1. Calculate the gross demand of all n-level items (finished products, parts, accessories, blanks) according to the time period

2. Determine the net demand N(t) at level n for period t

3. Determine n-level t-period planned order storage P(t) based on net demand

4. Calculate the planned inventory of all n-layer parts in period t

5. According to the t period planned order storage, determine the t-L period planned order quantity.

6. If a certain component is produced in the company and an order is placed in cycle t, that is, assembly begins in cycle t, its underlying components must be provided in that cycle.
