CreateCHWplacement_SCIP: Creation of MPS file and txt.Script

In SwissTPH/CHWplacement: What the Package Does (One Line, Title Case)

Creation of MPS file and txt.Script

Description

This function executes the CLSCP problem to find optimal locations (Current & Storbeck) using the lpsolveAPI package for integer programming. Relies on the functions CHW_CreatProgScript_SCIP and PrepareRasterFiles (see functions_CLSCP)

Usage

CreateCHWplacement_SCIP(
  population.raster,
  friction.raster,
  access.raster,
  popurb.raster,
  shp,
  filepath,
  name,
  buffer,
  radius,
  capacity.name = "MSPP",
  max.treat.per.CHW.urban = 2500,
  max.treat.per.CHW.rural = 1000,
  max.CHW.per.pixel,
  is.inside = FALSE,
  dualitygap = 1,
  relativegap = F,
  SCIP_version = "7.0.3"
)

Arguments

population.raster	raster map containing population densities
friction.raster	raster map containing friction surface
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.
shp	shapefile of the area of interest
filepath	directory where to store the MPS file
name	(character) name 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)
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)
dualitygap	condition of suboptimality acceptance for the solver: give an upper bounds of the difference with an hypothetical optimal solution
relativegap	if true -> |primal-dual|/MIN(|dual|,|primal|) else |primal-dual| (more interpretable but less accurate)
SCIP_version	version of the SCIP shell downloaded

Value

a MPS file containing the optimisation program and txt script to run it in SCIP shell
