Master Production Schedule (MPS) is a critical tool for manufacturers.

It helps ensure that the right products are made at the right time and in the right quantities.

This post will answer questions on MPS, its functions, and its benefits. Keep reading to learn more about it and how it can benefit your organization.

Definition of Master Production Schedule

Master Production Schedule

Master Production, as the name suggests, decides what products need manufacturing and the accurate time to manufacture that product.

Master Production Scheduling (MPS) is a process in manufacturing to decide which products to produce and how much quantity is required to meet the requirement in a given interval of time.

It can be used in any industry where a good deal of production is necessary, such as manufacturing, construction, and logistics.

There are many different versions of it, but all achieve the same goal: creating a plan that allocates resources to deliver products or services on time and at the lowest possible cost.

This production planning tool helps companies manage their finite resources to produce the greatest possible output. As a result, companies using MPS report improved efficiency, reduced waste, and increased customer satisfaction.

Master Production Plan

Bill of Materials (BOM) and Material Requirements Planning (MRP) are the two crucial aspects of it.

The Bill of Materials BOM then identifies the raw materials required to produce finishing goods.

Importance of Master Production Schedule(MPS)

MPS is an integral part of an Enterprise Resource Planning system. It provides the most effective planning functionality by extracting the actual demand and supply data to deliver precise production plans.

These plans assist manufacturers in quickly achieving their production goals and minimize the cost incurred on the procurement.

While performing calculations of operating expenses, it pays special heed to the manufacturing capacity of the production plant.

Automatic initiation of Material Resource Planning management process and generation of the purchase order takes place soon after the analysis and the approval of the production orders.

Aside from all these implications, it acts as a protective barrier against shortages, unexpected scheduling snafus, and inefficient allocation of resources.

Inputs to MPS

Inputs of MPS

Following are the list of inputs,

  • Forecast demands
  • Known orders
  • Key capacity constraints
  • Inventory level
  • Spares demand
  • Safety stock requirements
  • Exhibition promotion requirements
  • R & D demands
  • Sister plant demand

Different methedologies for Master Production Scheduling

The Master Production Schedule needs to devise a final plan for manufacturing using all the currently available resources.

If the MPS emphasizes too many items, then the plan proposed by MPS does not apply to the manufacturers.

Apart from that, the production capacity suffers if the plan proposed by MPS isn’t detailed enough.

As a general rule of thumb, master scheduling is only applicable in the particular case where the smallest number of product alternatives are available.

Methodologies for MPS

Make to Stock Environments

In this specialized scenario, a minimal quantity of items is assembled to form a more significant number of components.

In this scenario, the Master Production schedule would be the schedule of finishing valuable items.

Make-to-Order or Build-to-Order Environments

In this case, various finishing goods are made from minimal raw materials. One of the great examples of this case is the manufacturing process of automobile vehicles.

The main aim of the Master Production Schedule in the Make-to-Order environment would be the periodic arrangement of the actual customer orders.

Assemble-to-Order Environments

Assemble-to-order environments utilize raw materials to produce subassemblies and the essential components effectively.

These components and sub-assemblies work in harmony to form various finishing goods.

In this specialized environment, the Master Production schedule should emphasize at the subassembly level.

MPS in each of these scenarios emphasize the specific area.

Benefits of Master Production Schedule

  • It provides an effective and most reliable communication conduit with the sales team to facilitate the planning process.
  • Effectively reduce the time incurred in the manufacturing process throughout the year.
  • It acts as an effective barrier against the shortage of raw material and any unexpected mishap.
  • Make necessary adjustments to address the fluctuation in demands while reducing the waste properly.
  • It smartly managed the cost incurred on manufacturing on behalf of the business owner and made the most precise calculation about the raw material requirements.
  • It enhances the overall efficiency in the location of production resources.
  • It acts as a foundation to construct, improve, and track the sales forecast.
  • It helps the organization’s account department reach income and expenses by providing account statements like profit & loss statements and the balance sheets.
  • It helps in the calculation of inventory levels.

Functions of Master Production Scheduling (MPS)

The automated software system of Master Production Scheduling possesses too many attributes.

Before implementing the automated system of Master Production Scheduling, it is generally regarded as a good practice to analyze the critical aspects of this computerized system that facilitate production.

Here are the critical functionalities of the Master Production Scheduling automated system.

Transforming Plans

This specific portion of the software speculates the amount of material, labor, and specialized equipment required to meet the manufacturing goal.

Provide Alternative Production Routes

The automated system of Master Production Scheduling produces a trial and error schedule that gives an alternative route to accomplish the production.

That would tackle any unexpected mishap that would arise within the completion of production.

Utilization of Available Resources

Automated software of Master Production Scheduling establishes the relationship between the load and utilization for the machinery and equipment deployed in the manufacturing process.

That allows for the best utilization of all the available resources and a more efficient production flow.

Establish Capacity Requirement

Automated software of Master Production Scheduling facilitates capacity planning through establishing proper capacity requirements.

Master Production Scheduling facilitates the manufacturers to obtain the proper knowledge about the requirement of capacity.

Aid in Information Processing

MPS determines the best appropriate time for delivery. It consistently coordinates with the various management information systems.

Master Production Schedule Example

Master Production Schedule (MPS) transforms the business plans into the intelligent management of the impact of seasonality, promotion, and fluctuating demand.

Here is a typical real-life example,

A pump manufacturer sells ready-to-made products. To successfully manage the sales the pump manufacturer needs to assemble these products before shipping them within 48 hours after taking orders.

The time required for the completion of the production process is one day. Although numerous components and subassemblies are still necessary for the successful manufacturing of the pump, these subassemblies and internal components enhance the production time from 2 days to 2 months.

To successfully manufacture a pump within 48 hours, the pump manufacturer must access all the components required to manufacture finishing products.

How is production planning different from the master production schedule?

Production planning is the phase that comes before the master production schedule. Production planning defines the higher production level and tiny details.
Production planning determines how many products should be produced. But MPS defines and decides the number of products made in a given time interval.


Master Production Schedule is generally regarded as the heart of manufacturing Enterprise Resource Planning because it correlated manufacturing and planning.

The MPS management system has been extensively used as a helpful tool for the most precise calculation of resources required to fulfill production plans.

It helps to identify production bottlenecks and potential problems. -MPS can help with forecasting, capacity planning, inventory management, order fulfillment/production schedule.

With the MPS in place, it is easier for a company to predict demand more accurately, which will reduce on-hand inventories. This also improves customer service since customers are not waiting on products that may be out of stock or unavailable at any given moment.
