Bilevel optimization is a very active field of applied mathematics. The main reason is that
bilevel optimization problems can serve as a powerful tool for modeling hierarchical …

This paper discusses the development of interdiction optimization models and algorithms,
with an emphasis on mathematical programming techniques and future research challenges …

We propose a stochastic optimization approach for the storage and distribution problem of
medical supplies to be used for disaster management under a wide variety of possible …

Vulnerability to sudden service disruptions due to deliberate sabotage and terrorist attacks is
one of the major threats of today. In this paper, we present a bilevel formulation of the r …

Supply systems are subject to disruptions whose impact may not remain confined, but might
actually propagate across the network. We consider the problem of optimally protecting a …

We present an exact algorithm for the bilevel mixed integer linear programming (BMILP)
problem under three simplifying assumptions. Although BMILP has been studied for …

Human trafficking is a complex transnational problem for society and the global economy.
While researchers have studied this topic in a variety of contexts, including the criminology …

The illicit wildlife trade is a pervasive and global problem that has far-reaching impacts on
both society and the environment. Aside from threatening numerous species around the …

This paper (a) describes a defender-attacker-defender sequential game model (DAD) to
plan defenses for an infrastructure system that will enhance that system's resilience against …

We describe a rudimentary branch-and-cut algorithm for solving integer bilevel linear
programs that extends existing techniques for standard integer linear programs to this very …
