Tug fleet optimisation algorithms can be designed to solve the problem of dynamically positioning a fleet of tugs in order to mitigate the risk of oil tanker drifting accidents. In this paper, we define the tug fleet optimisation problem and present the details of a receding horizon genetic algorithm for solving it. The algorithm can be configured with a set of cost functions such that each con...

Public service fleets offer an attractive option for introducing new renewable fuels on a large scale, which allow for the reduction of both greenhouse gas emissions and exhaust air pollutants. This study examines the use of biomethane (bio-CNG) and compressed natural gas (CNG) for part of the bus fleet in Dublin, Ireland. The emissions produced from the 2008 fleet based at one of the city’s se...

Even with the rapid changes in the level of complexity and the uncertainty of the environment in which Belgian sea fisheries operate, fisheries management in Belgium is still mainly based on restrictive policy instruments founded in the biological approach of fisheries management science. Since they will continue to play an important role, this paper evaluated changes in three restrictive polic...

This paper proposes a sequential optimisation approach for addressing complex real world problem of dispatch planning and freight loading set highly irregular products with heterogeneous fleet trucks. The focuses on the case goods 'low-density values', varied large travel distances. proposed is based two-phase strategy: first optimises space assignment process inside trucks to each type product...
