Integrated problem of ship route planning

Planning and realization of ship route is a complex problem, which consists of elements from different disciplines. It is necessary to take into account: the formal requirements, the organization of traffic in restricted areas, exploitation limitations of the ship; economic issues relating to the costs of fuel and the costs associated with the possible unscheduled reaching the ship at the port of destination and waiting for unloading. It is important to maintain safety conditions related to extreme weather conditions. As the sailing is done on the changing weather conditions, considerable issue is the problem associated with the acquisition, processing and integration of weather data. Issues connected directly with the procedures of route computation are also important - the choice of optimization algorithm, matching the speed characteristics, the state of load. Increasingly being taken into account as restriction of navigation has to be the threat of piracy and terrorism. In the planning and realization of a ship voyage important issue is so called human factor and thus the experience of the master, which will include a decision as to the extent of detail of route planning, taking into account the restrictions importance and eventual adoption or not the proposed route

A competitive multipopulation evolutionary algorithm for ship trajectory planning

Determining the optimum trajectory for a ship between its current position and the assumed target point, done taking into account navigational situations which the ship is to face when covering this trajectory, was the subject of numerous publications but has not been finally solved yet. The authors propose to determine the optimum and safe ship trajectory using a competitive multipopulation evolutionary algorithm. The proposed algorithm will also allow the trajectory to be corrected depending on a current navigational situation, for instance the appearance of collision threat. Practical application of the algorithm would considerably relieve navigator's work, and contribute to the increase of safety at sea and reduction of ship operation costs.
