Use FRACAS Operating Time records to calculate operational time
|
When selected (default), operating time is based on records in the FRACAS Operating Time table. Thus, the checkboxes beneath this property are available.
• If end date is blank, use today’s date. When selected (default), the day on which the calculation is run is used as the end date. When cleared, operating time records with blank end dates are ignored.
• Multiply operating time by the Configuration quantity. When selected (default), the operating time is multiplied by the configuration quantity.
|
Continuous operation
|
When selected, operating time is assumed to be continuous (24 hours a day), and all Operating Time records are ignored. When calculating overall MTBF, the following properties are available so that you can graph MTBF over a specified time period.
• Start date. The date on which continuous operation began. The default is the current date. If you change the start date but not the end date, the overall MTBF until the present time is computed.
• End date. The date on which continuous operation ended. The default is the current date. If you change the end date, the date that you specify becomes the new default.
