The document discusses master production scheduling (MPS) as a critical process in operations management, detailing its role in synchronizing production output with customer orders and market demand. It explains how MPS serves as a bridge between sales and operations planning (S&OP) and highlights key elements such as forecasted demand, booked orders, and available-to-promise (ATP) quantities. Additionally, the document includes graphical representations and examples of calculations related to MPS, illustrating how to determine projected inventory and ATP for specific products.

Planning and Control
 Planning and control – A set of tactical and
execution-level business activities that
includes master scheduling, material
requirements planning, and some form of
production activity control and vendor order
management.

Master Scheduling
 Master Scheduling – A detailed planning process that
tracks production output and matches this output to
actual customer orders.
 Controls the timing and quantity of production for
products or product families.
 Serves as the primary interface point for actual customer
orders.
 Coordinates forecasted demand and actual orders with
production activity.
 Serves as a tool for agreement between marketing and
operations (but at a different level than S&OP).

Master Schedule Record
 Forecasted demand
 Booked orders
 Projected inventory levels
 Production quantities
 Units still available to meet customer needs
(Available to Promise)

Forecasted Demand
vs. Booked Orders
 Forecasted demand – A company’s best
estimate of the demand in any period.
 Booked orders – Confirmed demand for
products
Projected Requirements =
Maximum (Forecasted demand, Booked orders)

Master Production Schedule (MPS)
 Master Production Schedule (MPS) – The
amount of product that will be finished and
available for sale at the beginning of each
week.
 The MPS quantities drive more detailed planning
activities, such as material requirements
planning.

Ending Inventory
• Projected Ending Inventory – Best estimate
of what inventory levels will look like at the
end of each week based on current
information.

Available to Promise (ATP)
 Available to Promise – A field in the master schedule
record that indicates the number of units that are
available for sale each week, given those that have
already been promised to customers.
