## Summary

Enumeration specifying the decay function type for the LocationAllocation analysis. The decay function type, or impedance transformation, sets the equation for transforming the network cost between facilities and demand points. This property, together with the decayFunctionParameterValue property (β), specifies how significantly the network impedance between facilities and demand points influences the solver's choice of facilities.

## Properties

Property | Explanation | Data Type |

Linear (Read Only) | The cost is equal to the network impedance. This is a good choice when locating facilities such as warehouses where the goal is to minimize overall transportation cost. cost With this option, the decayFunctionParameterValue is always set to 1, since changing the value of a parameter on a linear transformation doesn't affect the solver's results. | Object |

Power (Read Only) | The cost is equal to the network impedance raised to a power. The cost is exaggerated to make locations that are further away appear even less attractive. The exaggeration is not as severe as with exponential decay. This is a good choice when locating large retail facilities, such as car dealerships. cost | Object |

Exponential (Read Only) | The cost has an exponential relationship to the network impedance. The cost is exaggerated to make locations that are further away appear even less attractive. The exaggeration is more severe than with the power option. This is a good choice when locating smaller retail facilities, such as grocery stores. cost Exponential transformations are commonly used in conjunction with an impedance cutoff. | Object |
