The approximate length of time that it takes to complete the task. APM uses this information when a task is placed on a schedule.You can enter an estimated duration, or APM can calculate the duration based on the trade, tool, or time-based service requirements. To enter a duration, clear the Calculate option.
The system calculates the task’s estimated duration. APM sets the task’s estimated duration to the trade, tool, or service requirement with the longest total duration (Lag time plus the Required for time).
• One mechanic: 4 hours, 0 lag (4 hours total)
• One electrician: 2 hours, 3 hour lag (5 hours total)
• One mechanic: 2 hours, 5 hour lag (7 hours total)Alternatively, clear the Calculate option to enter the estimated duration.
• All indicators on the task – All of the standard task’s indicators are included in the list of indicators to read whenever the task is triggered. This option is handy for repair tasks, for example.
• Indicators due to be collected before the task’s next expected occurrence – Only indicators that are due to be collected before the next expected triggering of the task are included in the list of indicators to read. This option is handy when the next expected triggering of the task is determined by the standard task’s expected frequency.
• Indicators due to be collected in the collection horizon period – Only indicators with frequencies within the selected collection horizon are included. If you select this option, specify the collection horizon.
• Exception based inspection – Only readings that are mandatory, for indicators where the previous reading resulted in an alarm, or for indicators where the alarm on the previous reading was acknowledged with “monitor” or a work document and the document is not closed.
• Due date is based on the task’s indicators – The task’s due date is set to the earliest collection due date of its indicators. The date is recalculated whenever an indicator is added to the task, an indicator is removed from the task, an indicator’s collection date changes, or an indicator’s collection status changes to Active or Inactive
• Due date is based on the task’s frequency – The task’s due date is calculated by adding the frequency duration to the date when the task was last triggered
To restrict triggering of the standard task, select Only triggered when the asset and site have the following statuses. Then select the statuses for which triggering is valid.
