F. Campolongo et R. Braddock, The use of graph theory in the sensitivity analysis of the model output: asecond order screening method, RELIAB ENG, 64(1), 1999, pp. 1-12
Sensitivity analysis screening methods aim to isolate the most important fa
ctors in experiments involving a large number of significant factors and in
teractions.
This paper extends the one-factor-at-a-time screening method proposed by Mo
rris. The new method, in addition to the 'overall' sensitivity measures alr
eady provided by the traditional Morris method, offers estimates of the two
-factor interaction effects. The number of model evaluations required is O(
k(2)), where k is the number of model input factors.
The efficient sampling strategy in the parameter space is based on concepts
of graph theory and on the solution of the 'handcuffed prisoner problem' (
