ABSTRACT

Logistics is a process of distribution network management and optimization of the flow of resources. Therefore, logistics management benefits from using optimal product transportation. The transportation locations of the economic world are undergoing a dramatic change with the emergence of new Arctic seaways (Wilson et al. 2004). The melting of sea ice in the northern hemisphere is being observed with great attention. As a result of both greenhouse effects and seasonal fluctuations of long-term average temperatures, a historical opportunity presents itself to extend maritime transport over the Arctic region. For instance, the Northern Sea route shortens the Yokohama-London distance via the Suez Canal from 11.447 to 7.474
