Assignment of aircraft types, each having different seat capacity, operational expenses and availabilities, critically affects airlines’ overall cost. In this paper, we assign fleet types to paths by considering not only flight timing and passenger demand, as commonly done in the literature, but also operational expenses, such as fuel burn and carbon emission costs associated with adjusting the...

Ride-sharing services are transforming urban mobility by providing timely and convenient transportation to anybody, anywhere, and anytime. These services present enormous potential for positive societal impacts with respect to pollution, energy consumption, congestion, etc. Current mathematical models, however, do not fully address the potential of ride-sharing. Recently, a large-scale study hi...

In the era of smart manufacturing, autonomous mobile robots have become affordable for numerous companies, although fleet management remains a challenging problem. A novel approach is proposed, supporting solution vehicle assignment The method relies on adaptive workstation clustering that considers not only complex environment layout, but also main characteristics material flow. technique comb...

Full terms and conditions of use:

Collaborating unmanned aerial vehicles can efficiently perform surveillance, mapping, and other tasks without human risk. Currently deployed unmanned aerial vehicles demonstrate a need for increased autonomy and cooperation. We present a software architecture and UAV hardware platform that have demonstrated single-user control of a fleet of aircraft, distributed task assignment, and vision-base...

Stringent federal and state programs along with technology innovation have resulted in declining emissions from static sources (e.g. power plants) and are projected to meet national quality standards by 2025. The same cannot be said for mobile sources of emissions from flight operations at airports. In the absence changes in airport operations, the forecast rates of growth in flight operations ...

As an emerging variant of the vehicle loading problem, the heterogeneous multi-type fleet vehicle loading problem in finished vehicle logistics (HVLP-FVL) is modeled and solved. The HVLPFVL maximizes the total profit of a vehicle fleet where different models of finished vehicles result in different profits and routing costs are considered based on distance travelled. Addressing the vehicle stru...

Paper aims This study presents several business analytics tools that allow improving the tactical planning of collection process for a Colombian solid-waste management company. Originality The extant literature operations research/analytics applied to these systems focuses on facility location or vehicle routing. Tactical decisions are seldom studied in devoted waste systems. By contrast, focus...
