Furthermore, when the name of any production equipment (e.g., the second process machine) is tapped in the window of the overall graph 51, another window opens and displays a graph of the cycle time fluctuation transition of the production equipment. Hereinafter, this graph is referred to as a cycle time graph. The cycle time graph 53 shown in FIG. 6 is a graph generated and displayed based on the cycle time storage table 45, and displays the history of the cycle time fluctuation transition in a line graph with the cycle time for each cycle on the vertical axis and the time since the production equipment started operating on the horizontal axis. Furthermore, by referring to the error log table 43, dots 54a to 54c indicating the time of error occurrence are plotted and displayed on the cycle time graph 53. The vertical axis positions of the dots 54a to 54c represent the stop time (the number of seconds of the error stop time) associated with the occurrence of an error. In addition, the production equipment 11 to 14 are each equipped with a camera capable of capturing video, and a video is captured when an error occurs. Then, when one of the dots 54a to 54c that indicate an error displayed on the cycle time graph 53 is tapped to select it, a separate window opens as shown in the upper right of Figure 6, and a video 55 is played back and displayed that captures the state of the production equipment from a specified time before the error selected by the dot occurred (about 10 seconds) to a specified time after the error occurred (about 10 seconds to several tens of seconds).
