Estimated time between consequences

The estimated time between consequences (ETBC) is the time between unexpected consequences or failures when inspections and preventive maintenance are performed on the asset. APM calculates the residual risk using this value.

Avoidance savings

APM calculates the avoidance savings using: • Downtime costs • Downtime per occurrence costs • Failure costs • Consequence costs • Cost of multiple failures • Secondary damage costs APM uses the time period specified in feasibility settings to arrive at the savings per period.

Maintenance efficiency index

APM calculates the index based on the costs of proposed tasks and the avoidance savings.

Maintenance efficiency index

APM calculates the maintenance efficiency index (MEI) based on the costs of proposed tasks and the avoidance savings. Depending on the MEI threshold, the cost of the proposed tasks is either justified or not justified.

Accept no scheduled maintenance result

On MTA2 and RCM2 failure modes, if the primary proposed task is not justified, you have the option of selecting Accept no scheduled maintenance result. When you click Update Action Plans, the primary action plan’s task type is set to “No Scheduled Maintenance”. Any existing secondary action plans are deleted.

Override result

If the proposed tasks are not economically justified but still necessary, for example, because of regulatory requirements, the result of the evaluation is overridden.
