Discrete optimization as decision support

It is fascinating that mathematical models and algorithms can be used to compute and suggest a good course of action when faced with a decision so complex that it is difficult for a human to grasp all aspects of it. For me, our research is about pushing the limits for when optimization can be of practical use, both with respect to how a problem is modelled, and through the development of efficient solution strategies. My research is within discrete optimization, with a special interest in decomposition methods, and the applications are mainly within scheduling and resource allocation.
