# Location-Allocation Solver Properties

## Summary

The following properties are supported by the network analyst solver object when working with the location-allocation solver.

## Properties

Property | Explanation | Data Type |

travelDirection (Read Only) | The direction of travel between facilities and demand points when calculating the network costs. This property returns the following keywords: - FACILITY_TO_DEMAND
- DEMAND_TO_FACILITY
| String |

problemType (Read Only) | The location-allocation problem type that will be solved. This property returns the following keywords: - MINIMIZE_IMPEDANCE
- MAXIMIZE_COVERAGE
- MINIMIZE_FACILITIES
- MAXIMIZE_ATTENDANCE
- MAXIMIZE_MARKET_SHARE
- TARGET_MARKET_SHARE
| String |

defaultTargetFacilityCount (Read Only) |
The number of facilities that the solver should locate. | Integer |

defaultCutoff (Read Only) | The maximum impedance at which a demand point can be allocated to a facility. If no cutoff value is specified in the network analysis layer, the property returns an empty string. | Double |

impedanceTransformation (Read Only) | Indicates the equation used by the solver for transforming the network cost between facilities and demand points. This property returns the following keywords: - LINEAR
- POWER
- EXPONENTIAL
| String |

impedanceParameter (Read Only) | The parameter value to the equations specified in the impedance transformation. | Double |

targetMarketShare (Read Only) | The target market share in percentage to solve for when the problem Type property is set to TARGET_MARKET_SHARE | Double |

laLinesShape (Read Only) | The type of line generated by the solver. This property returns the following keywords: - NO_LINES
- STRAIGHT_LINES
| String |
