It should have a formal master production schedule to help in making informed decision. Consequently, there is a need to upgrade their forecasts, since they are low and their production capacity needs to meet more than 20, bread makers in a week. Similarly, from the projected on hand inventory the company is under promising to its customers because the ending inventories for most weeks are higher than the customer orders. They also have available- to-promise numbers increasing as the customer orders decrease.
When companies produce in the make-to-stock environment, forecast is the most critical factor. The demand must cover the product requirements, but also replacement parts testing, service. When on the other side companies produce in make-to-order environment, production is not started until the customer order arrives.
Nevertheless, raw materials and parts have to be in stock at the time of order. In assemble-to-order similarly to make-to-order, all the components are required when order arrives, therefore earlier planning is required.
Customer Orders - Sum of all customer orders allocated, reserved, unplanned Slots allocated - each of the accepted customer orders takes one slot. Slots reserved - These slots are used by the management. Whenever they're not sure whether order will become firm or not, they use this.
Unplanned slots - These as the name suggests are slots used by unplanned unexpected orders which were not included in the forecast calculations.
Net demand - It's based on forecasts. When within time fence - it's based on the orders. Firm Planned Order - Firm orders are orders which has already been released.
They cannot be changed by the system - each change to firm order requires manual intervention. Firm orders may already be in production. Planned Order - Manufacturing order automatically calculated by the system or manually entered.
Planned Order is calculated using the following formula: Time Fences[ edit ] The first week or two can be frozen - no changes are allowed during this time - this is called time fence. There are different time fences: Forecast time fence - it's a period where only orders are used when calculating Net demand.
Reservation time fence - only firm customer orders can be accepted for allocation during this period MPS time fence - within this time, MPS stay firm.
Available to Promise time fence - no additional orders may be accepted in this period. We can clearly see that there is no demand forecasts for week 1 and 2.
This is the case because these two weeks are inside the time fence where only customer orders are used to calculate Net demand see above. Whether the orders are allocated, reserved or unplanned - all of them are added together and the resulting output is Net demand.
To calculate Net demand outside of time fence, we simply take the maximum of these two: Demand forecast Sum of all customer orders allocated, reserved, unplanned Whichever is greater - it's used in the Net demand.
It should be long enough to avoid problems with scheduling. Typically Planning Horizon should be longer than the cumulative lead time for the item. The accuracy of the MPS decreases the more you deviate from the planning horizon. This is because a short term MPS has actual orders in its Netting whereas further out in the planning horizon the MPS relies almost solely on forecasts.
Below is an example of what a fragment of the MPS table looks like.A Master Production Schedule is the virtually exact same thing as MRP (Material Requirements Planning), the calculations are exactly the same, but there is one distinction. MPS plans items that have “direct” demand, called independent demand.

Master Production Schedule (MPS)  The Master Production Schedule is a detailed Plan of Production. It drives the MRP system by referencing inventory, requirements and bill of materials.

A production schedule template is what you will use to manage your master production schedule. The master production schedule is considered the head of all schedules and provides managers with all the information needed.
