Introduction: The most significant component in any bi-propellant rocket is the oxygen required for fuel combustion. This may account for up to 85%wt of the rocket propulsion reactants. Therefore, it is vital that locally produced oxygen is available from off-world sources to enable more economically viable space exploration to more distant regions of solar systems, and beyond. Our Moon in part...

the hub location decision is a long term investment and any changes in it take considerable time and money. in real situations, some parameters are uncertain hence, deterministic models cannot be more efficient. the ability of two-stage stochastic programming is to make a long-term decision by considering effects of it in short term decisions simultaneously. in the two-stage stochastic programm...

A fuel-supply system using movable fuel-supply vehicles (FSVs) is proposed and its performance is evaluated. Both FSVs and vehicles requesting fuel are equipped with networked sensors. The sensors in FSVs are location sensors, and those in vehicles requesting fuel are for determining the remaining amount of fuel and the location of the vehicle. The time from when a fuel request is generated unt...

We use station-level price data and a significant diesel fuel carbon tax reform to study who bears the economic burden of taxes. difference-in-differences strategy estimate pass-through large increase retail prices, where we compare prices faced by private motorists gasoline prices. find that on average taxes are less than fully passed through consumer which suggests consumers supply chain spli...
