Part chain management in an aftermarket services industry
A part chain management system and method for generating chain sequences for parts in the aftermarket services industry is disclosed. Data on various parts and their substitutes is obtained from an engineering data management (EDM) team and translated into pair wise substitutional relationships represented in a known part substitutional relationship network. The system and method derive a part chain representation from known part substitutional relationships and inferences determined therefrom. The system and method can refine or filter the part chain representation based on rules such as business relationships. The system and method analyzes inferred part substitutional relationships for conflicts, which are either resolved automatically using conflict resolution rules or are referred for manual resolution. Following conflict resolution, the inferred links are finalized and used along with known links to generate a final part substitutional relationship network. Planning/inventory management tools can utilize the final network to plan and manage part substitutions.
