Sensitivity analyses for return rate 𝜑. (a) The aggregated susceptibles in 𝑃₁ and 𝑃₂ regarding the simulation time steps with different 𝜑. The embedded graph is a partial enlargement. (b) The aggregated infectives in 𝑃₁ and 𝑃₂ with respect to the simulation time steps. (c) The variation of the FPT_40% and SSteps(0) for 𝜏. For both of the subpopulations, 𝑁=1000000, 𝜌=0.6, and 𝜏=0.0006. All the results have been averaged 100 times.
