Planning the transition period for the adoption of alternative fuel-technology powertrains is a challenging task that requires sophisticated analysis tools. In this study, a system dynamic approach was applied to analyze the bi-directional interaction between the development of the refueling station network and vehicle sales. Besides, the developed model was used to estimate the transition cost...

a r t i c l e i n f o Given the recent trend of raising fuel cost and the increased time-sensitiveness of shippers, an extensive pressure is placed on the motor-carrier industry to meet the time-constrained customer demands at minimum fuel cost. We propose a decision support system that allows motor carriers to route each vehicle such that the vehicle not only visits all the customers in time (...

The UK nuclear power industry is predominantly based on gas-cooled, graphite moderated reactors with their being 20 operating and 6 shutdown Magnox reactors. The radioactive graphite issues associated with the Magnox reactors relate mainly to the reactor core graphite but, at two of the stations, there is also another graphite waste stream which results from the handling of their particular des...

The paper addresses the problem of entry barriers for a new technology – hydrogen powered cars or cars with fuel cell engines – if the network of its filling stations is missing or thin. We use Hotelling’s model of product differentiation to characterize a situation where an incumbent firm produces the old technology, compatible with the existing network of filling stations, and an entrant, who...

Optimal location problems identify the best sites to set up new facilities for providing service to its users. Majority of the existing work in this space assumes that the users are static and the datasets are small. Such assumptions are too restrictive and unrealistic for reallife services such as setting up of fuel stations, upgradation of cellphone base-stations, etc. The placement of such s...

Wildfire risk assessment has traditionally been carried out using models based on meteorological parameters measured at spatially sparse weather stations. Remote sensing techniques can offer a cost effective way of esimating the required parameters such as fuel moisture and fuel temperature in near-real time. Moreover remote sensing can provide wide area coverage and thus circumvent errors intr...
