This paper addresses task assignment in the coordination of a fleet of unmanned vehicles by presenting two decentralized algorithms: consensus-based auction algorithm (CBAA) and its generalization to the multi-assignment problem, consensus-based bundle algorithm (CBBA). These algorithms utilize a market-based decision strategy as the mechanism for decentralized task selection, and use a consens...
Car sharing services promise “green” transportation systems. Two vehicle technologies offer marketable, sustainable sharing: autonomous vehicles (AVs) eliminate customer requirements for car pick-up and return, and battery electric vehicles entail zero emissions. Designing an autonomous electric vehicle (AEV) fleet must account for the relationships among fleet operations, charging station (CS)...
This paper addresses task allocation to coordinate a fleet of autonomous vehicles by presenting two decentralized algorithms: the consensus-based auction algorithm (CBAA) and its generalization to the multi-assignment problem, i.e., the consensus-based bundle algorithm (CBBA). These algorithms utilize a market-based decision strategy as the mechanism for decentralized task selection and use a c...
The Aircraft Assignment problem is the problem of assigning flights to aircraft in such a way that some operational constraints are satisfied, and possibly that some objective function is optimized. We propose an approach to aircraft assignment which captures all operational constraints, including minimum connection times, airport curfews, maintenance, and preassigned activities. It also allows...
This study concerns the deployment of large numbers of container transporting vehicles on a network consisting of (dedicated) roads and logistic sites such as container terminals. Each site is managed autonomously by a site manager. The fleet of vehicles is deployed by a fleet manager. On request of the site managers, the fleet manager allocates vehicles to be hired by the site managers. Next, ...
Fleet assignment models are used by many airlines to assign aircraft to flights in a schedule to maximize profit [Abara 1986, Hane et al 1995]. A major airline reported that the use of the fleet assignment model increased annual profits by more than USD100 million [www.informs.org, 2002] a year over three years. The results of fleet assignment models affect subsequent planning, marketing and op...
In this preliminary work, a fleet management problem that occurs in container transportation industry is presented. From the carrier perspective, the present and future operations costs to minimize can be divided in three components: the routing costs, the resource (i.e., driver and truck) assignment costs and the container repositioning costs (i.e., the costs of restoring a given container fle...
the aim of this paper is to present an efficient method for a rail freight car fleet sizing problem. this problem is modeled mathematically as a multi-period, dynamic and multi-objective, in which the rail freight wagons are assumed to be heterogeneous. demands for different wagons and all travel times are assumed deterministic. in order to increase the utilization of the available wagons in th...
