<p><P>PROBLEM TO BE SOLVED: To provide an operation analysis system capable of attaining a significant improvement in efficiency of operation analysis. <P>SOLUTION: Trace data for one cycle designated as a reference cycle is extracted as a reference cycle pattern from each of a plurality of trace data showing the respective traces of a plurality of parts of a worker who repeatedly performs a predetermined operation. Based on the length of the reference cycle and the reference cycle pattern extracted from each trace data, start times and end times of a plurality of time-series sections are detected from each trace data, and whether each section is a similar section similar to the reference cycle pattern or a non-similar section not similar to the reference cycle pattern is determined based on the trace data within the section concerned and the similarity with the reference cycle pattern. Trace data having the largest number of similar sections is selected as reference trace data from the plurality of trace data, and information including the start times and end times of similar section/non-similar section in the reference trace data is stored. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
