Managing Skipped Work Orders and Fixed PMs

By default, the system will not generate another Work Order until the previous Work Order is complete. Only one Work Order per PM is allowed open at a time. You must close the Work Order before the next PM can be generated.

Alternately, you may enable one or more work options explained below to help you manage skipped Work Orders.

Note: While there are solutions to managing skipped Work Orders, agencies who experience this problem frequently may want to reconsider workflow and scheduling.

System default

When the Work Order is completed or closed (Status > 950), the skipped Work Order will generate almost immediately and the Work Order Start Date will be back-dated to the missed Start Next Date.

In this example the PM is set to generate on the first of the month. However, some of the Work Orders are not closed in time and the system is running without any special options enabled. Work Orders are not skipped, they are just generated later and back-dated.

* Work Order Start Date was back-dated because the previous Work Order was not closed on time.

Note: If multiple iterations of the PM were skipped, this process will repeat when each Work Order is closed until the system catches up to the present iteration of the PM.

 

Reset missed starting date

The work option Reset Missed Starting Date prompts the system to set the Start Next Date to the next date in the future that the PM would generate based on its schedule. The PM will not generate any skipped work. The Start Next Date will always be in the future so the number of PM iterations skipped does not matter.

In the example below the PM is set to generate on the first of the month. However, some of the Work Orders are not closed in time and the system is set to reset the schedule. If scheduled dates are skipped they are reset to future dates. However, the PM keeps to its original schedule of only generating Work Orders on the first of the month.

Always generate Work Orders on PM Schedule

The work option Always Generate Work Orders on PM Schedule overrides the system rules that stop Work Orders from being generated when the previous Work Order is still open. This causes all Fixed Schedule PMs to generate even if previous Work Orders were not closed.

In the example below, the PM is set to generate on the first of the month. Because this work option is enabled, the system is set to ignore whether or not the previous Work Order is closed.

Warning: While this work option bypasses the problem of unclosed Work Orders preventing the system from generating new Work Orders, it can also cause Work Orders to pile up since others are not yet completed.

Floating Scheduling

A Floating Schedule generates a Work Order based on the Next End Date. This type of PM schedule will generate with a fixed interval between Work Orders.

For example, you have a PM for an asset to be cleaned once per month. Once the asset is cleaned and the Work Order is closed, no matter the duration of cleaning, the asset does not need to be cleaned again for one month from the end of cleaning. The following diagram shows that the next Work Order is generated one month after the previous Work Order closed no matter the duration of the cleaning work:

Notice that the Start Date for one Work Order is always a month after the End Date for the previous Work Order.

Floating PM related fields

Last End Date

Stores the End Date for the last Work Order generated by the PM. Work Orders will be generated based on the last time the job was completed.

  • Note: This is populated by the system no matter which type of scheduling is used.

End Date Interval

Indicates the number of (date) units between one Work Order ending and the next beginning.

  • Used to calculate the End Next Date.

End Interval Code

Specifies the type of units between Work Orders that the End Date Interval represents (e.g., days, weeks, months, years).

  • Used to calculate the End Next Date.

End Next Date

Marks the next date the PM will generate a Work Order.

  • Calculated automatically when the Last Start Date and Start Date Interval and Start Interval Code are entered.
  • Example: A Work Order is generated on 8/15/2018 and completed on 8/17/2018 which is put in the Last End Date field. The End Date Interval is 1 and the End Interval Code is Years. The system calculates the End Next Date to be 8/17/2019.

Schedule modification

Generating Work Orders ahead of schedule

Floating Schedule PMs can be generated before their End Next Date by populating the Days Ahead field. This helps employees prepare for upcoming work.

floating schedule days ahead

In this example the PM is set to generate 3 Days Ahead of schedule. The PM will generate the next work order on 12/18/2018. The work order's Start Date will be 12/21/2018.

Exclusion Days

The Lucity system can be configured to skip generating a Work Order on a specific day, date or range of dates.

Meter Based Scheduling

A Meter Based Schedule generates a Work Order based on a fixed interval between the previous work's meter reading and a future meter reading rather than dates. For example, you have a vehicle that needs to have the tires rotated every 5,000 miles. That work does not need to be completed again for another 5,000 miles no matter how long it previously took to complete.

Meter Based Scheduling works with:

The following diagram shows that the Work Order is generated 5,000 miles after the previous Work Order closed no matter when the previous Work Order was closed:

meter pm schedule

 

Work Order Due

Work Order Completed

Work Order 1

5000 miles

5,430 miles

Work Order 2

10,430 miles

14,900 miles

Work Order 3

19,900 miles

21,000 miles

Work Order 4

26,000 miles

-

Notice that even though the work was due at one mileage, the vehicle was used for awhile before it was brought in for work, which is why the completed mileage is higher. The miles that the Work Order was finally completed at is used to calculate the miles that the next Work Order should be due.

Note: In the above examples Miles or Odometer could be swapped out for Hours and Hourmeter, or Units and Other Meter.

Generating Work Orders ahead of schedule

Meter Based Scheduled PMs can be generated before they reach their scheduled reading by populating the Odometer Ahead, Hourmeter Ahead or Interval Ahead fields. This helps employees prepare for upcoming work.

In this example the PM is set to generate 100 miles ahead of schedule. The PM will generate the next Work Order when the vehicles Current Odometer > 10430.

Mixed Scheduling (Floating and Meters)

PMs also support using a mixture of a Floating Schedule and a Meter Based Schedule. Therefore the PM will generate work based on the Next End Date or the Next Odometer/Next Hourmeter/Next Other Meter, whichever comes first.

For example, you have a vehicle that requires maintenance every 3 months or 5,000 units, whichever comes first. Once the work is done it does not need to be completed again for another 3 months or 5,000 units. When the work is complete using Mixed Scheduling, both the Date and Meter Based Schedules are updated.

Mixed Scheduling works with:

The following diagram shows that the Work Order is generated based on time passed or meter reading increases.

Work Order History

Between Work Order History

Work Order 1

The work order was generated based on the asset's other meter reaching 5000 units. The work was completed within a week and with only a little additional mileage.

The asset was used steadily over the next 3 months.

Work Order 2

The work order was generated based on reaching 3 months of service. However, that was a busy week and several hundred units were put on the asset after the work order came due and before the work was done.

The rest of the month was very busy and the asset accumulated 5000 units within the next few weeks.

Work Order 3

The work order was generated based on the meter reaching the 5000 unit threshold. However, the maintenance team was too busy to service the asset. The asset was put on light duty for one month and only accrued an additional 1000 units before the work was complete.

The first half of the month was very busy and asset quickly accrued 5000 units.

Work Order 4

The work order was generated based on the meter reaching the 5000 unit threshold. The work was completed within several days.

The asset is used sparingly over the next 3 months.

Work Order 5

The work order was generated based on the asset reaching 3 months of service. The work was completed quickly.
