In this paper, we discuss the problem of peer-to-peer (P2P) refueling of satellites in a circular constellation. In particular, we propose a cooperative P2P (C-P2P) refueling strategy, in which the satellites involved in P2P maneuvers are allowed to engage in cooperative rendezvous. We discuss a formulation of the proposed C-P2P strategy and a methodology to determine the optimal C-P2P assignme...

We consider the problem of finding the least cost route for an aircraft between a predetermined starting and target location while ensuring either enough fuel is on board or acquired en route via refueling for completion of the route. Other considerations of this problem include adherence to regulations for threat and no-fly zones and to regulations for the minimum fuel needed on an aircraft in...

This work expounds on implementing an effective dynamic ðs; SÞ policy to solve a liner shipping refueling and speed determination problem under both bunker prices and consumption uncertainties. While solving an optimization model which incorporates a continuous distribution is extremely challenging, we use sample average approximation method to solve it. However, the resulting problem is still ...

The Association of American Railroads (AAR) has recently completed development of the first industry standard for a reliable, spill-proof locomotive refueling system. The Locomotive Fueling Interface Standard (LFIS) is an open, non-proprietary standard that incorporates a combination of the latest, proven refueling equipment technologies adapted for use in the railroad environment. The LFIS was...

Given the limited driving range of battery electric vehicles and lack of sufficient charging infrastructure, locating charging stations is an important decision problem to enable long-distance travels by battery electric vehicles. This paper considers an important political factor in such location problems: the equitable access to charging stations among geographical regions. We propose three t...

With the introduction of alternative fuel vehicles into the transportation system, the refueling station location research has been touted in the literature. The flow refueling location problem (FRLP) locates p stations in order to maximize the flow volume that can be accommodated in a road network respecting the range limitations of the vehicles. This paper introduces the hybrid charging stati...

The United States Air Force Air Mobility Command (AMC) is responsible for managing hundreds of airlift and air refueling missions every week on a global scale. Allocating airframes and flight crews to individual missions is a large and complex problem. We have built the AMC Airlift and Air Refueling Allocator to assist planners and schedulers in this task, and the tool is currently transitionin...

Motivated by the urgent demand for the electric vehicle (EV) fast refueling technologies, battery swapping and charging stations (BSCSs) are envisioned as a promising solution to provide timely EV refueling services. However, inappropriate battery charging operation in BSCSs can not only incur unnecessary high charging cost but also threaten the reliability of the power grid. In this paper, we ...

This paper presents a dynamic programming (DP) model of an electric utility’s optimal policy for operating a nuclear power plant (NPP). The utility chooses the level of capacity utilization of the NPP as a function of signals about the NPP’s current operating state. In each period the utility must determine whether or not to operate the reactor, or shut it down for preventive maintenance or ref...

Fuel spillage during locomotive refueling is expensive, as is maintaining spill collection and containment systems, and waste treatment costs. The Association of American Railroads has developed the first standard for a locomotive refueling system for North American railroads. The locomotive fueling interface standard is an open, non-proprietary standard designed to prevent fuel spillage. Proto...
