Introduction. In organizational and technological documents the issues of transport provision with material resources of construction objects are considered without sufficient substantiation. In the article the task of supply volume planning is coordinated with the internal capabilities of the construction organization and with external conditions, and then formulated in the form of a mathematical model of linear programming. The principles of planning are defined, external and internal restrictions on the choice of the plan are formulated. The planning model developed by the author will allow to increase the organizational level of material flows management, will provide continuity and uniformity of production of works, consumption of materials, products and designs. Purpose of the article is to develop a effective model for the management of material flows in construction. Method (methodology). In the process of developing and substantiating the results of the study, the following research methods were actively used: analysis, synthesis, modeling, logical, systematic approach, methods of deduction and induction, as well as observation, measurement, comparison, experiment. Results. The main factors of ensuring the efficiency of material flow management are determined, a mathematical model of linear programming is developed, aimed at increasing the organizational level of material flow management in construction organizations.

The construction organizations lack adaptive infrastructure. It is required to use more intensively SMART-technologies of design and construction. Purposes of this article: a) the system analysis of categories "competitiveness", "stability", "rating of the company" for the construction organizations; b) to construct and investigate economic and mathematical model of competitiveness of the construction organization; c) to determine parameters of self-organization of construction company; d) to construct an identification algorithm for model. These new tasks also answer the purposes of modern construction business, problems of forecasting of its development. Using methods of the system analysis and modeling, in work three levels of the analysis of construction business are considered: macrolevel (level of the state), mesolevel (level of the region) and microlevel (level of the company). For example, 10 various classes of competitiveness of construction companies are offered. It improves the classification used traditionally. The new economic and mathematical model on the basis of production functions of type of Cobb-Douglas is constructed. The algorithm of its identification on the basis of situational scenarios is also developed. The algorithm finds parameters which will allow to define competitiveness of construction company a priori. The offered research has a development, for example, is possible to use for the forecast of adaptation of the enterprise.
