pystra.ddo.CostBenefitModel#

class CostBenefitModel(benefit_rate, interest_rate, service_life, construction_cost, failure_cost)[source]#

Cost-benefit objective for a reliability design study.

Methods

`annualized_safety_cost`	Return the JCSS annualized safety cost for a design point.
`consequence`	Return the failure consequence cost for a design value.
`construction`	Return the construction or safety cost for a design value.
`evaluate`	Return results with cost-benefit objective columns.
`objective`	Return the net present value objective for a design point.
`present_value_factor`	Return the present value factor for this model.

present_value_factor()[source]#

construction(design)[source]#

Return the construction or safety cost for a design value.

consequence(design)[source]#

Return the failure consequence cost for a design value.

objective(design, failure_probability)[source]#

Return the net present value objective for a design point.

annualized_safety_cost(design, failure_probability, replacement_cost=None)[source]#

Return the JCSS annualized safety cost for a design point.

evaluate(results, design)[source]#

Return results with cost-benefit objective columns.
