CalendarEventCoordinator

The CalendarEventCoordinator coordinator class distributes individual-level interventions at a specified time and coverage. See the following JSON example and table, which shows all available parameters for this event coordinator.

Note

Parameters are case-sensitive. For Boolean parameters, set to 1 for true or 0 for false. Minimum, maximum, or default values of “NA” indicate that those values are not applicable for that parameter.

EMOD does not use true defaults; that is, if the dependency relationships indicate that a parameter is required, you must supply a value for it. However, many of the tools used to work with EMOD will use the default values provided below.

JSON format does not permit comments, but you can add “dummy” parameters to add contextual information to your files. Any keys that are not EMOD parameter names will be ignored by the model.

The table below describes all possible parameters with which this class can be configured. The JSON example that follows shows one potential configuration.

Demographic_Coverage

The fraction of individuals in the target demographic that will receive this intervention.

{
    "Demographic_Coverage": 1
}

Distribution_Coverages

array of floats

0

1

0

A vector of floats for the fraction of individuals that will receive this intervention in a CalendarEventCoordinator.

    "Distribution_Times": [
        100,
        200,
        400,
        800,

        0.05,
        0.1,
        0.2,
        1.0
    ]
}

Distribution_Times

array of integers

1

2.14748e+09

0

A vector of integers for simulation times at which distribution of events occurs in a CalendarEventCoordinator.

{
    "Distribution_Times": [
        100,
        200,
        400,
        800,
        1200
    ],
    "Distribution_Coverages": [
        0.01,
        0.05,
        0.1,
        0.2,
        1.0
    ]
}

Intervention_Config

JSON object

NA

NA

NA

The nested JSON of the actual intervention to be distributed by this event coordinator.

{
    "Intervention_Config": {
        "class": "OutbreakIndividual",
        "Incubation_Period_Override": 1,
        "Outbreak_Source": "PrevalenceIncrease"
    }
}

Node_Property_Restrictions

array of JSON objects

NA

NA

NA

A list of the NodeProperty key:value pairs, as defined in the demographics file, that nodes must have to be targeted by the intervention. See NodeProperties and IndividualProperties parameters for more information.

You can specify AND and OR combinations of key:value pairs with this parameter.

The following example restricts the intervention to nodes that are urban and medium risk or rural and low risk.

{
    "Node_Property_Restrictions": [
        {
            "Place": "URBAN",
            "Risk": "MED"
        },
        {
            "Place": "RURAL",
            "Risk": "LOW"
        }
    ]
}

Property_Restrictions

array of JSON objects

NA

NA

NA

A list of the IndividualProperty key:value pairs, as defined in the demographics file, that individuals must have to be targeted by this intervention. See NodeProperties and IndividualProperties parameters for more information.

To specify AND and OR combinations of key:value pairs, use Property_Restrictions_Within_Node. You cannot use both of these parameters in the same event coordinator.

{
    "Property_Restrictions": [
        "Risk:HIGH"
    ]
}

Property_Restrictions_Within_Node

array of JSON objects

NA

NA

NA

A list of the IndividualProperty key:value pairs, as defined in the demographics file, that individuals must have to be targeted by this intervention. See NodeProperties and IndividualProperties parameters for more information.

This parameter allows you to specify AND and OR combinations of key:value pairs. You may specify individual property restrictions using either this parameter or Property_Restrictions, but not both.

The following example restricts the intervention to individuals who are urban and high risk or urban and medium risk.

{
    "Property_Restrictions_Within_Node": [
        {
            "Risk": "HIGH",
            "Geographic": "URBAN"
        },
        {
            "Risk": "MEDIUM",
            "Geographic": "URBAN"
        }
    ]
}

Target_Age_Max

float

0

9.3228e+35

9.3228e+35

    "Target_Demographic": "ExplicitAgeRanges"

{
    "Target_Age_Max": 20,
    "Target_Age_Min": 10,
    "Target_Demographic": "ExplicitAgeRanges"
