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 \(c({\mathbf {p}}_m)\) | \(117\,\text {min}\) | – | \(23\,\text {min}\) | \({140\, \text {min}}\) |
