The developed methods and models can be used to solve the current scientific and practical task of increasing the management efficiency and profitability of construction enterprises in conditions of insufficient information under the influence of technological, economic, political, social and other external factors, the consequences of which cannot be predicted. One of the methods that allow solving this problem is the diversification of the activities of construction enterprises. The relevance of the task of diversification for construction enterprises is based on several key factors. The first factor is the demand for the development of the construction industry in conditions of rapid economic growth in countries with favorable conditions. Rapid economic growth is manifested in an increase in the country's GDP, an improvement in the population's standard of living, an increase in employment, the development of infrastructure, an increase in the volume of trade and foreign investment, etc. The People's Republic of China is known for its impressive economic growth over the past decades. This achievement was possible due to the rapid pace of industrialization, an export-oriented approach to the economy, and the comprehensive implementation of reforms. Diversification can help businesses use their resources, such as human resources, equipment, and technology, more efficiently by expanding their applications in different markets or industries. Diversification can give a construction company a competitive advantage, providing it with a more flexible and adaptive business approach that will expand the range of services to meet the needs of different customers. However, the construction industry is known for its high vulnerability to economic fluctuations and changes in the market situation, economic situation, political turbulence and conflicts. That is why, in these conditions, several unresolved issues arise. More studies need to be conducted regarding including a separate diversification center in the company's organizational structure, whose activities aim to form, evaluate, and choose the company's diversification strategies. Also, in the case of horizontal integration, the influence of the choice of construction technologies and the choice of the values of the technical and economic parameters of construction on the choice of the diversification strategy of the construction enterprise has yet to be clarified. There needs to be sufficiently reliable methods of evaluating and selecting diversification strategies that would provide an opportunity to increase the profitability of construction companies. The creation of methods and models for forming, evaluating, and selecting diversification strategies for construction enterprises will increase their productivity and profitability and expand theoretical and practical developments in this direction. Therefore, this dissertation solves an important task, namely, the development of models, methods and information technology for choosing rational strategies for the diversification of construction companies, which is characterized by taking into account changes in the structure of organizational environments of companies and organically combines the entire range of activities of companies in conditions of uncertainty ( scientific component). Automating the evaluation and selection of diversification strategies is also solved. The developed methods and models are integrated into the relevant information technology (practical component). The object of the study is the processes related to the evaluation and decision-making regarding the choice of diversification strategies for construction companies in uncertain conditions. The subject of the research is the methods, models and information technology of managing the activities of construction companies in terms of forming, evaluating and choosing rational diversification strategies in conditions of uncertainty. Research methods. The research is based on knowledge presentation and processing methods, evaluation methods, monitoring of construction companies and their organizational structures, object-oriented programming, project management. The study aims to develop methods, models, and information technology for evaluating and choosing diversification strategies for construction companies to manage their activities in uncertain conditions. The scientific novelty of the obtained results: • for the first time, a model for choosing rational diversification strategies of construction companies is described based on an expert assessment of the technical and economic parameters of construction, which takes into account the most significant indicators and allows taking into account the advantages of participants in the construction process. • the method of evaluating diversification strategies of construction companies has been improved, which is distinguished by taking into account changes in the structure of organizational environments of companies, which is characteristic of conditions of uncertainty and allows to increase the efficiency of their management. • the method of forming diversification strategies has been improved, which takes into account the analysis of information about the activities of construction companies based on engineering and the concept of open sources, which is used to create a list of alternatives in the task of choosing rational strategies for the diversification of companies and allows expanding their management capabilities; • improved information technology for evaluating and choosing diversification strategies of construction companies in conditions of uncertainty, which is distinguished by taking into account the technical and economic parameters of construction and the advantages of participants in the construction process and allows expanding management capabilities and rationalizing the choice of diversification strategies of construction companies. • received further development of the conceptual presentation of the structural model of the organizational environment of construction companies, which takes into account the diversification of their activities and is distinguished by the fact that it organically combines the entire range of activities of project- oriented companies in conditions of uncertainty. The first chapter describes the peculiarities of the diversification of construction enterprises, the main concepts, types of diversification, and the possible effects of the diversification of activities. The relevance of the development of the construction industry and the diversification of the activities of construction companies are