class ResilienceCurves(*, resilience_curves=<factory>)

Bases: object

Class to store the resilience curves for different link types.

Parameters:

resilience_curves (dict[tuple[RoadTypeEnum, tuple[float, float]], list[tuple[float, float]]])

calculate_disruption(link_type, hazard_range)

Calculate the disruption for a given link type and hazard range. It is guaranteed that the duration steps and functionality loss ratio have the same dimensions.

Return type:

float

Parameters:

• link_type (RoadTypeEnum)

• hazard_range (tuple[float, float])

Args:

link_type (RoadTypeEnum): The type of the link. hazard_range (tuple[float, float]): The range of the hazard.

Returns:

float: The calculated disruption.

get_duration_steps(link_type, hazard_range)

Get the duration steps for a given link type and hazard range.

Return type:

list[float]

Parameters:

• link_type (RoadTypeEnum)

• hazard_range (tuple[float, float])

Args:

link_type (RoadTypeEnum): The type of the link. hazard_range (tuple[float, float]): The range of the hazard.

Returns:

list[float]: The duration steps.

get_functionality_loss_ratio(link_type, hazard_range)

Get the functionality loss ratio for a given link type and hazard range.

Return type:

list[float]

Parameters:

• link_type (RoadTypeEnum)

• hazard_range (tuple[float, float])

Args:

link_type (RoadTypeEnum): The type of the link. hazard_range (tuple[float, float]): The range of the hazard.

Returns:

list[float]: The functionality loss ratio.

get_resilience_curve(link_type, hazard_range)

Get the resilience curve for a given link type and hazard range.

Return type:

list[tuple[float, float]] | None

Parameters:

• link_type (RoadTypeEnum)

• hazard_range (tuple[float, float])

Args:

link_type (RoadTypeEnum): The type of the link. hazard_range (tuple[float, float]): The range of the hazard.

Returns:

list[tuple[float, float]]: The resilience curve.

has_resilience_curve(link_type, hazard_range)

Check if a resilience curve exists for a given link type and hazard range.

Return type:

bool

Parameters:

• link_type (RoadTypeEnum)

• hazard_range (tuple[float, float])

Args:

link_type (RoadTypeEnum): The type of the link. hazard_range (tuple[float, float]): The range of the hazard.

Returns:

bool: True if the resilience curve exists.

property ranges: list[tuple[float, float]]

resilience_curves: dict[tuple[RoadTypeEnum, tuple[float, float]], list[tuple[float, float]]]

object_type

alias of ResilienceCurves

read(file_path)

Reads from a given file and converts the data into Any type.

Return type:
