 Single-line Planning

Purpose

You can execute Model Mix Planning for an individual line or for a simple line network with sequentially organized lines. Planning may be carried out as follows, for example:

  • In the long-term horizon you want to achieve a 100% line load and thus create cumulated planned orders on a period level.

  • In the medium-term horizon you want to create a provisional sequence and thus take all quantity restrictions into consideration.

  • In the short-term horizon you plan the final sequence taking all restrictions and customers’ preferred dates into account.

Prerequisites

  • You have created the iPPE data in the DI System, transferred it to APO and have completed the master data in APO. See also: Maintaining Master Data

  • In Customizing for Model Mix Planning , you have created a procedure package by assigning the procedure. In the procedure package, for example, you could enter the genetic algorithm for the short-term planning horizon, the prioritized equal distribution for the medium-term planning horizon and the percentage smoothing for the long-term planning horizon. For more information on the possible settings in the procedure package, see also: Rules for Creating a Procedure Package .

Process Flow

The following diagram displays a possible planning run with the three procedures mentioned above delivered by SAP as standard:

  1. The system determines the products manufactured on the predefined line / predefined line network and their orders and requirements. In a first step, the short-term horizon is processed – here you have defined the genetic algorithm. The system calculates the exact order sequence for the planned orders with lot size 1.

  2. In a second step (medium-term horizon), the existing period packages are deleted in the planning run and new planned orders are created with lot size 1. Using the prioritized equal distribution, the system calculates a provisional order sequence.

  3. In the long-term horizon, the system creates period packages for the existing requirements. Using the percentage smoothing procedure, the system achieves a 100% utilization of the lines per period.
