When managing the processes of implementing investment and construction projects, conditions of varying levels of uncertainty arise, giving rise to risky situations. Ignoring risk situations when implementing investment and construction projects leads to the emergence of risk combinations and increased risk costs and eliminating their consequences. Determining the risk intensity of a risk situation (combination) is becoming increasingly relevant; in this regard, the relevance of developing a model for monitoring the total cost of risks of investment and construction projects is increasing.
The purpose of the study is to develop an economic and mathematical model for monitoring the total cost of risks of investment and construction projects. It has been established that in the military sphere, the amount of material costs for product development is significantly influenced by risks associated with the internal and external environment. This article examines existing models of investment and construction projects and identifies their distinctive aspects. The novelty of the ongoing research lies in the author’s approach to developing a model for monitoring the total cost of risks at various stages of the life cycle of investment and construction projects. The practical significance of the results lies in the possibility of monitoring the total cost of risks of investment and construction projects at all stages of its life cycle, estimating, based on the proposed model, the final total cost of investment and construction projects by summing up all the total costs of risks of the stages of investment and construction projects. These measures are aimed at preventing a risk situation or risk combination and ensuring the implementation of investment and construction projects. A design-process approach to feasibility studies and process management of investment and construction projects is proposed.
Recommendations for applying the results obtained are the need to assess the total cost of risks of investment and construction projects at all stages of its life cycle in order to determine the source of its occurrence.
