Information and Analytical Basis for Assessing the Reliability of Construction Project Executors

Almost every project is an iterative process that includes refinement, revision of decisions, changes in architectural and structural solutions, as well as methods of manufacturing structures and building construction. Digital technologies in construction management also include virtual reality (VR) and augmented reality (AR). The use of VR and AR allows you to visualize construction projects before their physical implementation. Thus, an integrated solution that performs visual and graphical defragmentation of the life and operational and production cycle of a construction project using the principles and applied tools of digitalization, represented as a Fuzzy model, allows you to create or edit the model at any stage, is the closest to reality and leads to a reduction in the time between the design and construction phases of the life of a construction project. Since project management is closely related to decision-making processes, decisions are made under conditions of certainty (the outcome of the decision is known), risk (an event may occur and a certain estimate can be made), uncertainty (probability). and the consequences of the event cannot be predicted). A method for managing a construction project based on fuzzy logic has been developed, which makes it possible to assess both the intermediate state of project implementation by its individual parameters and to predict the project outcome in a changing environment. The construction of a fuzzy model of a project management system is based on a formal representation of the object's characteristics in terms of linguistic variables. In the control system, the input and output variables of the system are considered as linguistic variables. The purpose of management is to determine the values of control variables (inputs), the implementation of which ensures the desired behavior or desired state of the project as a management object. Real-time project analytics is the main source of information for decision-making. It allows to productively structure the task of assessing the reliability of construction contractors and formulate its regulations for a particular construction company with unique operational and production specifics.