substantiated. The possible consequences after the diversification of the construction industry are characterized by conditions of uncertainty and risk: more effective use of human resources, equipment and technologies, risk reduction, intensification of post-war reconstruction (in Ukraine), an increase in the level of development of infrastructure, manufacturing and housing construction in countries with rapid economic growth (especially in the People's Republic of China). The well-known methods of multi-criteria decision-making are described, which motivate the application of decision-making strategies in the conditions of formation and evaluation regarding the diversification of the activities of the construction enterprise. It is indicated that since diversification strategies can have a significant number of evaluation criteria due to the presence of many stakeholders, financial needs, diversity and heterogeneity of the industry, the application of new or modification of known methods of multi-criteria decision- making can help solve the task of evaluating diversification strategies of construction enterprises. Since the task of assessing the diversification strategies of construction companies is complex and has many influencing factors, it is essential to develop information technology that would significantly simplify the work of the construction company's decision-maker or management team. In the second chapter, it is established that in the uncertain conditions in which construction companies operate, it is necessary to change the perception of the organizational environment of the construction company, which consists of the internal and external environment and task environment. These components of the same organizational environment were described with the caveat of the need to include a separate component corresponding to diversification tasks. Thus, because of the study, the conceptual presentation of the structural model of the organizational environment of construction companies, which takes into account the diversification of their activities and is distinguished by the fact that it organically combines the entire range of activities of companies in conditions of uncertainty, received further development. A formal presentation of construction technology and the task of choosing a construction technology is described. The choice of construction technology, in combination with the analysis of the competitive market and the analysis of technical and economic requirements for the task of diversification, makes it possible to thoroughly approach the formation of diversification strategies for the construction company. The concept of the formation of diversification strategies of construction companies is described, considering the principles of engineering, which takes into account six main stages from the formation of requirements for diversification activities to the evaluation of the results of implementing the diversification strategy in construction projects. A list of advantages from the formation of diversification strategies based on new principles is described: the ability to reflect complex diversification processes and management processes of construction companies in conditions of uncertainty, taking into account engineering; the ability to create, evaluate and implement diversification strategies and use a scientifically based selection of optimal diversification strategies that are aimed at increasing the profits of the construction company, increasing the credibility of the analysis of diversification data and the competitive market, using the concept of open data, etc. The third chapter describes the general task of the multi-criteria selection of diversification strategies for construction companies, which can be used in conditions of uncertainty when the external environment influences the company's activities: technological changes, political, economic, and other factors. The model for choosing rational diversification strategies of construction companies based on an expert assessment of construction's technical and economic parameters is described, which considers the most significant indicators and the advantages of participants in the construction process. These advantages and the features of diversification strategies are included in the indicators of the diversification center, which should be created in the construction company. The method of evaluating diversification strategies of construction companies has been improved, which is distinguished by considering changes in the structure of companies' organizational environments and allowing them to increase their management efficiency. This method is based on expert assessment and considers the opinions of all participants in the construction process: owners, developers, investors, general contractors, and designers. The method described for evaluating the diversification strategies of construction companies was verified using the example of a construction company in the People's Republic of China. The fourth chapter describes an improved information technology for evaluating and choosing diversification strategies of construction companies under conditions of uncertainty, which is distinguished by considering the technical and economic parameters of construction and the advantages of participants in the construction process and allows expansion management capabilities and rationalize the choice of diversification strategies of construction companies. The practical significance of the obtained results is that the developed methods, models and information technology for the formation, evaluation, and selection of diversification strategies of construction enterprises are an essential step in developing a theoretical and practical basis for ensuring sustainability and profitability of construction companies. The resulting tool is practically important for construction companies, holdings, and the construction industry. In the long term, using the developed methods and models will positively impact the development of the state's building industry. The main provisions and results of the research were implemented and applied in the activities of Yancheng Polytechnic College. The obtained results, theoretically and practically, serve as a basis for further scientific and applied research aimed at improving various aspects of the management of construction companies. Ensuring the sustainability of the development of construction companies and the organization of their diversification activities are the key signs of the sustainability of the development of the country's construction industry.
