Modify process time based on number of operators

Hi,

I have a situation where a processor needs (at max) 2 operators to work on it. The process time changes with the number of operators working.

If 1 operator works, there is some process time for the processor. When the 2nd operator comes, whatever processing time is left on the processor at that instant, that needs to be halved.

Ex. Processor processing time = 50 min (for 1 operator)
Op. 2 comes after 10 min.
Time left = 40 min.
New process time required = 40/2 = 20 min.

Need some help on the above.

Thanks.

There are different approaches to doing this. One of them (experimental) is here.

I used a different approach once. On the OnResourceAvailable of the second operator I checked if another process needed an operator (had several Processors). On each Processor kept the EndProcesTime in a label. Created a task sequence (travel, message, utilize) for the operator. On the message I destroyed the event on the Processor and created a new one based on the new (remaining) process time. You have to be sure then that the second operator gets in time to the processor otherwise it would be no use calling for the operator.

Hi,

"On the message I destroyed the event on the Processor and created a new one based on the new (remaining) process time."

How do you get at what time the operator is coming to the new processor?

Thanks Jason. Can you provide some explanation or some simpler model on the same. Basically, I just need the time when the 2nd operator is coming to help the first one. If I get that, I can reduce the time as per my requirements.

Look at the processor label called "processdurations" as a 'Label Table'. In the right column enter the duration the process would take if that number of operators was available from the start of, and throughout the process. If the maximum number of operators you can have is two, just resize the table to 2 rows. That's it! The time adjustment is calculated and applied automatically.
