In one embodiment, a product distribution management system includes a product management center. The product management center includes a management device to receive product security data on a product from a distribution site and a product management database to store the data received from the distribution site for use in a product authentication process. The data includes product identification information and security information used to authenticate the product.

Distribution management method and system

A RFID tag structure determining the authenticity of an article, and an information processing system for reading RFID tags, enable authenticity determinations of articles using read only RFID tags. A plurality of RFID tags, each holding tag information inside ROM (read-only memory) and responding to tag information via a radio wave received from a reader, are designed to have a service identifier which designates a common utilization goal for which the same value is set, and service data which sets different values for the respective RFID tags, as tag information. By dividing the data structure of a RFID tag having a read-only memory into a service identifier, which is common to a certain product, and sequential data for managing individual products, it is possible to confirm that an article is authentic by simply confirming the service identifier.

RFID tag, and RFID tag-related determining device and method, and management system and method

A method and apparatus for processing a knowledge which divides a knowledge base into at least two knowledge portions, that is, rule groups so as to permit the rule groups to be processed independently of one another, and selects, as a portion to be processed, only a corresponding divided knowledge portion based on characteristics of knowledge required for a knowledge processing in a scheduling problem which includes a large number of planning data to be processed and a plurality of restricting conditions, thereby enabling a highly efficient and high speed scheduling.
