System, method, program for assigning virtual attribute to product, and system, method, and program for tracing cause of phenomenon occurring in product

摘要

A system for tracing a cause of a phenomenon occurring in products produced in a production process chain is provided. The system is provided with a storage unit for storing a virtual attribute in association with corresponding second products, a receiving unit for receiving information for specifying third products in which a phenomenon occurs, a correlation calculation unit for calculating a correlation coefficient between the third products specified by the information for specifying the third products and the group of the second products having a common virtual attribute, for every kind of second products used in the third products, and a cause identification unit for identifying the second products belonging to the kind of the second products for which a maximum correlation coefficient is calculated as the cause of the phenomenon.
