Lytvynenko O. Organizational and technological models of construction quality assurance in the conditions of digital transformation

The dissertation contains a new solution to the current scientific and applied problem of creating information and methodological tools to ensure the quality of construction and formalization of the apparatus for calculating the parameters of quality of construction works in digital transformation, aimed at ensuring the quality level provided by the project minimize deviations of quality parameters of construction processes through transformational functional-organizational and organizational-technological changes and clarifications in the process of operational construction management, reengineering of operational management and digital administration of construction projects, ensuring successful communications and reliable interaction between leading participants in construction which is a reasonable projected improvement in the quality of construction work. The results of the dissertation confirm the accepted hypothesis about the possibility of building quality management based on the application of new, based on the capabilities and benefits of digitalization, quality administration tools for construction processes, which should reduce the complexity and cost of construction and extend the life of individual buildings. and structures and their structural elements through quality management throughout the life cycle of the object, improving the technical and economic performance of construction projects and projects by combining and summarizing reliable operational information from the construction site on the quality of construction products, construction processes, material -technical resources during quality management. The basic contours and basic principles of forming a comprehensive quality system based on the formalization of the parameters of the processes of construction organization, which, in turn, determined the methodological basis and course of further research. A new system of forming the quality of construction of the facility, which is based on the format of "deviation management" based on the use of fuzzy logic and collection and analysis of quality information based on control charts and aiming to minimize deviations of qualitative parameters of the construction project. based on a combination of information and parametric base of construction participants and implemented throughout the project life cycle in the format of a single digital information model, partial or complete parametric base which can be used as a basis for modeling the quality system of similar objects or similar types of construction works or processes on other buildings or objects. The dissertation develops and implements a digital quality monitoring system based on the use of fuzzy logic methods to assess the impact on the overall quality of construction products of individual parameters of quality of construction processes, building materials, products and structures, quality control methods and other parameters. trends of previous periods based on operational information from the construction site. This approach is the theoretical basis for the construction of information organizational and technological models to ensure the quality of construction and adaptive tools as part of a single integrated system of building quality. The main practical result of the study is the organizational and technological models of quality management of construction of the object, which includes the system of administration of the quality of construction processes, products and contractors, as well as identifying quality assessment criteria. Based on the research results, a system of fuzzy equations for ensuring the quality of facade systems (in the Matlab environment) was created, and a methodological approach to adapting the proposed equations to other types of construction work was proposed.
