Time in the simulations

Implementation in MultiMalModPy

🔍 For a detailed overview of how each model handles time, refer to the Time description under malaria models.

In MultiMalModPy, the user can specify the following time related parameters:

  • start_year
  • end_year
  • model-specific burn-in
    • emod_burnin
    • malariasimulation_burnin
    • openmalaria_burnin
  • openmalaria_survey_step

Example from setup_sim.py:

start_year = 2000
end_year = 2005
emod_burnin = 110
malariasimulation_burnin = 100
openmalaria_survey_step = '5d'

From those values, the burnin period is calculated automatically.
EMOD allows to serialize simulations after the burnin period and before the monitoring period, as described in model_specificities.

NOTE:

In OpenMalaria, surveys track events since the last survey and capture the current state at the survey’s start (e.g., the number of patent hosts).

  • The minimum survey interval is 5 days.
  • Only one survey interval can be specified per scenario.
