8. Qualitative assessment based on Indicators
ADVANCED RESEARCH WORKSHOP
Azores, 28th June 2016
Qualitative assessment based on Indicators
Two ways of filling in the table;
(a) Indices/characteristics rely on subjective assessments (qualitative or semi-qualitative approach).
(b) Indicators that quantify system attributes (e.g., reliability), which are assumed to be related to the resilience.
What are the most important indicators?
How much does any indicator explain the resilience (weight)?
How overlapped are the indicators?

ADVANCED RESEARCH WORKSHOP

Qualitative assessment based on Indicators
The STRUCTURED EXPERT JUDGMENT ELICITATION FOR DEPENDENCE MODELLING is used to determine the dependence and overlapping between resilience and any possible indices, obtaining the structure of the dependence relations between variables.
This approach can be used to identify the most relevant indicators to be considered when assessing those descriptors of traffic networks.
This methodology will allow quantitative approaches, rather than the so common qualitative or semi-qualitative methods.
