Methods for developing modular product families contain a lot of information and data that are not always consistent. Consistent data modeling enables simple changes across all affected tools while developing modular product families. Redundant information can be identified and eliminated, and networking between different data is enabled. Inconsistency in variant management is analyzed and addressed with a data model that supports consistency at different hierarchical levels. The data model is modeled with the Cameo Systems Modeler in SysML and is used in a case study for a Design for Variety and modularization with DSM on a vacuum cleaner robot.enConference PaperOther
