Dear Aris Commnity,
I´m writing my master thesis with ARIS Archtitect 9 and try to simulate an model with EPC. In this context the following problem/ question appeared:
I ´ve assigned a technical resource to a function. In my case, the technical resource is a machine. The machine (technical resource) requires 5 machines to execute the function. The function has a processing time of 5 minutes. If now the process is run through once (process instance =1) under the assumption that only the described function above exists, then the processing time of the process is equal to 5 minutes and the processing time of the machine (5 machines * 5 minutes) is equal to 25 minutes.
My question is, can the processing time of the technical resource be integrated into the simulation-based evaluation of the processing time of the process? So that the simulation result of the processing time of the process would be 25 minutes and not 5 minutes
I would be very grateful for your help!
Nice regards

When you specify the 'Required capacity' attribute at the connection between a technical resource and a function, it means that this number of resources is required to jointly carry out the function once. So for the accumulated processing time of the process this one execution is relevant, in your case five minutes. In the resource statistics the processing time is accumulated for all the resources jointly working on this one function execution. Since it requires five resources in your case, that's why you get 25 minutes of accumulated processing time for the resource.
An accumulated processing time of 25 minutes for the function would require it to be carried out five times, not just once. If you want to have parallel execution of the function, you'd have to model five occurrence copies of the function which are fed from a diverging AND rule and then have flows to a converging AND rule. A sequential execution could be modeled with a loop that is controlled by an ERM attribute. Or you simply maintain a processing time of 25 minutes for the function and require only one machine for the execution. That'd be similar to a sequential execution.
