esriNALocationAllocationProblemType Constants

Problem types for the Location-Allocation solver

Constant Value Description
esriNALAPTMinimizeWeightedImpedance 0 Chooses N facilities that will minimize the sum of weighted costs between the facilities and demand points (PMedian).
esriNALAPTMaximizeCoverage 1 Chooses N facilities that will reach all demand points within a specified cutoff. Once all demand points have been reached the sum of weighted costs between the facilities and demand points will be minimized.
esriNALAPTMaximizeCoverageMinimizeFacilities 2 Chooses the minimum number of facilities necessary to reach all demand points. Solution facilities will minimize the sum of weighted costs between the facilities and demand points.
esriNALAPTMaximizeAttendance 3 Chooses N facilities that will maximize the demand point weight allocated to the facilities assuming that the allocated demand weight decreases with increased network distance.
esriNALAPTMaximizeMarketShare 4 Chooses N facilities that will maximize the market share of weighted demand points assuming the presence of competitor facilities. Uses a Huff model.
esriNALAPTTargetMarketShare 5 Chooses the minimum number of facilities necessary to achieve the target marketshare of weighted demand points assuming the presence of competitor facilities. Uses a Huff model.
