Networks can also be a useful way of modeling the spread of a wildfire. A landscape can be divided into cells and the midpoints of the cells form the nodes of the network. Arcs connect nodes to their neighbors and the weight on an arc represents the time a fire takes to travel between nodes, based on landscape and weather characteristics. Thus, we have applied network interdiction to the problem of allocating resources to a landscape prior to a fire in order to prevent fire outbreak.
A former Ph.D. student of mine has developed an integer programming model for computing the worst-case vulnerability of a fire. He also examined how to mitigate against pyro-attacks and how to model pyro-terror vulnerability with an explicit initial response phase model. This work was funded by the Department of Homeland Security.
I am also working on a paper on using mixed-integer programming to design incentive structures to encourage private landowners to take fuels reduction actions on their lands to prevent the spread of fires. This work is funded by the Joint Fire Science Program. In the future I will continue to seek funding from the Joint Fire Science Program on a yearly basis for topics centering on the idea of using network interdiction to manage wildfires.
Another former Ph.D. student of mine has developed an approach for optimally locating satellite ground stations to maximize the data collected in the aftermath of a wildfire. He has also studied how to optimize satellite orbits in order to detect wildfires and gather data. In the future I plan to seek funding from the National Science Foundation for this work.
