Patent ID: 7242992

Claim:
A system for assisting findings of problems by revealing the problems existing and concealed in parts supplies chains, wherein parts produced in a production unit are supplied to and used in a subsequent production unit to produce higher level parts, the higher level parts produced in the subsequent production unit are supplied to and used in a further subsequent production unit to produce even higher level parts, and the sequences are repeatedly executed at multiple steps until final parts are produced in a final part production unit and the final parts are supplied to a final product production unit for producing final products, the system comprising: a means for storing product-parts lists of multi-stages and parts supplies information; wherein the product-parts lists of multi-stages comprises a final product and a list of adjoining lower level parts constituting the final product (a list of first parts), and the lower level part and a list of even lower level parts constituting the lower level parts (a list of second parts constituting the first part, a list of third parts constituting the second part, etc.), wherein the product-parts lists of multi-stages includes linking information for connecting lists in sequences at multi-stages, and wherein the parts supplies information corresponds to each of the lower level parts included in the product-parts lists of multi-stages, the parts supplies information including at least one item selected out of the traveling distance of the part, the defect rate during the production of the part, the cost of the part, and the lead time of the part, and a means for storing reference vales concerning to parts supplies information, a means for graphically displaying the product-parts lists of multi-stages and the parts supplies information corresponding to each of the parts, wherein the product-parts list includes a production unit of the lower level part listed in the list for each lower level part, and the product-parts list is stored for each production unit wherein the graphic display displays the parts supplies chains and parts and parts supplies information, and wherein the parts supply information are displayed in a different mode depending on whether the reference values have been fulfilled or have not been fulfilled.
