Set Processor Breakdown

Hi !

I want to set breakdown time in Processor ,Processor needs to break for lunch time for 60 minutes per day ,break for refueling time for 15 minutes per day ,break for maintenance for 180 minutes for every 15 days ,and break for small maintenance in every 2-5 days by spending 20 minutes per time .I run the processor 720 minutes (12 hours) per day ,from 6:00 AM till 6:00 PM. How can I achieve that ? I have tried several time to do that in breakdown tap ,but I don’t know how to set the value since the setting constraints I want is plenty and complicated.

Here is my sample model compare-modelp.fsm

FlexSim 19.0.0

Please use the toolbox and therein the Time Table tool. Because you want to set different stop types: lunch, short maintenance, long maintenance you have to edit in the Down and Resume function the Stop ID and the Resume ID. The ID must be in one time table identically, but different to each time table. If you have MTBF / MTTR or stopobject and resumeobject activities to deactivate a time table member, you must assign to them an individual ID, too.

The ID value controls, that the object resumes to the right stop.

For example you set that the short and long maintenance begins at 9 o’clock AM with the same ID. On days when both time tables stop the processor the ID of the short maintenance will resume the long maintenance at same time. You won’t never see a long maintenance in your model occurs.

Please add for each breakdown type an own time table. You can assign the members to the time table, that should use this table. If you have different lunch times in your model you add for each different repeating start time a single time table.

Can you help by giving me an example of an action?

I think what @Jörg Vogel is saying is that you would create an MTBF/MTTR parameter for each of your aforementioned situations. For example, one for lunch times, one for refueling, one for maintenance, etc.

This would be most effective, but you could also find statistical averages for your down time and compile the averages into one MTBF/MTTR parameter.

@Tanner Poulton I tried to set MTBF/MTTR in Up Time and Down Time for lunch break . I run ,and observe what was going in model ,but I don’t see the effect following what I changed. If you can give me example of an action,I will learn how to set ,so I can set all the situation that I mentioned.

Thanks ,

@Jörg Vogel I still can’t figure out what you suggested about “The ID must be in one time table identically,but different to each time table .Kindly please give me an example or explain more.

Thanks,

Try it on your own. Three time tables with the same stop time but different durations. Once with an identical ID number and another time with different ID in down and resume function.

You find the mechanism described in the manual object.stop.
