| Summary: | The experience feedback on a crisis that hit a city is frequently used as a
"recollection" tool. To capitalize information about an experience feedback
from the cities that have been affected by a natural hazard, the authors
propose in this study a functional model to model scenarios of
city crises. In this model, the city, considered as a complex system, was modelled
using a functional analysis method. Based on such modelling, two risk
analysis methods (Failure Mode and Effect Analysis and Event Tree Method)
were deployed and adjusted. Lastly, a qualitative reasoning model was
used for the scenario modelling of the urban crisis. By functional
modelling performed on components of the cities, the objective of this model is
to replicate the behaviour of a city affected by a crisis, highlighting the
sequences of failure and non-failure modes that have operated during the
crisis. This model constitutes a means of understanding the functional
behaviour in a crisis of cities and capitalization of the experience feedback of
the cities affected by crisis. Such functional modelling was deployed in a
case study. |
