When a certain disease model should be used in scenario, the initial conditions for the isease have to be specified. The following components in STEM enable the user to do so. The Disease Initializer component provides the combined functionality of the Infector and Inoculator components. For initialization from an external file the External Data Source Disease Initializer must be used.
Infector
Please see Creating a STEM Scenario to see an example of how infectors are used. Infectors can be used to set initial conditions when you want to start a simulation with a specific number or percentage of people in the infectious state. The infector, at simulation start, takes the specified number from the Susceptible state and moves them to the infectious state.
Inoculator
There is currently no documentation about inoculators.
Disease Initializer
To create an initializer for a specific disease, the user has to right click on the disease and select "Create new Initializer".
Since initializers also work for diseases with multiple populations, the population to initialize has to be selected. For the selected population the absolute number or percentage of individuals for all compartments can be specified. At last the user has to select a location for the initializer. If for example France is selected, any region in France is initialized with the chosen values. The new initializer will show up under the "Decorators" folder in the Project explorer. You can drag the initializer right into a scenario.
External Data Source Disease Initializer
To create an initializer for a specific disease, the user has to right click on the disease and select "Create new External Data Initializer".
Since initializers also work for diseases with multiple populations, the population to initialize has to be selected. For the selected population the folder containing the log files for the specific disease and population has to be entered. Finally one must specify the number of the row to be used. The new initializer will show up under the "Decorators" folder in the Project explorer. You can drag the initializer right into a scenario.
