Feedlot
A continuous time discrete event simulation of a cattle feedlot, written in C++.
This prototype is a demonstration project for rapid construction of complex epidemiological simulations. It is a command-line program which produces timelines for spread of FMDV within feedlots of up to 100,000 cattle, separated into separate pens.
- Individual disease progress follows susceptible, latent, infected, and recovered states as described by Mardones, et al.
- Spread of FMDV among individuals within a pen is modeled with an exact equivalent to frequency-dependent SEIR, with a user-specified hazard rate for infection.
- Spread from a pen to neighboring pens is also frequency-dependent where there is fenceline contact.
- As an example of more complicated types of disease spread, a pen rider can carry infection to neighboring pens.
