Decomposition Method for Resources (New)

Use

It was previously possible to define decomposition methods for the SNP optimization run in the SNP optimizer profile. Decomposition is used to reduce the runtime and memory requirements of optimization. Decomposition can also enable the optimizer to find a feasible solution in the event of difficult discrete problems.

The decomposition methods available before this release were time decomposition and product decomposition. As of SAP APO 4.0, resource decomposition is also available.

Resource decomposition speeds up the solution process by analyzing the material flow and basic optimizer decisions about production, procurement, transportation, and so on to determine a resource sequence. The optimizer can then create partial problems for the individual resources, which are solved in sequence. The optimizer makes decisions in each of these partial problems to load resources.

It is a particularly good idea to use resource decomposition if the production processes always load the resources in a similar sequence. Resource decomposition does not reduce memory requirements. To reduce memory requirements, you can use time decomposition alongside this decomposition method. You cannot use resource decomposition alongside product decomposition or strict prioritization.
