摘要：Introduction. In the field of implementation of integrated programs of housing construction as a promising direction from the point of view of solution of the most important problems of modern development of the construction industry (intensive growth of urban areas, low quality and high cost of new housing, poor infrastructure), the key task has been set: rationale of the characteristics of the complex of construction sites taking into account interrelations between the number and characteristics of residential buildings and infrastructure facilities. Based on the results of the analysis of the relevant scientific literature, the conclusion was made that the existing tools are limited and fully take into account the key features of the implementation of integrated programs of housing construction. Relevance of research which objective is development of a method of substantiation of characteristics of a complex of construction sites is substantiated. Materials and methods. The organizational and process characteristics method of the complex of construction sites on the basis of linear fractional programming, which implies the determination of the optimal number of housing construction sites and infrastructure facilities in the context of different instances and categories by the criterion of maximizing the profitability index of the corresponding construction project was developed. The key elements of the developed method are optimization models, which are linear relatively unknown variables and therefore implemented using simplex method in modern software environments of optimization modeling. Results. The developed method is implemented on a practical example using Microsoft Excel software environment and the “Solution Finder” add-in. As a result of performance of corresponding calculation procedures, concrete values of quantity of sites and infrastructure facilities within the limits of the building project have been received. Conclusions. On the basis of adequate results obtained from the implementation of the proposed methodology on practical example, the conclusion was made about the high practical significance of the developed tool. The main shortcomings of the developed method are revealed, connected with the absence of consideration of factors of influence of features of a transport infrastructure and technological resources within the limits of construction procedure on characteristics of the project. In order to eliminate the identified shortcomings, it is planned to improve the methodology at further stages of the research.
