FIG. 1 is a block diagram showing the configuration of an operation management apparatus according to one embodiment.

In FIG. 1, reference numeral 1 denotes an operation management device main body;
Is a search unit (search means) for searching for data from the storage unit (storage means) 6, which is a database. In the storage unit 6,
Average failure interval and average repair time data (target value) for each station (processing device) on the line obtained by simulation at the time of line design, and operation data for each station collected via the network line 7 (target value) The number of production, the number of failures, the repair time, etc.) are accumulated. Note that the operation management device main body 1 and the storage unit 6 constitute an operation management device.

Reference numeral 3 denotes a processing unit for performing a predetermined process based on the search result from the search unit 2 and the items input by the input unit (selection means) 4. Items input by the input unit 4 include a search period, a display type (content), and the like. Reference numeral 5 denotes a display unit (display means) for displaying the data processed by the processing unit 3.

In the above configuration, the processing unit 3 constitutes calculation means for calculating the average failure interval and the average repair time based on the operation data retrieved during the retrieval period input by the input unit 4.

Next, a display operation by the operation management apparatus having the above configuration will be described with reference to FIGS.

FIG. 2 is a flowchart showing the display operation of one embodiment. This operation is executed in accordance with an instruction from a CPU (not shown) based on a program stored in a ROM (not shown).

First, it is checked whether a display request has been received from the input unit 4 (step S1). If no display request comes, the process loops until a display request comes. When a display request is received, it is checked whether the display request is a request for displaying an average failure interval (step S2).

If the display request is an average failure interval display request,
Proceed to step S3. At this time, the screen in the initial state shown in FIG. In step S3, it is checked whether a search period has been input, and if not, the process loops. If it has been input, the process proceeds to step S4. At this time, the screen of the state shown in FIG.

In step S4, since the selected display request is the average failure interval, data of the average failure interval (target average failure interval) at the time of design is retrieved from the storage unit (database) 6 using this as a key. . FIG. 9 shows an example of this search result.
Shown in The average failure interval is displayed as data of the number. Next, the process proceeds to step S5, and the operation data (the number of productions, the number of failures, the repair time, and the like) for the period is searched from the database using the input search period as a key.

Next, proceeding to step S6, the number of failures for each station is counted from the retrieved operation data.
An average failure interval is determined from the number of failures and the number of productions for each station (step S7). The average failure interval is represented by a quotient obtained by dividing the number of productions by the number of failures. FIG. 10 shows an example of the average failure interval.

Next, the process proceeds to step S8, in which an attained value is obtained from the average failure interval for each station and the design value (target value). The achieved value is represented by a quotient obtained by dividing the actual mean time between failures by the design value. As shown in FIG. 9 and FIG.
In (ST number 1), since the design value is 850 (pieces) and the actual failure interval is 1360 (pieces), 1360/850 =
1.6. Hereinafter, the same calculation is performed to obtain the total achievement rate (%). FIG. 11 shows the calculation results.

Next, the process proceeds to step S9, where the sorting is performed in ascending order of the achievement rate, and the result is displayed on the screen (step S1).
0). FIG. 3 shows the display result. The above calculation and sorting are performed by the processing unit 3.

If it is determined in step S2 that the display request is not the mean failure interval display, the process proceeds to step S11. At this time, the display unit 5 displays the state shown in FIG. In step S11, it is checked whether a search period has been input, and if not, the process loops.
If the input has been made, the process proceeds to step S12. At this time,
The display unit 5 displays a screen in a state shown in FIG.

In step S12, since the selected display request is the average repair time, the average repair time at design time (target average repair time) is searched from the storage unit (database) 6 using this as the key. FIG. 12 shows an example of the search result. Next, the process proceeds to step S13, and the operation data (the number of productions, the number of failures, the repair time, etc.) of the input search period is searched from the database as a key.

Next, in step S14, the number of faults for each station is counted from the retrieved operation data, the sum of the repair time for each station is obtained, and the average repair time is calculated from the sum of the number of faults and the repair time. Find (Step S1
5). The average repair time is represented by a quotient obtained by dividing the sum of the repair times by the number of failures. FIG. 13 shows an example of the average repair time.

Next, the process proceeds to step S16, and a time ratio (%) is obtained from the average repair time and the design value for each station. The time ratio is represented by a quotient obtained by dividing the average repair time by a design value. At station 1 (ST number 1), the design value is 60 (seconds) and the average repair time is 89 (seconds).
89/60 = 1.483. Hereinafter, the same calculation is performed to obtain the time ratio. FIG. 14 shows the calculation results. Next, the process proceeds to step S17, where the images are sorted in descending order of the time ratio, and the result is displayed on the screen (step S10). FIG. 6 shows the display result. The above calculation and sorting are performed by the processing unit 3.

As described above, in the present embodiment, the storage unit 6 for storing the results of the simulation at the time of line design and the collected operation data, the search unit 2 for searching data from the storage unit 6, and the average of the searched data A processing unit 3 for calculating a failure interval and an average repair time, and a display unit 5 for displaying a result
And a selection unit (input unit 4) for selecting a display method of displaying the average failure interval or the average repair time. The result of simulation at the time of line design and the current operation status are displayed together, and the achievement rate By displaying the devices in order, it becomes easy to compare the design values (target values) with the actual data (operation data).

Further, the apparatus is arranged in ascending order of the achievement rate of the average failure interval simulated at the time of line design and the current average failure interval, or in descending order of the time ratio between the average repair time simulated at the time of line design and the current average repair time. By displaying, the order of devices to debug is
It can be understood at a glance, which contributes to the improvement of the operation rate at an early stage, and can shorten the start-up time and reduce the cost.

In the present embodiment, the achievement rate of the average failure interval and the ratio of the average repair time are individually displayed, but they may be displayed together.

Although the ratio is based on the data at the time of designing, the simulation may be performed again using the current average failure interval and the average repair time, and the ratio may be displayed based on the difference from the result.
