Method and computer system for reducing runtimes in material requirements planning

摘要

Method and computer system for reducing the runtime of a material requirements planning run. A computer system is loading a plurality of bills of materials into a data structure (300). It analyses parent-child relationships (310) between components of the plurality of bills of materials in the data structure (300) and sets for each component in the data structure (300) a counter value (CV) that indicates the number of parent components for each component. The counter value (CV) of a specific child component (A2) is decremented when the planning of a parent component (F1, F2) of the specific child component (A2) is completed. The computer system then proceeds with the planning of the specific child component (A2) if the associated counter value (CV) indicates that the planning of all parent components (F1, F2) of the specific child component is completed.
