Abstract: The invention creates a number of End Item Configuration lists, each End Item Configuration list including a listing of those custom components and variations of standard components which are utilized for a selected configuration of a complex product. A basic bill of materials is also created including a listing of those standard components utilized for all configurations of the complex product. Thereafter, a relationship is established between a particular End Item Configuration list and a customer contract for the manufacture of a selected configuration of a complex product. Based upon the established relationship, a selected one of the End Item Configuration lists is retrieved and combined with a basic bill of materials to create a complete bill of material utilizing both the End Item Configuration list and the basic bill of materials, which may then be utilized in the manufacture of a particular configuration of a complex product.

Abstract: An attribute-based automated classification and retrieval system for group technology applications using a codeless classification system in which hierarchical classification structures are stored in a classification attribute file and in which searches can be performed at any level in the classification structure. The relationship between entities and classification attributes are kept in an item classification parameters file along with the parameter values associated with each entity-attribute pair. Queries on the data stored in the classification attribute file and item classification parameters file are stored alternately in a plurality of query results files as successive queries are used to narrow the scope of a search.
