Speaker: Dr. J. Cole Smith

Location: Engineering North 450

Abstract: We study a dynamic assignment interdiction game involving two agents, a userand an attacker. The user wishes to assign a set of tasks at the minimum cost, and theattacker seeks to interdict a subset of arcs to maximize the user's objective. The completion time for each task is one period and, because of resource constraints, only one task can start at any time. The assignment costs and interdiction impacts vary over time. At any time in the game, the attacker can interdict arcs subject to a budget (cardinality) constraint and any interdicted arc can still be used by the user at an increased assignment cost. The goal is to find an optimal sequence of assignments, coupled with the attacker's optimal interdiction strategy. We prove that this problem is strongly NP-hard, even when the attacker can interdict only one arc. We propose an exact exponential-state dynamic-programming algorithm for this problem as well as lower and upper bounds on the optimal objective function value. One class of these bounds is based on classical interdiction and robust optimization models, and the other on exact solutions to variations of the dynamic assignment interdiction game. This is joint work with Dr. Jorge Sefair, Assistant Professor at Arizona State University.

Speaker Bio: Dr. J. Cole Smith is Professor and Chair of the Industrial Engineering department at Clemson University. His research has been supported by the NSF, DARPA, AFOSR, DTRA, and the ONR, and he has spent one summer as a distinguished visiting professor in the National Security Agency¹s summer program in operations research technology. His research regards mathematical optimization models and algorithms, especially those arising in combinatorial optimization. Dr. Smith has had the pleasure of collaborating with colleagues across many different disciplines, including Mathematics, Ecology, Psychology, Computer Science, and Biomedical Engineering. His awards include the Young Investigator Award from the ONR, the Hamid K. Elden Outstanding Young Industrial Engineer in Education award, the Operations Research Division Teaching Award, the 2014 Glover-Klingman prize for best paper in Networks, and the best paper award from IIE Transactions in 2007.
