摘要

An operation performance generation unit 81 detects either that a subject has entered a predefined operation site or that the subject has exited said operation site, and generates operation performance in which identification information of the subject has been associated with the date and time of the detection thereof and the operation site. An event information generation unit 82 combines a plurality of instances of the operation performance which has been generated for each of the operation sites, determines an event which has been carried out with regard to the subject, and generates event information which represents details of said event. On the basis of the event information, a trace information generation unit 83 generates trace information which denotes either an occurrence of or a change in the subject in a manufacturing process. On the basis of the event information and the trace information, a lead time computation unit 84 computes a lead time for each instance of the trace information.
