Master production schedule 1

Master production schedule

A master production schedule (MPS) is a plan for production, staffing, inventory, etc.[1]

It is usually linked to

manufacturing where the plan indicates when and how much of each product will be demanded.[2]

This plan

quantifies significant processes, parts, and other resources in order to optimize production, to identify bottlenecks,

and to anticipate needs and completed goods. Since an MPS drives much factory activity, its accuracy and viability

dramatically affect profitability. Typical MPS's are created by software with user tweaking.

Due to software limitations, but especially the intense work required by the "master production schedulers",

schedules do not include every aspect of production, but only key elements that have proven their control effectivity,

such as forecast demand, production costs, inventory costs, lead time, working hours, capacity, inventory levels,

available storage, and parts supply. The choice of what to model varies among companies and factories. The MPS is

a statement of what the company expects to produce and purchase (i.e. quantity to be produced, staffing levels, dates,

available to promise, projected balance).[1]

[3]

The MPS translates the business plan, including forecast demand, into a production plan using planned orders in a

true multi-level optional component scheduling environment. Using MPS helps avoid shortages, costly expediting,last minute scheduling, and inefficient allocation of resources. Working with MPS allows businesses to consolidate

planned parts, produce master schedules and forecasts for any level of the Bill of Material (BOM) for any type of

part.

How an MPS works

By using several variables as inputs the MPS will generate a set of outputs used for decision making. Inputs may

include forecast demand, production costs, inventory costs, customer orders, inventory levels, supply, lot size,

production lead time, and capacity. Inputs may be automatically generated by an ERP system that links a sales

department with a production department. For instance, when the sales department records a sale, the forecast

demand may be automatically shifted to meet the new demand. Inputs may also be inputted manually from forecasts

that have also been calculated manually. Outputs may include amounts to be produced, staffing levels, quantity

available to promise, and projected available balance. Outputs may be used to create a Material Requirements

Planning (MRP) schedule.

A master production schedule may be necessary for organizations to synchronize their operations and become more

efficient. An effective MPS ultimately will:

Give production, planning, purchasing, and management the information to plan and control manufacturing[3]

Tie overall business planning and forecasting to detail operations[3]

Enable marketing to make legitimate delivery commitments to warehouses and customers
