A network modeling environment with a GIS-based graphical interface
The NetFlow Dynamics application is a network modeling environment consisting of algorithms to calculate flows on networks and a GIS-based graphical interface for performing simulations and viewing simulation results. Evolved from the national Transportation Fuels Model, NetFlow Dynamics instantiations connect to databases of any domain containing domestic and/or global network models and perform simulations of disruptive events. Each network/model specifies the nodes and edges of a network including the flow capacity of each edge, the storage capacity of each node, and the sources and sinks of the commodities flowing on the network. Specified changes in the capacity of one or more edges represent disruption of, or changes to, individual model components.
The long-term goal of the Global Energy capability is to develop and maintain modeling and analysis capability to forecast how energy infrastructure systems respond to acute or chronic stresses and how well these infrastructures deliver services under these stresses. We envision the final state to be a web-based, multi-algorithm environment for computation and analysis of adaptive flows of energy on infrastructure networks by a consortium of energy analysts. The consortium setting would enable a common simulation approach, more peer review, comparison of results, and sharing of data collection and synthesis.
