Master scheduling subsystem

OVERVIEW:
The Reins of your Manufacturing System

Scheduling production to meet demand and factory capacity.
The MFG Master Scheduling subsystem provides accurate, complete, and timely information to help you achieve your business objectives more effectively - even as changes occur in your markets and production schedules. Rough-cut capacity planning lets you simulate loads on critical resources to swiftly pinpoint potential capacity problems. There is a multi-level planning facility for multiple options forecasting. And it has a flexible reporting and query capability to help you compare actual and forecast performance, examine critical resources and master scheduled parts, and determine whether the schedule is feasible.

Only by knowing how well production continues to meet demand over time can you maintain the master schedule as a viable input to your MRP.



You invest not only your experience but massive amounts of time to develop realistic master schedules based on sales forecasts, plant capacity, financial constraints, and your company's objectives. But only by knowing how well production continues to match demand, as weeks and months go by, can you maintain the master schedule as a viable input to Material Requirements Planning.

A company's master schedule clearly defines the sales and production objectives management intends to achieve, based on such factors as sales forecasts, new product plans, manufacturing capacity, and financial constraints. The Master Scheduling subsystem provides accurate, complete, and timely information to help you achieve your business objectives more effectively - even as unforeseeable and possibly major changes occur in your markets and production facilities throughout the year. It allows for continuous master scheduling to help:

  • Smooth production
  • Lower costs
  • Shorten lead times, and
  • Speed shipments.

Along with keeping tabs on how well actual sales are meeting the forecasts and how work orders compare to scheduled production, this subsystem provides information which allows you to determine whether the master schedule is feasible or needs modifying.

Driving the MRP subsystem.
As the vehicle which communicates the company game plan to the MRP subsystem, the Master Schedule in effect drives the Material Requirements Plan. Since significant company resources are devoted to implementing the plans, management must allot significant attention and care to the master scheduling function.

Simplifying multiple options forecasting.
A large variety of product options make forecasting every possible combination difficult. To solve the problem, the Master Scheduling Subsystem provides a multi-level planning facility. Using a planning bill of material, it combines major subassemblies and options into single planning units. Through the Material Requirements Planning Subsystem, the correct demand for each part or subassembly is derived automatically - based on the proportionate use of each part.

Detailed MDS and MPS records.
The Master Scheduling subsystem reflects the anticipated external demand from the market for the various company products through the Master Demand Schedule (MDS) and management's internal production plan to satisfy that demand through the Master Production Schedule (MPS). Coordination of these two types of schedules ensures that the MPS (together with starting on-hand plus any open orders) can support the MDS within current capacity constraints. Various combinations of MDS and MPS records also impact the MRP explosion process.

Rough-cut capacity planning.
Since the Master Schedule is the starting point from which MRP determines all detailed production schedules, it is important that it be achievable within current resource or capacity constraints. An overstated schedule can actually reduce a plant's output by confusing real needs with unrealistic priorities. To help avoid overstated master production schedules - and to identify potentially critical capacity problems - the Master Scheduling subsystem provides rough-cut capacity planning reports. From the Master Schedule Analysis Report, you can quickly know if - and where - the master schedule may need modifying.

Performance vs. Forecast.
This is where the Master Scheduling subsystem delivers some of its most valuable assistance: keeping tabs on how well actual sales are meeting forecast, and how work orders compare to scheduled production. The subsystem actually consumes the master schedules as sales orders are created and shipments are released. One of the reports which shows consumption of the master schedule is an ideal guide for use in tracking the forecast. Another report delineates the master schedule as a comparison of the forecast to planned production, current inventory and open orders. It balances requirements against planned production, displays projected inventory balances over time, and produces the rough-cut capacity plan.

Flexible reporting and query capability.
The Master Scheduling subsystem allows you to generate analysis or planning reports and query on information relating to master scheduled parts or critical resources. In addition, you can produce reports which serve as guides for use in tracking the forecast and in determining whether the master schedule is feasible or needs modification.
