Description
Source code of the VISIR-2 ship weather routing model.
The Python-coded VISIR-2 model considers currents, waves, and wind to optimise ship routes via a graph-search method. It computes least-distance, least-time, and least-CO2 routes in a dynamic marine environment. The model was validated, and its computational performance is quasi-linear. Given the vessel performance curve, the model is generalisable across various vessel types.
