A Strategic–Tactical Collaborative Route Decision System for the Arctic Northeast Passage
2026
Overview
The complex and variable sea ice environment constrains the safety and efficiency of Arctic shipping. To address the limitations of existing methods in balancing long-term planning with dynamic route adjustment ahead of the vessel, this paper develops an Arctic route decision-making system based on strategic–tactical coordination. The system establishes a “Global Guidance–Local Correction” collaborative mechanism: the strategic module utilizes medium-range climate forecast data to generate a set of daily baseline routes over a 30-day forecast window, providing macro-scale route guidance and feasibility assessment for the voyage; meanwhile, the tactical module integrates high-spatiotemporal-resolution sea ice concentration (SIC) data to screen local high-SIC areas that constrain navigation and execute tactical route correction ahead of the vessel. Experimental results demonstrate the feasibility of integrating long-term global planning with dynamic route adjustment. This provides a feasible route planning framework for integrating long-term strategic guidance with tactical-level dynamic adjustment under complex Arctic ice conditions, offering technical support for future intelligent Arctic navigation systems.
