Problem types for the Location-Allocation solver

Remarks

The values within this enumeration are used to indicate the type of problem to be solved by the INALocationAllocationSolver.

The esriNALocationAllocationProblemType has the following values:

• esriNALAPTMinimizeWeightedImpedance - Locates N facilities such that it minimizes the sum of weighted Impedance of the demand point locations. Also called the P-Median problem type.
• esriNALAPTMaximizeCoverage - Maximizes the coverage of demand locations by a given number of facilities and a specified covering distance or impedance. Also called the maxcover problem type.
• esriNALAPTMaximizeCoverageMinimizedFacilities - Computes the minimum number of facilities needed to maximize the coverage of demand locations within a specified covering impedance.
• esriNALAPTMaximizeAttendance - Chooses N facilities to maximize the demand point weight allocated to the facilities assuming that the allocated demand weight decreases with increased network distance.
• esriNALAPTMaximizeMarketShare - Chooses N facilities that will maximize the market share of weighted demand points assuming the presence of competitor facilities. Uses a Huff model or a gravity model also known as spatial interaction.
• esriNALAPTTargetMarketShare - 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 or a gravity model also known as spatial interaction.
