Comparison of results from different global sensitivity indices

	Average of local sensitivities	Sobol's first order sensitivity	Sobol's total effect sensitivity
8 dominant parameters*	k8, k9, k5, kc1, k3, k1, k-_1, k4	kc1, k12, k3, k13, k9, k24, k10, k-1	kc1, k3, k12, k9, k13, k1, k10, k5
CPU time	24 hours	160 hours	160 hours
Objective function†	3.546	8.364	7.745

* The common parameters identified by all the sensitivity indices were highlighted in bold style and the parameters by any of two different sensitivity indices were underlined.

† Global optimization (Evolutionary Strategy using Stochastic Ranking) was executed with respect to the parameter combination selected by each sensitivity index.
