StandardInterventionDistributionEventCoordinator

The StandardInterventionDistributionEventCoordinator coordinator class distributes an individual-level or node-level intervention to a specified fraction of individuals or nodes within a node set. Recurring campaigns can be created by specifying the number of times distributions should occur and the time between repetitions.

Demographic restrictions such as Demographic_Coverage and Target_Gender do not apply when distributing node-level interventions. The node-level intervention must handle the demographic restrictions.

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.

Parameter	Data type	Minimum	Maximum	Default	Description	Example
Demographic_Coverage	float	0	1	1	The fraction of individuals in the target demographic that will receive this intervention.	{ "Demographic_Coverage": 1 }
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" } ] }
Number_Repetitions	integer	-1	1000	1	The number of times an intervention is given, used with Timesteps_Between_Repetitions.	{ "Event_Coordinator_Config": { "Intervention_Config": { "class": "Outbreak", "Num_Cases": 1 }, "Number_Repetitions": 10, "Timesteps_Between_Repetitions": 50, "class": "StandardInterventionDistributionEventCoordinator" } }
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	The upper end of ages targeted for an intervention, in years. Used when Target_Demographic is set to ExplicitAgeRanges or ExplicitAgeRangesAndGender.	{ "Target_Age_Max": 20, "Target_Age_Min": 10, "Target_Demographic": "ExplicitAgeRanges" }
Target_Age_Min	float	0	3.40282e+38	0	The lower end of ages targeted for an intervention, in years. Used when Target_Demographic is set to ExplicitAgeRanges or ExplicitAgeRangesAndGender.	{ "Target_Age_Max": 20, "Target_Age_Min": 10, "Target_Demographic": "ExplicitAgeRanges" }
Target_Demographic	enum	NA	NA	Everyone	The target demographic group. Possible values are: Everyone ExplicitAgeRanges ExplicitAgeRangesAndGender ExplicitGender ExplicitDiseaseState	{ "Target_Age_Max": 20, "Target_Age_Min": 10, "Target_Demographic": "ExplicitAgeRanges" }
Target_Gender	enum	NA	NA	All	Specifies the gender restriction for the intervention. Possible values are: Male Female All	{ "Target_Gender": "Male" }
Target_Residents_Only	boolean	0	1	0	When set to true (1), the intervention is only distributed to individuals that began the simulation in the node (i.e. those that claim the node as their residence).	{ "Target_Residents_Only": 1 }
Timesteps_Between_Repetitions	integer	-1	10000	-1	The repetition interval.	{ "Timesteps_Between_Repetitions": 50 }
