SEARCH ENGINE TO IMPROVE PRODUCT RECALL TRACEABILITY ACTIVITIES

摘要

The present invention provides an improved method of handling product recall activities through traceability. One embodiment of the present invention involves gathering data in a multi-layered database architecture containing supply, process, test, and customer layers. The data is supplied to a traceability module which contains a search engine to link and access the data. The search engine enables a search by part number, lot number, serial number, time stamp, and date/time frame. A traceability analysis is generated from the search, allowing failure analysis of the data. This analysis is performed through an event list over the entire supply, manufacturing, and customer data, facilitating backward and forward traceability of parts and components of the parts. This failure analysis further facilitates automatic response such as automatic warning and automatic recall to manufacturers and customers.
