I'm creating a model based around the CNA (certified nurse assistant) tasks and I'd like to create a call bell interrupt. I have data of how often and the most frequent times that they get call bells going off and I want to incorporate it into the model somehow. I saw that there is an Interrupt tool, but it looks like its only used for machines, is it possible to use it based on the beds? I'd like the specific CNA assigned to go to that room and it'll be a process time of triangular(2,3,20). Or would it be better to use a Global Process? If I use the Global Process, how can I have call bells go off for different rooms?
