工业自动化系统和集成产品数据表示和交换第44部分：集成通用资源：产品结构配置

ISO 10303-44 specifies the integrated resource constructs for Product structure configuration. The following are within the scope of ISO 10303-44: the relationships among the components and assemblies of products; the relationships among products and their components as made by modification of other products; EXAMPLE 1 The machining of a product from another product is an example of a modification. the description of a product as defined by customer needs; the dependencies among specifications of a product in order to represent possible product variations to present to a customer; the management of the structure for configuration of assemblies and components as planned for manufacture; the decomposition of a product to support different product life cycle activities; EXAMPLE 2 An organization maintains one bill-of-material structure for a product that enumerates the quantity of each component used in each assembly, and a second bill-of-material that decomposes a product with multiple assemblies into the individual components. See annex Examples for more examples of different product structure reports that are supported. multiple versions of a single product that are equivalent with respect to form, fit, and function.
