Structural analysis of factors for revitalizing Lena river logistics using ISM method

Currently, inland water transport is the main mode of transport in the Republic of Sakha (Yakutia). The Lena remains the main river connecting Yakutia with the federal transport infrastructure. However, the state of the Republic's transport infrastructure does not meet the needs of its economy The infrastructure limits the effective realization of the industrial and resource potential and use of the geographical position of the Republic of Sakha. Therefore, to provide an insightful analysis of the factors affecting the logistics of the Lena River, we conducted a detailed analysis of the current problems of the inland waters of the Republic. This article analyzes the logistics of the Lena River and presents an assessment of the problems hindering the process of modernizing the inland water transport of the Republic of Sakha. Analyzing the factors for revitalizing the Lena River logistics through the Interpretative Structural Modeling method revealed the region's main water transport logistics problems. Through the literature review, 12 key factors affecting the logistics of the Lena River were identified, and interrelationships among them were represented. The results illustrate that inland water transport of the Republic requires the development of transport infrastructure and financial support from the state to implement republican targeted programs. Therefore, this study is important in both academic and practical aspects.
