You can prevent the scheduling of duplicate or unnecessary activity definitions in a maintenance plan, which are linked to the same asset condition details in the Assets TSI.

Automatic integration of activity definitions is required if an asset’s or building element’s condition details refer to a survey activity definition with a non-cyclic maintenance regime and an activity definition with a condition-based maintenance regime. The non-cyclic activity definition can affect the schedule of the condition-based activity definitions. Therefore, Planon ProCenter will automatically reschedule these activity definitions.

To understand how survey activity definitions can affect the scheduling of condition-based activity definitions with the same asset condition details, see the following example:

In this example, the first condition–based activity definition was planned 9 months after the most recent survey date. Also, a non-cyclic survey activity definition is added in Maintenance Planner for the same asset after compiling a maintenance plan.

Suppose a survey took place on 1/1/2010 and the maintenance activity that was based on the survey activity definition brings the asset’s condition back to the Condition after maintenance score 1.5. The Condition after maintenance of this activity definition will affect the first scheduled activity of the condition-based activity definition.

Planon ProCenter calculates the time it takes to reach condition 4. Refer to the table displaying the Deterioration > factor in Setting a condition-based schedule for an activity definition.

The factor of the (Required condition) - (Observed condition) =

Deterioration factor (0,875 - 0, 25) = 0,625.

Remaining deterioration period = Deterioration > period * 0,625 = 1, 25 years.

Therefore, after 0, 75 years (after 15 months after 1/1/2010 i.e. 1/11/2012) the first possible condition–based activity is scheduled. This in turn, will reschedule the subsequent maintenance activities.
