trade over the last few years through the globalization process has triggered the demand for more efficient maritime services. New challenges have to be met by the shipping companies in terms of efficient schedules and routes of the vessels. In the quest to achieve that a discrete event simulation model

of the service routes designed depends on the paths chosen to ship the cargo. We present an integrated model, a mixed integer linear program, to solve the ship scheduling and the cargo routing problems simultaneously. The proposed model incorporates relevant constraints, such as the weekly frequency constraint

Most optimization-based decision support systems are used repeatedly with only modest changes to input data from scenario to scenario. Unfortunately, optimization (mathematical programming) has a well-deserved reputation for amplifying small input changes into drastically different solutions. A

horizon by which all deliveries must be made and vessel capacities. The objective is to minimise the overall operation cost, where all customers are satisfied. Two types of routing and scheduling are considered, one called single-cargo problem, where only one cargo can be loaded into a ship

Ships that sail at high speeds emit a higher amount of air emissions on a per tonne-km basis than ships that go slower. As the goal of environment-friendly shipping is high on the agenda of the IMO, the European Commission and many individual coastal states, reduction of emissions, both from
