Application of the fuzzy sets theory to assessment of the large-scale investment projects

The paper considers the issues of how to assess the efficiency of the large-scale investment projects. We offer an approach to choosing a preferred project among competitive ones when making a decision on the selection of an investment project. The approach is grounded upon both the principals of system analysis applied in the fuzzy sets theory and expert technologies. Our special focus is on how to assess the investment costs and their fluctuations depending on investment risks while the preproject analysis is being carried out. To make our calculation, we use a simulated case-study on «Transportation Network Project for Russian Far North and Far East»
