Scheduling by time operation

When a scheduling is associated to an inspection, the expiry date of the test is calculated in the following way:

• If the inspection has never been done: the expiry date is the date of the creation of the inspection.

• if the inspection result is completed and there is already an existing expiry date, the following cases could verify.

  Defining:

  • the current date as the date of the test

  • first recurring date as the first occurrence date according to scheduling

  • second recurring date as the second occurrence date according to scheduling

  • interval_1 = (first recurring date) – (current date)

  • interval_2 = (second recurring date) - (first recurring date)

  the two cases are:

• interval_1 < 50% of interval_2, the new expiry date is set to second recurring date

• interval_1 => 50% of interval_2, the new expiry date is set to first recurring date

In the following table, some other examples of how the scheduling works.

If a scheduling is linked to a working calendar, the Expiry date of the inspection is calculated considering the working and non-working days set in the calendar.

The scheduling linked to a By part inspection is not affected by NOK results. The new expiry date is calculated starting from the execution date.
