PROJECT OF THE TRANS-SIBERIAN RAILWAY RECONSTRUCTION AS AN OBJECT OF SOCIAL EFFICIENCY EVALUATION

We consider the problem of social efficiency evaluation concerning the project of the Trans-Siberian Railway reconstruction. This project is to be realized in the situation of strategic (fundamental) uncertainty. Existing tools are not sufficient for solving this problem (because of qualitatively different nature of the project as compared with those abroad, much higher degree of uncertainty, and the lack of estimates for a number of necessary norms). Our study aims at development of an approach that would be adequate to the problem under consideration. We developed a two-level model for investment decision-making for appraisal and selection of a variant of the large-scale project. The upper level of this model bases on the macroeconomic approach (with the use of a specialized version of the Inter-Sector Inter-Region Optimization Model); the lower level bases on the microeconomic approach. As opposed to the foreign practice, the efficiency evaluation and selection of a variant of the transport project is top-down. End-to-end taking uncertainty into account is implemented. A tool for this is the scenario approach on the upper level, and the fuzzy set theory at the lower one
