class ParallelSystem(children, name=None)[source]#

A system that fails when all child components or subsystems fail.

The equivalent limit-state function is the maximum child limit-state value.

Methods

`as_limit_state`	Return the composed system as a PySTRA `LimitState`.
`component_failure_masks`	Return failure masks for each leaf component.
`component_values`	Evaluate all leaf component limit states.
`evaluate`	Evaluate the equivalent scalar system limit state.
`failure_mask`	Return a boolean mask where the system is failed.
`get_limit_state`	Return the composed system as a PySTRA `LimitState`.
`iter_components`	Yield all leaf components in the system.

as_limit_state()#

Return the composed system as a PySTRA LimitState.

component_failure_masks(**kwargs)#

Return failure masks for each leaf component.

component_values(**kwargs)#

Evaluate all leaf component limit states.

Returns:: Mapping component names to their evaluated limit-state values.
Return type:: dict[str, ndarray]
Raises:: ValueError – If duplicate component names would make the mapping ambiguous.

property components: tuple[Component, ...]#: Flat tuple of all leaf components in the system.

evaluate(**kwargs)#

Evaluate the equivalent scalar system limit state.

failure_mask(**kwargs)#

Return a boolean mask where the system is failed.

get_limit_state()#

Return the composed system as a PySTRA LimitState.

This legacy-style alias mirrors the existing PySTRA getter naming.

iter_components()#

Yield all leaf components in the system.
