In traceability system applications, it is required to check relationships between individual articles under management and containers therefor such as container cases or pallets. Since relevant data in each stage of physical distribution is not always registered, the absence of some necessary data may occur to cause inaccurate commodity tracing. To solve this disadvantage, the present invention provides a traceability system capable of complementing information regardless of time-series factors. Even in a situation where a plurality of sets of information (relational data) regarding packing-unpacking relationships between articles and containers, e.g., relationships between commodity products and packing cases, or relationships between packing cases and pallets, are not registered in time-series order, the relational data are complemented in registration to enable complementary estimation from registered information available at the time of reference.
