Is there any example available that shows the PI AF hierarchy created on basis of Processes running in a refinery or batch running plant ?
We generally see/create AF hierarchy on the basis of equipment, location, etc. But I want create a AF hierarchy on the basis of processes seen in a refinery such as cracking unit, distillation unit. Generally in an O&G organisation, there are experts for furnace, steam, cracking etc who handle operations across multiple location and are process oriented.
Hope you can get what I seek.
