Creating a relative suitability score for school buildings as evacuation shelters

Joanna P Faure Walker30 October 2020

A new paper published in Natural Hazards provides a method and worked case study from the Philippines for creating a relative suitability score of school buildings as use for evacuation shelters.

Tsioulou et  al., 2020, A method for determining the suitability of schools as evacuation shelters and aid distribution hubs following disasters: case study from Cagayan de Oro, Philippines

How can we make a decision based on multiple criteria?  How can we take qualitative expert opinions and create a quantitative comparison of the importance of different factors for decision-making?  What factors should be considered when evaluating the relative suitability of different buildings as evacuation shelters?  How can we identify which buildings could benefit most from cost-effective improvements? What do you think about whether school buildings should be used as evacuation shelters?

Alexandra Tsioulou (Willis Tower Watson, formerly UCL IRDR), Joanna Faure Walker (UCL IRDR), Dexter Sumaylo Lo (Xavier University, Cagayan de Oro) and Rebekah Yore (UCL IRDR and Rescue Global), as part of the PRISMH project, carried out expert opinion questionnaires and used the Analytical Hierarchy Process to create weightings of different criteria that should be considered when evaluating the relative suitability of different school buildings as evacuation shelters in Cagayan de Oro, the Philippines. Site surveys were carried out to evaluate the scores for each criteria and these were then combined to provide the relative suitabilities.  The paper provides an example methodology that can be applied elsewhere. The findings will be used to help make local recommendations.
