Probability of Failure Table

Description: Returns a table containing the probability of failure values based on a range of mission end times.

Field Format: [TblProb(Source Number)(Start Time; End Time; Time Increment)]

• Source Number is the associated data source number.
• Start time is the first mission time for which a probability of failure value will be returned.
• End time is the last mission time for which a probability of failure value will be returned.
• Time Increment is the value by which the time will increase.

Remarks:

• The Source Number is selected from the Data Source Index drop-down list.

• The Start Time value must be greater than or equal to 0.
• The End Time value should be greater than or equal to the Start Time value.
• The Time Increment value determines how many rows the table will contain between the start time and end time values and it must be greater than or equal to 0. For example, if the Start Time value is 10, the End Time value is 100 and the Increment value is 10, then the table will have rows for each 10 hour increment from 10 and 100.

Example:

• [TblProb(1)(10;100;10)]
