Variance Analysis in Assessing the Parameters of the Virtual Passport of Capital Construction Objects

Statement of the problem. An analysis and generalization of experimental data using methods of one-factor and two-factor analysis of variance is performed. The purpose of the study is to establish the defining relationships between factor variables and their quantitative analogues presented in the form of «responses» as well as to demonstrate the process of statistical changes in information parameters when using various methods of analysis of variance. Results.Information is summarized on the results of mathematical modeling of the parameters of information models that have different classifications and distinctive features depending on the types of documents used on them to regulate the processes of building information models. Null hypotheses are proposed, their refutation and proof are carried out using a statistical sample of experimental data obtained as a result of projects based on building information modeling technology. To conduct a visual analysis, tabular calculation results and graphical presentation of data in the form of scatter diagrams were used. Conclusions. It has been suggested that it is necessary to introduce a virtual passport of a capital construction project at the earliest stages of the project in order to reduce the risk of data loss in the process of changing the life cycle of the facility. It is proposed to reduce the overall project error by introducing a virtual passport and a project implementation plan into the interaction process in order to ensure consistency of data and information components.
