Difference Between Planning and Sequencing/Scheduling

In the example, planning consists of:

• Selection of orders from a large pool of orders, and
• Assigning the selected orders to a plant, P1 or P2, and
• To a week, 40 or 41

The planning process is not concerned with the detailed schedule within a week for a plant.

The detailed sequencing and scheduling process then operates at a plant and weekly level.

• Consider the orders assigned to plant P1 and week 40, and
• Ensure that demand and supply chain constraints are satisfied
• Apply the plant level rules and constraints
• To derive the schedule for P1 – W40

Continue scheduling plant P1 and week 41. After completing plant P1 then schedule plant P2, in a similar manner.
