What is the best way to model a bundler machine? I need to combine 4 bags and I have a rate of 18 bundles per min on the bundler. I first used a combiner with the process time set to 1/18 but then it became a bottleneck because I think it does the process time after I have the 4 bags. I changed the combiner process time to 0 and added a processor right after to handle the process time. This seem to work but I can't get decent utilization statistics because it shows idle as the 4 bags are collecting.
