In ARIS Business Simulator 7.2.5, the static wait time that must elapse before a function is processed. Various distributions can be applied but that only changes the time. However, in many long-lasting functions there are waiting slots of varying length and distribution along the start of the processing time and the last active processing of the same folder. What would be an efficient way to simulate such functions without breaking them down?
I'm not sure I correctly understand the description of the real-world problem you are trying to model. If I'm not mistaken you mean that a function has multiple waiting and processing phases, e.g. [waiting -> processing -> waiting -> processing].
Simulation only supports the fixed sequence [waiting -> orienting -> processing] where each time can only occur once. An interruption of orientation or processing times can only happen during runtime if a resource goes off schedule.
So I'm sorry to say that the only way for supporting your use case would really be to split the function into multiple parts. (At least I don't have a better idea.) You could do this by assigning an EPC to the function which contains the function's details. This way you'd still have a single function in your main EPC.
Thank you Ralf! Yes, you understood correctly. And yes this is what I did - break up the functions.
One more question: why the sequence is waiting->orientation->processing? I mainly find cases where the sequence is: orientation->processing->waiting. So, if the waiting slots is to much to ask, how about just choosing where to apply the static wait time - first or last.
