The innovative content of the components, stages, and results of the construction and implementation of the toolset, which provides a formalized assessment and choice of a rational scenario for reengineering implementation at a modern enterprise in the form of a target project, was displayed. The need for research is caused by the fact that the existing approaches to reengineering business processes in an application for construction enterprises require significant adjustments. The reengineering of a construction enterprise as a target project should be coordinated with the projects and works executed by a construction enterprise. The proposed analytical support makes it possible to determine for each of the construction enterprises an alternative to reengineering adapted for its needs. Modules as part of the proposed analytical support implement a single algorithm of unambiguously formalized substantiation of the construction enterprise renovation project – through a developer reengineering project. This toolset allows rationalizing and adjusting decisions on the coordination of determinative characteristics of the above project – the essence of changes, their duration, estimated cost, investment stages. The presented study provides a clearly formalized management technology for evaluating and selecting reengineering options, determining in advance the future benefits of reengineering transformations, namely, functional-technological, technological, technical, managerial, and economic changes. The created analytical support makes it possible to perform successful administrative support of a reengineering project. Its implementation will ensure an irreversible qualitative "jump" in the trajectory of the life cycle of an enterprise and expected strategic priorities.

The purpose of this research is to study the communication network among the participants in a construction project. The proposed approach contains the solving of the following tasks: identification of the key factors that affect the communication quality; calculation of the “communication quality” indicator between each pair of participants using fuzzy logic; and evaluation of the key measures of centrality using the tools of a Social Network Analysis. Solving the set tasks can help break the problem of the low level of efficiency of construction project deliveries. This study was conducted when the design stage was already complete and the construction project had 17 participants. We used the following factors influencing communication quality: timeliness, understanding, bidirectionality, use of IT tools in communication acts and adequacy. The use of fuzzy logic tools can minimise the subjectivity of the qualitative data obtained from the questionnaires. The analysis of five centrality measures showed that “Project manager”, “Chief engineer”, “Construction site manager”, “Construction works manager” and “Architect” had the greatest values in comparison with other network participants. On the one hand, this organisational structure of communication can be considered correct because the main information flows through the project managers, who make the decisions. On the other hand, this indicates a significant dependence of the construction project on these participants and, in the event of certain risk events, may lead to a decrease in the efficiency of its implementation. The methods presented in this article can be used in project management to analyse a real communication network.

World experience shows that the realities of modern times create conditions for permanent transformations of operating systems and the formation of updated models of organizational structures of construction enterprises-stakeholders, aimed at more effective use of the economic and organizational-technological potential of the business entity, expanding the range of opportunities for economic and managerial growth , form prerequisites for the development of business structures and provide an opportunity to introduce innovative forms of knowledge management in enterprise administration. The relevance of the issues of cognitive research is determined by the features of the development of modern society. A characteristic feature of today is the presence of unified information technologies (IT) in almost all spheres of life. IT enables the sharing of information on a global scale, the collection and integration of vast data sets from dispersed and diverse sources. Big data sets collected in this way are used for forecasting and generating new knowledge. Contrary to the boundaries of disciplinary affiliation and commitment to different scientific schools, scientists are united by the paradigm, theory and methodology of cognitive science. At the basis of modern scientific research, the subject of production, with its knowledge, abilities and skills, is emerging. The latest scientific studies of cognitive mechanisms were mainly focused on the analysis of processes, models and practices of knowledge management of an individual organization, and only a small number of their studies were aimed at evaluating and optimizing processes related to the integration of knowledge in the project. The process of knowledge integration should ensure the dynamic potential of organizations – the ability to integrate internal and external knowledge to respond to environmental changes. The article analyzes and classifies the components of knowledge management systems in construction: an information technology system, in which special attention is paid to information technologies (IT); an organizational system that focuses on what the project's organizational structure and various processes and procedures should be; a human system that is focused on the management of human resources through digitalization and means of communication through the "information explosion", which is due to the transformation of the operating systems of enterprises in the dimensions of the "complexity of the world" indicators: SPOD-world, VUCA-world and BANI-world. Світовий досвід свідчить, що реалії сучасності створюють умови для постійних трансформацій операційних систем та формування оновлених моделей організаційних структур підприємств-стейкхолдерів будівництва, що мають на меті більш ефективне використання економічного й організаційно-технологічного потенціалу суб’єкта господарювання, розширюють спектр можливостей економіко-управлінського зростання, формують передумови для розвитку бізнес-структур та надають можливість впровадити інноваційні форми управління знаннями в адмініструванні підприємством. Актуальність проблематики когнітивних досліджень визначається особливостями розвитку сучасного суспільства. Характерною особливістю сьогодення є наявність єдиних інформаційних технологій (ІТ) практично у всіх сферах життя. ІТ дають змогу обмінюватися інформацією в глобальних вимірах, збирати величезні набори даних та інтегрувати їх із розосереджених та різноманітних джерел. Зібрані в такий спосіб набори великих даних використовуються для прогнозування та генерування нових знань. Незважаючи на межі дисциплінарної приналежності та прихильності до різних наукових шкіл, вчених об’єднує парадигма, теорія і методологія когнітивної науки. В основі сучасних наукових досліджень повстає суб’єкт виробництва зі своїми знаннями, вміннями та навичками. Останні наукові дослідження когнітивних механізмів здебільшого були сфокусовані на аналізі процесів, моделей та практик з управління знаннями окремої організації, і лише незначна кількість досліджень була спрямована на оцінку й оптимізацію процесів, пов’язаних із інтеграцією знань у проєкті. Процес інтеграції знань має забезпечувати динамічний потенціал організацій – здатність інтегрувати внутрішні і зовнішні знання для реагування на зміни навколишнього середовища. У статті проаналізовано і класифіковано складові системи...
