Processing device and method for making arrangements for parts used in products

A part arrangement processing device comprising:

• first storage means for storing a first parts list indicating a hierarchical composition of parts;
• recomposition means for recomposing the composition of said parts in said first parts list, to create a second parts list;
• second storage means for storing said second parts list;
• and
• data link processing means for establishing a correspondence between the part numbers of parts in said first parts list and the part numbers of corresponding parts in said second parts list.

A processing method for making arrangements for parts composing a product, comprising the steps of:

• creating a design parts list indicating necessary parts in accordance with the results of design in a product design;
• creating a production parts list indicating parts for arrangements for production, in accordance with said design parts list, in a product manufacturing;
• storing said design parts list and said production parts list;
• recomposing a hierarchical relationship among said parts in said production parts list;
• and
• establishing a correspondence between the numbers of parts, in said production parts list, subjected to recomposition and the numbers of corresponding parts, in said design parts list, whereby exchange of part data, between said design section and said production section, is facilitated, even after the recomposition of parts has been performed.
