Paul Kantor
Layered screening at public events: Models and challenges

Coauthors: Endre Boros, Fred Roberts, Brian Thompson


Public events must screen against many threats. Stakeholders’ interests diverge - owners seek revenue, patron experience, and safety against minor disturbances, and major attacks. Patrons seek to enjoy the game, to drink, etc. Events are protected by layers of agents (county police, city police, stadium workers etc.) under distinct authorities, and each with its own screens. For each "violation'' there are several terminal remedies. A guest with a knife, or beer may be asked to surrender the object, or to go home. A cost matrix C(a,s;J) depends on the state of the patron (s=harmless; … etc.) and the terminal action imposed by the authorities (a=confiscate but admit; send home; arrest; etc.), as seen by stakeholder class J.
Given imperfect screens (metal detector; wanding; dogs; pat-down; etc.) we seek optimal routing rules for arriving patrons. Assignment to further screens, and choice of actions, depends on results of earlier screens. One screened for metal may be labeled (admit; wand; pat-down; etc.). We need throughput for all patron classes, with acceptable costs for all. We give a polytope approach, a dynamic
programming approach, rigorous results, and simulations.
