I am interested in mathematically describing as well as formalising a manufacturing plant so that other people in the engineering field understand how the system works. I am not from the engineering field, and so I don't know what the typical standards for this type of task are.
Suppose the manufacturing plant consists of three work units: A warehouse, a transport system and a processing station. The materials are transported from the warehouse to the processing station, where they are processed and then stored again. This process repeats itself indefinitely. What is the best and most professional way how an engineer would describe this system?
So far, I have described the process textually, but I shall only explain it by mathematical formulas or figures. Are there various specifications or guidelines in the engineering environment? I don't know what a good starting point is.
