Bilevel optimization is a field of mathematical programming in which some variables are
constrained to be the solution of another optimization problem. As a consequence, bilevel …

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 …

Humanitarian relief logistics is one of the most important elements of a relief operation in
disaster management. The present work develops a multi-objective robust stochastic …

We apply new bilevel and trilevel optimization models to make critical infrastructure more
resilient against terrorist attacks. Each model features an intelligent attacker (terrorists) and a …

We study the problem of interdicting the arcs in a network in order to maximize the shortest s–
t path length.“Interdiction” is an attack on an arc that destroys the arc or increases its …

We describe new analytical techniques to help mitigate the disruptions to electric power
grids caused by terrorist attacks. New bilevel mathematical models and algorithms identify …

Facilities and their services can be lost due to natural disasters as well as to intentional
strikes, either by terrorism or an army. An intentional strike against a system is called …

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 …
