series

Aggregate response statistics assuming a series system

parallel

Aggregate response statistics assuming a parallel system

Description

With the system probability/reliability option, statistics for specified response_levels are calculated and reported assuming the response functions combine either in series or parallel to produce a total system response.

For a series system, the system fails when any one component (response) fails. The probability of failure is the complement of the product of the individual response success probabilities.

For a parallel system, the system fails only when all components (responses) fail. The probability of failure is the product of the individual response failure probabilities.
