Scheduling Maintenance Plan with Multiple Items

[ioneke]

We have a scenario where for multiple maintenance items in one strategy plan, the plan date of future calls is calculated based on the last completion date of previous called orders. The scheduling parameters are 100% in Shift factors and Completion requirement flagged.

Is it possible that the scheduling takes as reference the first order completion date instead of the last one?

Thanks!

Hi Jon,

Upon curiosity, why you want to set the call date based on the First Order, even though multiple Items will generate at different times.

Also, Instead of using multiple Items, you can use Object List in one Maintenance item.

There is no standard solution for your requirement, it should be done with the help of technical person, but this will be a challenge.

Considering your example: Doing Maintenance which is not reached the time frame will incur more cost. During reliability analysis they will prefer to optimize the strategy.

Hi Terence, thanks for your answer.

Their purpose, for compliance reasons, is that an object is always maintained before the time frame is reached.

The standard with multiple items is setting the calls based on the completion of the Last Order which will result in future call being planned later than the cycle period itself. In example below Order1 completed the 03-Mar-2017 and next call planned on the 17-Dec-2017, which is >6MON. This is not compliant for them.

The items have different task lists and cycles (eg. Item1 6M and Item2 6MON 1YR) so the object list is not an option I guess.

Then the only option if we don't want to do any custom change to the standard might be that they use single item per plan.

Hi Jon,

If the Maintenance Items have different Task list and Packages assigned, then it is recommended to use different maintenance plans.

When you are scheduling the plan, based on the Strategy and Packages you have assigned in the Task list, all the packages will be called in the maintenance header. So some of the packages will coincide and affect your planning.

Hi Jon,

Pay attention to your Maintenance Plan scheduling parameters. Date determination, call control parameter, and scheduling indicator. Call Horizon and completion requirement (F1 on the two for further assistance).

Thank you.

Hello,

If you set "Completion requirement" indicator, the system only generates the next order once the preceding order has been technically completed. Therefore your scenario doesn't work, in my opinion.

If you want to schedule plan with start day from completion of first order and then don't take into account completion date of the last order you should:

1. Unmark Completion requirement flag

2. Reschedule manually plan (with starting date = completion date of the first order) when the first order will be completed

Hi Yauheni, thanks for your reply. Your proposal might work for this specific maintenance plan, but we would like this logic to apply to all our plans with multiple items. If not possible, then we will suggest business to use one item per plan.

I would like to explain our scenario with an example if someone has any suggestion:

MItem1 (6M) - Completion date Order1: 03-Mar-2017

MItem2 (6M) - Completion date Order2: 17-Jun-2017

Planned dates after next schedule:

MItem1 and MItem2: 17-Dec-2017 while we would like 03-Sep-2017

Thanks again and kind regards.
