Evacuation modelling: finding the best time (and way) to get going

Reports from the Philippines reveal a lack of typhoon preparation and evacuation efforts.

When to evacuate – and how – spells the difference between life and death. As we know, typhoons can cause widespread flooding of surrounding areas, and don’t just affect what lies in the path of the storm. Planning an evacuation is a game against nature.

Typhoon Haiyan (and similar events around the world) indicate that people do not play this game well … but computers do.

VRP 2013 – Computational aspects of vehicle routing

I  taught a workshop on computational aspects of vehicle routing during the VRP 2013 spring school in Angers, France. The course attempts to answer the following questions:

  • What is time and space complexity? Why is it important?
  • How to represent a solution efficiently?
  • What are the main bottlenecks and how to avoid them?
  • How do parallel computing work? Why, when, and how to parallelize?
  • How to design flexible and reusable code?
  • How to avoid reinventing the wheel?

VRP2013: European Spring School on Vehicle Routing

VRP2013: European Spring School on Vehicle Routing is a one-week, full-immersion institute gathering Ph.D. students and young researchers working on the field of vehicle routing.

The academic program is made up of 4 academic modules and 2 workshops. In addition to the academic program, the spring school includes an active social program conceived to help participants developing personal links that may foster future academic collaborations.

The spring school will be hosted by the Institute of Applied Mathematics (IMA) of Université Catholique de l’Ouest in Angers (France) from May 20 to May 24, 2013. The spring school is open to all Ph.D. students completing a dissertation on vehicle routing and young researchers working on the field. Participants are invited to present their research in poster sessions during the coffee breaks. Presenting a poster is not mandatory.

Participants should apply for a place at the spring school before January 30, 2013. The number of participants is limited. Places will be assigned according to a FIFO discipline giving priority to Ph.D. students and participants presenting a poster. Participants from outside Europe are welcome to apply.
