Sea-going ships are autonomous complex objects that are intensively automatized due to safety and economic factors. The issue is complicated enough to entail a need for powerful methods such as Artificial Intelligence techniques. This repon gives a brief description of several problems of ship-building for which Artificial Intelligence techniques seem to be particularly suitable. They include: ...

This work deals with the Integrated Vehicle and Crew Scheduling Problem (VCSP) in urban mass transit. The Vehicle Scheduling Problem (VSP) consists in creating a daily routine of operation for a fleet of vehicles of a company so that all timetabled trips are covered and the operational costs of such activity reduced, making the best use of the fleet. In the Crew Scheduling Problem (CSP) each cr...

Regional bus scheduling is necessary to urban public transport that is complicated by the necessity of assigning trips that belong to several routes to buses located at different depots while reducing fleet size and operating costs. Considering the reality of emergencies that may interfere with the ability of vehicles to complete trips on time, it is reasonable to use fuzzy numbers to express u...

The routing and scheduling of vehicles and their crews is an area of increasing importance. In this paper, we describe a large scale vehicle scheduling and routing problem which is of great importance to parcel distribution companies. We devise a Breeder Genetic Algorithm capable of dealing with up to 10,000 transportation requests to be serviced by an inhomoge-neous fleet of vehicles within a ...

Route scheduling is a quite complicated process because it involves some determinant factors. Several methods have been used to help resolve the NP-hard problems. This research uses genetic algorithm to assist in optimizing ship scheduling, that where there are several ports to be visited by some ships. The goal is to divide the ship to go to a specific port so that each port is only visited by...
