Table 6 Computation times using the meta-model or full model chain

From: Meta-modeling of a simulation chain for urban air quality

Computational times
Meta-model simulation Traffic emissions Compute \({\hat{\alpha }}^{lin}({\mathbf {p}}_m)\) Compute \({\hat{\alpha }}^{AQ}({\mathbf {p}}_m)\) Total CPU
 Initialize meta-model chain \({24\,\text {min}}\)
 Emulating \(\alpha ^{AQ}({\mathbf {p}}_m)\) \(0.05\,\text {s}\) \(0.006\,\text {s}\) \(0.02\,\text {s}\) \({0.076\,\text { s}}\)
Full model simulation Traffic emissions Compute \(c({\mathbf {p}}_m)\) Total CPU
 Simulation of \(c({\mathbf {p}}_m)\) \(117\,\text {min}\) \(23\,\text {min}\) \({140\, \text {min}}\)
