Patent ID: 7308374

Claim:
A method of identifying sites for one or more detectors in a facility, said facility represented with a plurality of zones, comprising: providing a plurality of signals S i,j , each signal S i,j representing an effect in a zone j in response to a release of a predetermined amount of a contaminant in a zone i for one or more flow conditions, wherein zone i and zone j are identical or distinct zones selected from the group consisting of said plurality of zones; determining a limiting case signal for each flow condition of said one or more flow conditions for each candidate architecture of a plurality of distinct candidate architectures having one or more detectors in one or more zones as one or more candidate zones, respectively, said limiting case signal being a smallest system signal of a system set comprising a plurality of system signals, each of said system signals being associated with said release in a distinct zone of said plurality of zones, each system signal being a maximum one of said signals representing said effect in said one or more candidate zones from said release in said distinct zone of said plurality of zones for said each flow condition; determining, for each candidate architecture, a robust limiting case signal based on a minimum of said each limiting case signal for said each flow condition; and selecting one of said plurality of candidate architectures as the siting architecture based on said robust limiting case signal of said each candidate architecture, identifying the sites of said siting architecture as the sites for said one or more detectors in said facility.
