1. A system for use with a plurality of sensors within a domain for predictively modeling dispersion of a material through a medium within the domain, said system comprising: a storage portion having stored therein nomograph data; a processing portion operable to process the nomograph data; a graphical user interface connected to said processing portion; and an external interface connected to said processing portion and in communication with location data providers that are operable to provide to said processing portion, via said external interface, location data related to a location of an event corresponding to a presence of the material within the domain, wherein the nomograph data relates to domain data that corresponds to data of the domain and relates to medium data that corresponds to data of the medium within the domain, wherein said processing portion is further operable to process the location data and to provide, to said graphical user interface, display data relating to the nomograph data and the location data, wherein said graphical user interface is operable to display the display data to predictively represent possible dispersion of the material through the medium within the domain, and wherein said processing portion has an executable genetic algorithm stored therein that is operable to determine placement of the sensors to minimize detection time of dispersion of the material through the medium within the domain.
