ARIS SIMULATOR - How to make instances disappear after a certain dynamic/static waiting time?

Instances only "disappear" if their process folders leave the simulation model. So in your case you'd have to model an XOR rule which leads to an end event. Routing process folders to this end event might be tricky. Perhaps you could combine two loops where one checks if a call center employee is available for receiving the call and one which checks how many times the loop has been run through.  The first can be done with a so-called capacity resource and the second with an ERM attribute. Unfortunately it is not possible to refer to waiting times of a process folder directly in such loops.

While this is not the solution that i'm looking for it probably is the best way to tackle this issue. Thank you for your reply Ralf

Hello again Ralf,

How can i add a ERM attribute to my simulation model in ARIS Business Architect 7.1? I'm sure this is a simple issue but i'm fresh new to this field. If you could redirect me in the right way i would be extremely grateful.

"ERM attribute" is the type of object you have to add. There are different symbols you can use to add an object with this type to an EPC, e.g. "D attribute (ERM)".

Setting an ERM attribute can be done with a "has as output" connection at a function and querying its value with an "is compared to" connection at an event after an XOR rule. The modeling specifics are explained in the ARIS help. You should be able to find it by searching for "ERM attribute".
