Description |
|
esriNALAPTMinimizeWeightedImpedance |
Chooses N facilities that will minimize the sum of weighted costs between the facilities and demand points (PMedian). |
|
esriNALAPTMaximizeCoverage |
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 |
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 |
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 |
Chooses N facilities that will maximize the market share of weighted demand points assuming the presence of competitor facilities. Uses a Huff model. |
|
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. |
Remarks
This enumeration 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.
