| Tiivistelmä: | General methodologies for the minimal time routing problem are analyzed for a vessel travelling from an origin to a destination within stationary or time dependent seas, respectively. Local optimality considerations, combined with global boundary conditions, result in the efficient application of initial value methods to solve the associated two-point boundary value problems. In the stationary case, the velocity of the travelling vessel within each subregion depends only on the direction of motion. Variational calculus is used to derive the geometry of piecewise linear extremals. For the time dependent problem, the speed of the vessel within each subregion is assumed to be a known function of time and the direction of motion. |
