In this study, a mathematical model that integrates spatial and temporal dimensions is developed for strategic planning of future bioethanol supply chain systems. The planning objective is to minimize the cost of the entire supply chain of biofuel from biowaste feedstock fields to end users over...

Beijing could be an attractive region to initiate a hydrogen infrastructure for transportation. Air quality is poor, oil imports are soaring, and there is a desire to introduce innovative responses for the 2008 Olympics. If Beijing were to proceed to build hydrogen infrastructure before and...

Southern California has been proposed as a likely site for developing a hydrogen refueling infrastructure. In this paper, we apply dynamic programming to identify optimized strategies for supplying hydrogen over time in Southern California. GIS-based traffic data are used to model the location...

This paper presents the results of a model of hydrogen production from waste biomass in California. We develop a profit-maximizing model of a biomass hydrogen industry from field to vehicle tank. This model is used to estimate the economic potential for hydrogen production from two waste biomass...

Many important decision making processes in transportation planning and engineering involve repetitive computation of network performance, measured by total network delay, throughput, network efficiency, etc. The computational complexity imposed by repetitive evaluation of these measures,...

The problem of hydrogen station location is often studied through understanding refueling behavior or reviewing the experience of gasoline stations. Driven by the notion "where you drive more is where you more likely need refueling", this paper develops a new approach where station siting is...

Proceedings of the 4th Annual Asia Pacific Conference on Transportation and the Environment This paper describes the on-going Hydrogen Infrastructure Transition (HIT) modeling efforts with the Beijing case study. HIT uses dynamic programming to generate optimal decisions on when, where, at what...
