Línea de trabajo

Start with set_intervention_ach(), generate_setting_intervention_switches(), and calculate_efficacy_from_ach(); the issue says these currently store and read a single intervention. Review the ACH framework introduced in #142 and compare the indexing approach in malariasimulation’s R/mda_parameters.R. Done means a simulation can use multiple interventions per setting, with indexing, coverage behavior, joint coverage, and parameter naming resolved.

Descripción

Work in progress on branch `multiple-interventions'.

The ACH intervention framework (added in #142) currently supports one intervention per setting (workplace, school, leisure, household, or joint). Generalising it to several interventions in a single simulation raises the points below, collected from review of #142.

Points to address
  • Single intervention stored as a length-1 list. set_intervention_ach() wraps the intervention in list(), and downstream code reads interventions[[1]] (e.g. $coverage in generate_setting_intervention_switches(), and in calculate_efficacy_from_ach()). Calling set_intervention_ach() twice for the same setting overwrites the first intervention rather than adding to it.
  • Indexing interventions. Interventions need a way to be identified and looked up. Options: key them by the name from make_intervention(), or use a user-assigned index, as in malariasimulation: https://github.com/mrc-ide/malariasimulation/blob/master/R/mda_parameters.R
  • Coverage across interventions. Decide whether coverage of multiple interventions is clumped (same locations covered) or independent.
  • Joint coverage. intervention_joint_coverage is taken from a single intervention; check it behaves correctly once there is more than one.
  • Parameter naming. The intervention_<setting>_<param> convention may not scale to several interventions. One option is aqi_intervention_<setting>_<param>; this needs revisiting as part of this work.

From Tom: "In malariasimulation, where multiple interventions of a similar type are used the user assigns them an index which then helps the internal code work through this kind of issue (see https://github.com/mrc-ide/malariasimulation/blob/master/R/mda_parameters.R if interested). Here we have the intervention name from make_intervention which feels like it should be a useful way to resolve the multiple intervention issue."
