Auburn University's Department of Industrial and Systems Engineering will host a seminar by Scott Schultz, associate professor of industrial engineering at Mercer University, on Thursday, Nov. 5, at 4:30 p.m. in 1103 Shelby Center. Schultz will present "Scheduling Radar Warning Receivers (RWRs)," and describe how to model the scheduling problems that these small aircraft devices detect. RWRs are designed to detect incoming radar signals, identify and characterize the signals of a specific threat and alert crewmembers about the threat. Schultz's seminar is part of the department's fall seminar series.
In order to account for threats, an RWR moves among frequency bands detecting emitted energy, which makes the decision of length of time to dwell on the bands and the searching sequence a challenge. Schultz will address this problem by describing how it can be modeled as the coincidence of periodic pulse trains, using a simulated annealing meta-heuristic to find the best RWR schedules that minimize detection time of threats. He will also describe how the simulated annealing (SA) approach can improve on a simple heuristic and the ways in which the probability of intercept theory is being used to improve computational performance.
Schultz's teaching and research interests include operations research, simulation, production control and scheduling, operations management and management information systems.
