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...

Abstract In the classic Vehicle Routing Problem (VRP) a fleet of of vehicles has to visit a set of customers while minimising the operations’ costs. We study a rich variant of the VRP featuring split deliveries, an heterogeneous fleet, and vehiclecommodity incompatibility constraints. Our goal is twofold: define the cheapest routing and the most adequate fleet. To do so, we split the problem in...

This paper presents a model to coordinate the pricing and fleet management decisions of a freight carrier. We consider a setting where the loads faced by the carrier over a certain time horizon are deterministic functions of the prices. We want to find what prices the carrier should charge so that its pricing and fleet management decisions jointly maximize the profits. Our solution approach is ...

This paper describes the current evolutions and perspectives of the FTS real-time executive as the colonne vertébrale of the Ircam “Real-Time Platform” project, which is a software oriented continuation of the “Ircam Musical Workstation” project.

The majority of actors in the Norwegian fisheries consider recruitment of fishers to be the main future challenge for the Norwegian fishing fleet. As fleet recruitment is a highly politicized field, the problem of how to mitigate the recruitment problem is a subject of heavy debate. Some argue that recruitment problems are caused by low fleet profitability, while others argue that recruitment p...

This thesis aims to elucidate real option thinking and real option valuation techniques for innovative technology investment. Treating the fuel cell R&D investment as a real option for General Motor's light passenger vehicle fleet, the thesis presents a 3-step approach to value the R&D and its influence on the fleet value, in which the uncertainties and managerial flexibility are proactively ac...
