Based on the SIR model, but with additions of:
- Delays
- Deaths
- Variable transmission rate, dependent from government action U
State Variables:
- S = Subsceptible
- I = Infective
- R = Removed
- D = Death
- Pd = Probability of death
- Tr = Transmision rate
constant parameters:
- a = number of days for the infected to show sintoms
- b = number of days for the infected to begin infecting
- maxtr = maximum tr, normally before quarantine
- mintr = minimum tr, normally when severe quarantine
- rr = recovery rate
- maxdr = maximum death rate, normally when sanitary system are collapsed
- mindr = minimum death rate, normally when the sanitary system is not collapsed.
- Icol = Infected rate to collapse the sanitary system.
- inf_test = rate of tested from infected.
