The master production schedule is a short-term production plan that spans a few weeks to several months. It sets the quantity of each finished product to be produced in each time period. The MPS provides information on planned production quantities and timing. It serves as the basis for resource planning, customer delivery commitments, balancing sales and operations, and achieving strategic goals. Master production scheduling techniques include maintaining positive inventory levels as a buffer for potential production or demand fluctuations.
2. What is master production schedule.
• The master production schedule is a plan for
future production of end items over a short –
range planning horizon that usually spans
from a few weeks to several months .
The mps sets the quantity
of each end item(finished product) to be
produced in each time period (week/month or
quarter) of the short-range planning horizon.
3. •The MPS gives the information about
the quantities and timing of the planned
production of a product.
•Start with Aggregate plan
(Aggregate Sales & Ops Plan)
4. Provides basis for:
•Making good use of manufacturing
resources
•Making customer delivery promises
•Resolving tradeoffs between sales
and manufacturing
•Attaining strategic objectives in the
sales and operations plan
5. Master Production Scheduling
Techniques
• Available = inventory position at end of week
• = starting inventory + MPS – forecast
• Plan to have positive inventory level
– Buffer in case production below plan
– Or demand higher than anticipated

weak 1 weak 2 weak3 weak4 weak5
Demand forecast(in units) 300 200 100 500 800
customer order (committed) 350 100 50 300 400
initial inventory in period weak=0 500
net inventory before mps 150 -50 850 350 -450
master production schedule(mps) 1000 1000
projected on hand inventory 150 950 850 350 550
The rule of thumb is that whenever the net inventory before the MPS becomes negative a new lot of items is schedule for production in the MPS of that time period.
