Robust optimization of water infrastructure planning under deep uncertainty using metamodels

Planning Under Temporal Uncertainty Using Hindsight Optimization

A robot task planner must be able to tolerate uncertainty in the durations of commanded actions and uncertainty in the time of occurrence of exogenous events. Sophisticated temporal reasoning techniques have been proposed to deal with such issues, although few existing planners support them. In this paper, we demonstrate the capabilities of a much simpler technique, hindsight optimization, in w...

Robust Optimization of Multi-Period Production Planning Under Demand Uncertainty

Many-Objective Robust Decision Making for Water Supply Portfolio Planning Under Deep Uncertainty

Portfolios of market-based instruments have been shown to improve the reliability of water supplies, using simulations that utilize a single best estimate of distributions of data to evaluate performance. However, the estimates of problem information and likelihoods could be incorrect, especially when planning for climate change, which can modify streamflow availability, or projecting the traje...

Evacuation Transportation Planning Under Uncertainty: A Robust Optimization Approach

This paper considers evacuation via surface transportation networks in an uncertain environment. We focus on demand uncertainty which can lead to significant infeasibility cost during evacuation, where loss of life or property may appear. We develop a robust linear programming model based on a robust optimization approach where hard constraints are guaranteed within an appropriate uncertainty s...

Robust Simulation-optimization Methods Using Kriging Metamodels

Acknowledgements Now that I become closer and closer to the end of this adventure, I would like to deeply thank some people who helped me — in different ways and at different stages of my PhD — to achieve this goal. First of all, I want to thank my advisors: Carlo Meloni, for having introduced me to the fascinating world of research, for his being always so supportive to me, and for his willing...
