Limit number of proccesses per day/shift on a processor

Hello everybody!

How are you?? My question is that I am trying to code a restriccion that limits the number of operations per day on a processor. In other words, I want to have a processor that only does 2 processes per day or shift (there is only 1 shift per day, so I don't mind). But I can't think in any logic to make that restriccion works. Any suggestions?

I tried a pull strategy with pullitem() only if the variable with the content on that day on that processor (I keep the date in another variable to check) is not higher than 2, but in some point stops working well :(

If I don't put any processes limit per day, it works perfectly the pullitem logic... D: so I am missing something -.-

Thanks!

Hi Ana,

you can try some variation of the attached model. In this one, the processor will process 2 jobs in 1 hour, randomly spacing the jobs within the hour.

Hope it helps!

You choose randomly three values by statistical distributions.
You sum the values to get a base of 100%.
Then you compute the percentage of each randomly chosen value to the base of 100%.
This percentage value multiplied by your time interval value gives you the first and second arrival time at your processor.

You must delay the entry time to your processor by another processor or simply in a Process Flow activity
