Orkun Baycik is an honorable mention at the IISE Annual conference Doctorial Colloquium for her poster titled, “Interdicting Layered Physical and Information Flow Networks ”Orkun’s research focuses on an interdiction problem on two interdependent networks. In this bi-level program, the objective of the defender is to maximize the physical flow and the objective of the attacker is to minimize this maximum amount. The existence of interdependencies results in a discrete inner problem. They reformulate this problem using duality and obtain a single-level formulation. They apply this technique to combating against illegal drug trafficking and perform cyber-based vulnerability analysis of supply chain networks and infrastructure systems.
