SYSTEM MODELING AND DEVELOPMENT THE MECHANISM OF INVESTMENT DECISIONS IN THE CONSTRUCTION COMPLEX OF THE REGION
PURPOSE. In this article we presented analysis of the possibilities of assessing the underfunding of investment activity of regional economy and shows the advantages of a systematic approach to solve this problem under conditions of quite high uncertainty. The models and algorithm to realize the risk assessment problem through system modeling and development of the elements of the investment solution mechanism in the construction complex of the region. METHODS. As the research tools we used economic-mathematical apparatus for modeling situations, methods of analyses of the initial information. The results of calculations on the model are presented, which reflect the effectiveness of the proposed method and methods for assessing the insolvency of economic reconstruction projects implemented into the construction complex of Irkutsk region. We considered the conditions for participation of business in construction, and proposed the offeres for improving the existing order. RESULTS AND THEIR DISCUSSIONS. The advantages of the model and algorithm for estimating the risk of underperforming the net present value of projects that are the basis of system plans and the mechanism of investment decisions are revealed. CONCLUSIONS. We presented the conclusions, which reflect the effectiveness of the application of system modeling of the development of the mechanism of investment solutions in the construction complex of the region.
