2. Compile the process sequences for a group of
2.
representative products using information from your
route sheets or process charts.
Calculate the volume of parts required per period.
Determine the number of parts per standard load For example if you handle parts on factory carts,
calculate the partsper cart.
Calculate the flow volume:
No. of parts per period ÷ Parts per load
