<p>PURPOSE:To properly grasp the operation state of a system by counting the operation times of plural events which occurs at the same time, storing them by event numbers, and calculating the rates of the operation times to the total operation time from the operation times and displaying them. CONSTITUTION:Once operation is started, its time is given to an operation time counting device 300, which calculates the cumulative time of a state lasting up to now each time the operation state changes. Then, the operation time is accumulated in an operation time storage device 301 as an increment in the operation corresponding to the number of operators during the time from a certain time to a certain other time and when an operator starts operation again at the other time, the difference between this time and the previously obtained time is calculated as an operation time and accumulated in the storage device 301 as an increment in operation time. An operation time rate calculating device 302 obtains the total simulation time and calculates the rates of the operation times, and an operation time rate display device 303 displays the operator operation time rates by the operator operation numbers.</p> |
