Research

Current strategies to place gas sensors in industrial settings are based upon heuristics or semi-quantitative approaches. Optimal sensor placement is difficult due to the large number of unknown variables that influence the risks associated with gas leaks. Heuristic and semi-quantitative approaches can give results that are far from optimal in terms of cost and risk reduction. This research presents adaptations to a sensor placement formulation which incorporate sensor voting schemes and probability of sensor failure. In many instances, release events are not considered detected until multiple detectors acknowledge the release. Therefore, modified formulations must be developed to take into account this need for sensor voting. Additionally, this research considers adaptations to the original sensor placement formulation that account for the imperfect sensor, or the sensor that has some probability of failure.
