MODEL FOR MANAGING CHANGES IN PRODUCT STRUCTURE OF PRODUCT

摘要

PROBLEM TO BE SOLVED: To manage and present information about changes in a product structure of a product.SOLUTION: A product management system comprises a model and a data manager. The model includes design data for a product structure of a product. The model also includes a primary hierarchical organization of master objects, some secondary hierarchical organizations of version objects, and a change context organization of each master object. The master objects include element objects and appearance objects. The secondary hierarchical organizations include element version objects and appearance version objects. The change context organization includes a group of variant objects and a group of branch instance objects. The data manager manages changes in design data of a design structure in each design branch independently of other design branches using the model so that products can be manufactured with higher efficiency using the model.SELECTED DRAWING: Figure 1
