Integrating MTBF/MTTR Time Tables for Maintenance: Addressing Overlapping Events

[Zayth]

[ FlexSim 23.2.3 ]

Hi, I am building a maintenance model with the tollbox (MTBF MTTR/time tables) but I have a problem with the construction of scheduled maintenance, I am using the time tables for it. The drawback is that the times in the time table and the MTTR repair time intersect, these events occur at the same time, what I want is that when there is an MTTR no event occurs (time tables) and vice versa, when there is scheduled maintenance (time tables) a break down does not occur (MTBF MTTR). Since I am performing calculations in the on break down on repair (MTBFMTTR) and on down on resume (time table) of the toolbox. Or how can I propose a model similar to the one I want to make?

I would greatly appreciate your help.

I think you could work around this using the Breakdowns tab on the MTBF/MTTR table:

Basically, you can make it so only the states you choose contribute to the MTBF time. So the machine won't break down while it's idle or in scheduled_maintenance.

Hi Jordan, thank you very much for helping me.

Now I have a problem when a breakdown is repaired since it intersects with the maintenance scheduled for it. I think I have a solution and it is the following: when a breakdown occurs in the simulation, deactivate the time table and when it returns, activate it again. I don't know the line of code() to trigger said action. It might solve what I want to do.

And the last question is if I can reset up time of the MTBF/MTTR properties when scheduled maintenance is performed.
