The actual data 100 includes a serial number 101 assigned to the ordered steel material, a test name 102 executed for each serial number 101, a test start actual time 103, and a test completion actual time 104. Times 103 and 104 are a start time and a completion time when the test corresponding to the corresponding test name 102 is actually carried out.

Next, the test plan for the steel material test by the test management system shown in FIGS. 1 and 2, the procedure for consistently managing the progress of the test according to this plan, the test results, etc. will be described with reference to FIG. It will be described according to the flowchart.

First, in step S1 (hereinafter simply abbreviated as S1), when the operator inputs a production plan according to the order from the keyboard 33 of the test management terminal 30, the LAN
The production plan data 70 of FIG. 4 is registered in the DB 15 by the DB access program 16 of the test management computer 10 via 50.

Next, in S2, the CPU of the test management computer 10
11 registers the test plan data 90 of FIG. 6 in DB15 according to a predetermined procedure. The data 90 is the test plan planning data 80 registered in advance in the DB 15 and the DB in S1 described above.
It is created based on the production plan data 70 registered in 15. Specifically, based on the planning data 80, the planning data 7
For each manufacturing number 71 of 0, the expected start time 93 and the expected completion time 94 of the implementation test corresponding to each of the implementation test names 73, 74, ... Are calculated back from the delivery date 72. As a result, the test name 92 to be performed for each manufacturing number 91
And the scheduled start time 93 and scheduled completion time 94 of the test of the corresponding test name 92 are obtained, and the test plan data 9 of FIG.
It is registered in DB15 as 0.

Further, in S2, the work load in each planned test is calculated, and the test plan data once set is reviewed using the calculated work load amount. Therefore, the graph of the workload amount according to the embodiment of the present invention in FIG. 8 is output.

This graph is output via the printer 14 or the output device 34 of the terminal 30. Also,
The data may be output from the printer 24 of the computer 20 or the output device 44 of the terminal 40 via the LAN 50.

The graph of FIG. 8 is created for each of the practice test names 73, 74, ... Of the production plan data 70.
In the graph, the vertical axis represents the test work load W and the horizontal axis represents the schedule D. The CPU 11 searches the production quantity (number of the production numbers 71) and the test quantity of each month for each test name by using the production delivery date 72 of the production plan data 70 as a key, and each of the tests scheduled in the plan data 90. The test time period (= test completion scheduled time-test start scheduled time) for each serial number is cumulatively added and graphed.

The operator on the management side, who sees the graph of FIG. 8 created for each test, may delay the delivery date if a period in which the work load amount W is concentrated (overloaded) is confirmed. Therefore, it is possible to review the plan data 90 so that the load W is not concentrated and the delivery date is not delayed.

On the other hand, the test implementation side looks at the graph of FIG. 8 created for each test, and if the load amount W is concentrated and overloaded, control is performed to improve this concentrated state. You can request on the side. The graph of FIG. 8 also serves as basic data for reviewing orders in addition to reviewing the test plan as described above.

Next, in S3, the CPU 11 of the computer 10 transmits the test plan data 90 created in S2 by the data transmission / reception program 17 to the test execution computer 20 via the LAN 50.

Next, in S4 and S5, the execution computer 20
The CPU 21 receives the test plan data 90 via the LAN 50 and the data transmission / reception program 27, and registers it in the DB 25 as the test schedule data via the DB access program 26.

Next, in S6, each test execution terminal 40
Search the DB25 test schedule data via AN50,
Based on the search result, the corresponding test device 60 is made to carry out the test to be carried out for each manufacturing number.

Next, in S7 to S10, each test execution terminal 4
0 obtains the test start actual time 103 and the test completion actual time 104 at the start and the completion of the test process performed by the corresponding test apparatus 60 by an internal timer (not shown). The obtained actual times 103 and 104 are transmitted to the execution computer 20 in association with the serial number 101 and the executed test name 102, so that the CPU 2 of the computer 20 accordingly.
1 is registered as test progress data in the database 25 via the data transmission / reception program 27 and the DB access program 26.

Further, the test progress data is sent to the test management computer 1 via the data transmission / reception program 27 and the LAN 50.
Since it is transmitted to 0, via the CPU 11, the data transmission / reception program 17 and the DB access program 16,
The test record data 100 of FIG. 7 is registered in the DB 15. The test progress data registered in DB25 is DB15.
It has the same contents as the test record data 100 of FIG.

Next, in S11, C of the test management computer 10 is entered.
The PU 11 uses the test planning data 8 registered in the DB 15 in advance based on the difference between the test planned process and the actual process.
Adjust the contents of 0. If the test could be carried out ideally according to the plan, the contents of the actual data 100 of FIG. 7 should exactly match the contents of the plan data 90 of FIG. Actually, there is a discrepancy between the two data due to the capability level of the operator who carries out the test, the work load situation, and the condition of the test facility. Therefore, the test planning data 8
The time 82 required for the 0 test needs to be adjusted according to the technical level of the operator who carries out the test, the workload condition of the operator, and the condition of the test facility.

Next, the adjustment of the test planning data 80 will be described. CPU 11 is DB15 test plan data 9
0 and the test result data 100 are collated, and the test scheduled time (= test completion scheduled time 94-test start scheduled time 93) and the test actual time (= test completion scheduled time 1) for each test name.
04-test start actual time 103) is calculated and compared.
If the comparison result, the scheduled test time> the actual test time, the time 82 required for the corresponding test in the test planning data 80 is subtracted, and the calculated actual test time is adjusted, and conversely, the planned test time < If it is the test actual time, the time 82 required for the corresponding test is increased and adjusted so as to be the calculated test actual time. In this way, the test planning data 80 can be regularly updated at the time required for the test actually obtained at the present time, so that the contents of the plan data 90 established based on the data 80 can be tested at the current time. The accuracy can be adjusted to suit the ability of the operator to perform the work, the work load, and the condition of the test facility.

Actually, the time required for each test varies depending on the condition of the work load at that time. Therefore, the time required for the test is calculated as follows: (degree of work load) × (normal time required) A method of obtaining the required time according to the work load amount W in FIG. 8 may be used.

The steps S1 to S11 described above are similarly repeated each time the production plan data 70 is input.

Although the production plan data 70 is input on a monthly basis, if it is input in smaller units, for example, every 10 days, the production plan data 70 will be reviewed by the review of orders and the test plan data 90 will be displayed. The review can be done in more real time.

The test plan data 90 and the test record data 100 registered on the test management computer 10 side have the same contents as the test schedule data and the test progress data registered in the test execution computer 20, respectively. . By providing redundant data between both computers in this way, it is possible to employ so-called fault tolerant in which even if one computer stops for some reason, the other computer can continue operation.

In this case, both computers constantly check whether the other computer is operating or not, and if it is stopped, the data and program are transferred to the other party and the processing is continued. Are maintained to appear non-stop.

FIG. 9 is a diagram showing the relationship between the quality control cycle of the test work and the effect in the test management system according to the embodiment of the present invention.

According to the series of procedures described above, in the test management system according to the embodiment of the present invention, as shown in FIG. 9, the test plan, the test progress and the test record in the test management work of the steel material can be consistently managed. Therefore, it is possible to reduce the load on the operator and improve the accuracy in planning and collecting the actual data. Further, it becomes possible to thoroughly manage the delivery date in the test work of the steel material, share the test information, and predict the load of the test work amount, so that the quality control cycle in the test work can be efficiently operated.
