MASTER PRODUCTION

SCHEDULING
MEANING

Master production schedule (MPS) sets the quantity of


each end item (finished product) to be completed in each
time period (week ,month or quarter) of the short range
planning horizon. MPS are developed by reviewing
market forecasts ,custom orders, inventory levels and
capacity information regularly.

The MPS is a plan for future production of end items over


a short planning horizon that usually spans from a week
to several months. It is important link between
marketing and production.
FUNCTIONS OF MPS
Translating aggregate plans into specific end items
Evaluating alternative schedules
Generating material requirement
Generating capacity requirement
Facilitating information processing
Maintaining valid priorities
Utilizing capacities effectively
1 Translating aggregate plans : This plan translates the
specific no of end products to be produced in specific time
period.the MPS represents a manufacturing plan of what the
firm intends to produce and not the forecast of what the firm
hope to produce

2 Evaluating alternative schedules : MPS is made on trial


and error basis.MPS can be done by simulation using
computers. Detailed material and capacity required are then
derived from the firm MPS.

3 Generating material requirement : The MPS providing


for purchasing and manufacturing the necessary items in
sufficient time to meet the final assembly dates specified, based
on the mps of the end product.
4 Generating capacity requirements: MPS fulfill the
capacity requirements of labour and equipment capacities etc.

5 Facilitating information processing: by controlling the


workloads on work centre, the MPS determines the delivery
schedules for end products both for make to stock and made to
orders items.

6 Maintaining valid priorities: MPS maintaining the


priorities for various jobs. When customers change their
orders or material get scrapped sometimes MPS need to be
changed automatically so as the main priorities are set first
always
7 Utilizing capacity facilities: by specifying the end items
requirements over a time period, the MPS establishes the load
and utilization parameters for labour and equipments.
