Introduction. At the current stage of implementation of the Strategy for development of the construction industry and housing and communal services of the Russian Federation for the period till 2030 there is a need for management of unique innovation projects on creation of hi-tech construction products and products for which there is no historical retrospective and sufficient experience in management of such projects: development and creation of composite materials, metal powder for the additive manufacturing, self-healing concrete, etc. Therefore, the problem of developing a mathematical model forthe creation of hi-tech building products is relevant.
Materials and methods. Working out the model, the methods of Markov and semi-Markov systems modelling and methods of programmed planning that have proven to be good at modelling the stages of the life cycle when creating high-tech and unique samples of special purpose machinery were applied.
Results. A model of creation of hi-tech building products, which allows to model and manage the stages of the product life cycle, has been developed. The results of numerical modelling are given. The results of the modelling have shownthe possibility of effective management of the stages of the life cycle of high-tech products. The developed model is a part of scientific and methodical apparatus for end-to-end modelling of basic stages of life cycle of high-tech building production. In this case, depending on the specific problem to be solved, the modelling of individual stages of the life cycle can be carried out with different levels of detail using those or other models of life cycle stages. For certain types of created products, some of the life cycle stages may be excluded from the general model or, on the contrary, added to the general model. The model developed in the article can serve as a means of obtaining additional input data to be used for information modelling with the help of BIM technologies.
Conclusions. The developed model adequately enough describes real processes of product development and creation. The model is not demanding for quality and completeness of input data.
