PROBLEM TO BE SOLVED: To easily grasp and analyze operating electric energy for each product item, by creating a production chart for indicating the run hour of the product item in time series, and by matching the time base of an electric energy fluctuation graph to that of a production chart for display. SOLUTION: The time-series fluctuation measurement data of operating electric energy, for example, in first, second, and third production departments are stored in floppy disks 1A, 1B, and 1C that are used as storage media, respectively. Also, product item data including the product item name, production start time, and production termination time of each production section in the production departments are saved in floppy disks 2A, 2B, and 2C. An FD drive 11 for reading the data in each floppy disk, a storage RAM 12 for storing data and a working RAM 13, respectively, a printer 14 for displaying, and a CPU 10 for controlling each configuration element are provided. |
