic and foreign professionals regarding the development of the potential of the historical centres of modern cities are considered. In connection with the dynamics of urban growth in the XXI century, the problem of renewal and development of historically established centers arises. Development as a modernization of the historical environment assumes a high-quality level of integration of relevant functions in the unique conditions of authentic urban structures. The cultural aspect of the problem is to solve the main problem of the historical environment -the preservation and protection of the valuable architectural and urban planning heritage. The authors highlight the need for an integrated approach to theproblem and formulation of a development strategy. The experience of Odessa shows the negative results of delay in such matters. Urban space as a living organism presupposes a progressive process of regeneration of both the urban structure and the “tissue” of the city, filling the space and being subordinated to the structure. A scientific approach presupposes discussion, variability and flexibility concerning the protection and development of the historical environment. However, taking into account the whole complex of economic, administrative, and cultural conditions, we can say about two main approaches in relation to the historical architectural environment in Ukraine. One is based on a conservative approach and denies the objects of modern architecture in the historical environment. This approach assumes that a historically formed urban planning formation is an integral urban planning phenomenon and only allows the construction of new objects in historical styles, allows the priority task of restoration and reconstruction of existing objects. Another approach is based on a dialectical approach and allows the introduction into the historical tissue of the city of new objects that meet all progressive achievements of engineering and technology, have modern and current features of the style (stylistic direction). At the same time, an important aspect is the novelty and high aesthetic level of architecture, due to the requirements of modern society. The logic of this approach comes from the very essence ofarchitecture, placed in the classic triad of benefit, strength and beauty. The most important factor that determines the value of the historical core of the city, in particular, the historical centre of Odessa, is the integrity of the historical structure, the interaction of all elements of the architectural complex, and a balanced urban infrastructure. At the same time, the architectural complex consists of objects of different value categories. Some are historical and architectural monuments of the universal, state and local importance. Others are authentic objects of “back-ground” development that contribute to the integrity of the city’s historical tissue. This is the picture that shows a historical accuracy. According to the authors, the scale for determining the objective value of each architectural object in this case is of a relative nature and, to a large extent, in our time is not the primary task of preserving the architectural heritage. The task of an integrated approach to the problem and elaboration of a preservation strategy is a priority task. In recent years, intensive construction has taken place on local fragments of the historical part of the city, which leads to the final destruction of the historical city. In many cases, modern civil engineering works are monotonous and have doubtful cultural qualities, and at the technical level they exacerbate the situation of collapse at the infrastructural level. There is an international, in particular, European experience in solving the problem of the conflict between new and historical in the cities of Germany, Poland, Spain, etc. The destructive cataclysms of the XX century caused great losses to the architectural heritage. The world community has developed norms and rules that allow for a huge number of implementation options in the context of regional features. The problem of a new construction in the historical environment today is not about the question of whether the object is stylized or modernized. The problem is to determine the principles of interaction of the historical environment with new structures, in the degree of “civility” of a new architecture, the ability of the “new” to further develop the potential of urban space.

Modern radio electronic equipment (REE) in various areas of economic activity performs increasingly complex tasks at sites with increased levels of responsibility. This circumstance increases the dependence of the operation of the REE on the uninterrupted power supply and its quality level, as well as on the level of fault tolerance of an important auxiliary part of the REE - power supply system (PSS), which significantly affects the ability of the REE to perform its tasks. The results of the analysis of existing and search for promising ways to ensure a given level of reliability of REE associated with its power supply problems show the need for an integrated approach to choosing the most effective option. It consists in the cumulative implementation of the process indicated by the newly introduced term «reliability of the power supply chain (PSC) of the REE», combining the continuity of supplying REE with electricity of the established level of quality and trouble-free operation of the PSS performing the conversion of the initial electricity to the form and the values of its parameters acceptable for the power supply of the functional units REE. Ways to improve the reliability of the PSC of the REE of ground stationary objects are considered for two of its characteristic types - a computer system (CS) and a telecommunication system (TS) with a single-phase voltage of 220V; 50Hz and the value of power consumption to 3-5kW. In terms of increasing the continuity of electricity supply, the feature of the proposed solutions is the achievement of the set goal by additional use of existing resources of the facilities of the REE installation. In some cases, their limited increase is also envisaged. In order to increase the fault tolerance, the PSS REA suggests: in the centralized part of the PSS - the application of the trunk-modular architecture, the choice of the effective structure, and also the adaptive methods and algorithms for management and redundancy, in the distributed part of the PSS - optimization of the structure and minimization of the number of constituent parts.
