In this paper we propose a mechanism of group ranking of contractors in the implementation of the construction project with the individual preferences, both in quantitative and qualitative indicators of their past performance, which allows you to create a rational organizational structure. In the course of the construction project developers have the difficult task of determining the priority of the contractors with which to work at different stages of schedule. Such a decision is always accompanied by the risk of selecting an unscrupulous contractor, defined as the probability of a certain level of losses. To reduce the risk of a similar class in the management decision-making process is used to describe the area of ​​feasible solutions using the technologies of system analysis. The results allow to make an informed group ranking of contractors in the performance of the construction project, not only in quantity but also in quality of their work, which significantly improves the quality of decision-making leadership development companies.
