Patent ID: 7421373

Claim:
An improvement support system for production of products comprising: an input unit; a display; an arithmetic processing unit; and a storage unit, wherein for a product failure to be expected, the storage unit stores analytical data comprising analytical information having information corresponding to “phenomenon” or “influence” and “cause” or “measures” for each of a plurality of failure modes which are classified in view of parts constituting the product or manufacturing processes of the product, and malfunction generation historical data formed based on malfunction contents detected in manufacturing processes of the product in which malfunction information having information corresponding to the “phenomenon” or “influence” of the failure mode in the analytical information is sequentially accumulated, the malfunction generation historical data including a separate ID number for each detected occurrence of product failure, and the arithmetic processing unit being configured to, for each detected occurrence of a product failure, detect a failure mode having information corresponding to the “phenomenon” or “influence” by searching the analytical data, based on information corresponding to the “phenomenon” or “influence” contained in the malfunction information, relate the detected failure mode to the malfunction information, count the total number of malfunctions related to the detected failure mode, and display the contents of the failure mode together with the total number or based on the total number in the display.
