Master production schedule
Master production schedule (MPS) - is a detailed plan of the production broken down by specific time intervals (usually days, weeks or months).
Structure and application
It allows to describe the expected production volume of particular product. MPS diagram allow to specify the gross demand in the MRP algorithm, which is necessary to plan the amount of necessary materials.
MPS is customarily presented in the form of a table where the columns are substituted for previously defined time intervals and rows for the number of available lines of products, number of pieces supplied and the anticipated demand for the product.
Objectives of master production schedule
The two main objectives of the master production scheduling are:
- Securing material for final assembly, which is being carried out based on specific customer needs. To be able to perform specific order in time desired by the client semi-products and materials must be prepared according to MPS.
- Ability to assess the ability to take orders. Based on ongoing production and awaiting execution of orders we can calculate if and how much we can offer to our customers. MPS is method to transform customer orders into production orders spread over time.
Due to the fact that MPS is used for further planning requirements for the materials. It is always created for individual products never for entire product groups.
