Creates the integer program associated with the CHW placement problem

This function combined the different rasters and shapefiles needed to create the optimisation program

CreateCHWplacement(
  population.raster,
  friction.raster,
  shp,
  name,
  buffer,
  radius,
  capacity.name = "MSPP",
  access.raster,
  popurb.raster,
  max.treat.per.CHW.urban = 2500,
  max.treat.per.CHW.rural = 1000,
  max.CHW.per.pixel,
  is.inside = FALSE,
  filepath
)

Arguments

population.raster

raster map containing population densities

friction.raster

raster map containing friction surface

shp

shapefile of the area of interest

name

name (character) of the MPS file

buffer

buffer around current HF

radius

dimension of the radius around the point (same dimension as T.GC, e.g minutes)

capacity.name

name (character) given to the capacity definition (for folder naming purposes)

access.raster

raster map containing the distance to HF layer

popurb.raster

raster map containing the urban population layer (urban pixels show the population in the pixel and the rural pixels are NA). Can be created with DefineUrban.

max.treat.per.CHW.urban

max number of people per CHW in urban areas

max.treat.per.CHW.rural

max number of people per CHW in rural areas

max.CHW.per.pixel

maximum number of CHW that can be placed on the same pixel

is.inside

whether CHW are placed inside the buffer (if FALSE, they are placed outside)

filepath

directory where to store the MPS file

Value

a MPS file containing the optimisation program
