Abstract:
A manufacturing information system for controlling the quality of components received from component suppliers and incorporated into products manufactured by a product manufacturer, said system comprising:a means for receiving a plurality of component identifiers for identifying component lot data records for a plurality of components received from at least one component supplier, each component identifier for identifying a component lot data record for a sub-set of the plurality of components; a plurality of product identifiers for identifying a plurality of products manufactured by said product manufacturer; a data warehouse for storing the product identifiers and the component identifiers; a relation means for relating the component identifiers of components incorporated into said products with the product identifiers for products in which the plurality of components are included; a means for determining a sub-set of the product identifiers, the sub-set of product identifiers identifying a sub-set of the products which have a variation in performance; and an analytical tool for correlating at least one of the component identifiers with the designated sub-set of product identifiers thereby identifying the component lot data record identified by the at least one component identifier as a possible cause of the variation in performance.
