Elimination is used to eliminate maintenance plan lines in Maintenance Plan tab that are planned to fall due at approximately the same period in time when several PM triggering mechanisms are used, such as a calendar trigger and a condition based trigger. For example, if the PM falls due based on a condition based trigger today, it is not necessary to generate a work order for a calendar that falls due tomorrow. In other words, the percentage denotes at which maintenance yield a maintenance plan line should be eliminated when another PM trigger will fall due first. This field can have a value between 50 and 100.

If the calculated elimination value of a line is larger than the Elimination At (%) value specified in the General tab of Separate PM Action, this line is eliminated. These eliminated lines will be displayed as not generatable in Maintenance Plan tab.

First two generatable lines are taken as the base for the calculation

Elimination At (%) = 85



Calculation of Elimination value of line 3

Elimination Value = ((Jan 6 – Jan 1)/ (Feb 1 – Jan 1)) * 100 = 16.13 < 85

Therefore 3rd line is not eliminated.



Calculation of Elimination value of line 4

Elimination Value = ((Feb 1 – Jan 6)/ (Feb 5 – Jan 6)) * 100 = 86.7 > 85

Therefore 4th line is eliminated.



Calculation of Elimination value of line 5

As line 4 is already eliminated, 2nd and 3rd lines are used as base for the calculation of elimination value of line 5,

Elimination Value = ((Feb 1 – Jan 6)/ (March 1 – Jan 6) )* 100 = 48.1 < 85

Therefore 5th line is not eliminated.
