Digitalization of technological and design decisions making processes in modern construction

The results of the study can expand the implementation field of the “decisions tree” method. This method can be used in the design decision making processes and technological equipment options when choosing construction equipment for the production of earthwork. The study was carried out on the example of the “Voznesensky” Architectural Ensemble? in Tyumen, hereinafter “Voznesensky AE”. Following goals were achieved: options for a traditional approach to determining the need for construction equipment were considered; models and methods of making managerial decisions were analyzed; the method of “decisions tree” was studied, advantages and disadvantages were identified. The “decisions tree” method ia successfully applied in a digital experiment and recommended for real implementation in the development of an algorithm for making design decisions and when choosing options for mechanizing the production of excavation work using the Deductor Academic Studio program at the construction of a real facility. Currently, there are no cases of direct application of the «decision tree» method in the management of projects in the Russian construction industry. There are no published research results to introduce the «decision tree» method in the processes of design and production decisions
