Abstract

PROBLEM TO BE SOLVED: To provide a quality management system capable of quickly and accurately tracking a quality standard and a quality test record after the fact. SOLUTION: In the case that plural identification codes provided with the same quality management number as an inputted quality management number are present, the one related to the maximum value, that is the latest value, of a system management number (A part) is selected. There is a possibility that the same quality management numbers are present in a blank test record file. That is, the test record or test inspection report of the same product code (ABCD*L), the same plant (A), the same production line (H02), the same manufacture year, month and date (19960601) and the same manufacture time band (00) is present. Since the system management number is set so as to be surely unique, the entire identification code becomes unique. Since the system management number is automatically set and allocated by this system, an operator can not manually add an operation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The quality management system of the present invention is constructed on a computer system. In manufacturing a product, a product standard for the product is set, and the product standard is issued on a computer system. That is, the predetermined standard information is stored in a predetermined file of the computer. Then, a quality test method that conforms to this product standard is determined, and a test record or a base paper of the test record, that is, a blank test record, for recording the test results of the quality test performed according to the set test method. The base paper is set and stored in the file similarly.
In addition, a test inspection report or a base paper of the test inspection report, that is, a blank test inspection report base paper created based on the test results is created and stored in a file.

In parallel with this, quality control identification information for performing quality control of the product is created. The system management identification information includes information for specifying a product, information for specifying a factory that manufactures the product, information on the date and time of manufacture of the product, information on the name of the manufacturing process, and the like. In this case, the present invention includes an access counter as system management identification information managed by a computer for specifying access when a file related to the quality management is accessed. The access counter is automatically advanced each time an access to a blank test record base paper file or a blank test inspection report base paper file relating to product quality control occurs for writing. In the quality management system of the present invention, the system management identification information indicated by the access counter is managed and controlled together with the quality management identification information as identification information.

The latest value of the access counter is used to rewrite or create a product specification, test result, or the like in the blank test recording base paper file or blank test inspection report base paper file in which the last access occurred.
The identification information is given to the record or report data, etc., that is, the latest record of the quality control related file. The value of the access counter is automatically added on the computer system, and cannot be manually operated. Next, a test is performed for the quality test method set corresponding to the product, and the test result data is electronically input to the blank test record base paper created above. Further, test / inspection report data for a test / inspection report is created based on the data described in the blank test record base paper, and is input to the blank test / inspection report base paper.

The test record is a record of test result data,
A test report is created for evaluating product quality based on test result data. The contents of such input test records and test inspection reports are stored in files on the computer. These files are also included in the quality management related files. Then, even when the quality management identification information is the same, since the system management identification information is always different, the quality management related file is generated by managing both the quality management identification information and the system management identification information. Any record changes can be reliably identified. Then, any rewriting of the quality control identification information can be accurately tracked ex post facto together with the order.

[0013]

An embodiment of the present invention will be described below with reference to the drawings. In general, product quality testing includes process testing performed during the manufacturing or packaging process, product testing performed immediately after manufacturing, aging testing to see the aging during the quality assurance period after manufacturing, and market testing. There are market-product tests related to the quality of the provided products, and consumer-response tests performed in response to requests from consumers. Such various,
The management of test results is extremely complicated because multiple quality tests are performed on a product at irregular timings over a long period of time. Since it may be necessary to track records, precise management is required.

FIG. 1 shows a schematic system configuration of a quality management system according to an embodiment of the present invention. The quality management system 1 of the present example is configured on a computer network system including a plurality of computer terminals. For this purpose, the quality management system 1 of the present example includes a quality management server 2 that controls other terminals. The quality management server 2 includes a blank test record base paper file 3 for storing test record base paper, that is, a blank test record base paper for each product, for inputting a test result when performing a quality test of a product, and a description item of the test record. A blank test test report base paper file 4 for storing a test test report base paper, that is, a blank test test report base paper for each product, for inputting report data generated based on the test data, and associating the test result data with the product as it is. A test result data file 5 to be stored, a test record or test record file 6 created by inputting the test result data into a blank test record base paper, and a report data obtained based on the test result data are created. And a test inspection report file 7 to be executed.

The quality management system 1 of the present embodiment includes a computer terminal 8 having a file for storing a standard and a quality test method. The computer terminal 8 is connected to the quality management server 2 and updates the quality test standards and methods whenever the quality test standards and methods are changed, and records the blank test records as necessary. It is to be reflected on the base paper and blank test inspection report base paper. Further, the system 1 of this example is provided with a computer terminal 9 for inputting measurement values for inputting test results, and is connected to the server 2. Approval terminals 10 and 11 are provided for displaying test records and test inspection reports created by the person in charge and for approving the contents by each responsible person or each manager.

Next, a procedure of a quality control operation performed under the above-described quality control system will be described with reference to FIG. In manufacturing a specific product and providing it to the market, first, a product standard and a test method thereof are determined (step S1), and the contents are issued, that is, introduced into the quality management system of this example. Specifically, predetermined product standard contents for a specific product are stored in the standard file, test contents are determined and input via a computer terminal, and the contents are also stored in the file. Then, the blank test record base paper and the blank test inspection report base paper are respectively created based on the product standard and the test method (step S2), and stored in a predetermined file (step S3).

Next, a description will be given of the flow of operations at the product manufacturing stage. Preparations are made for testing on the manufactured product. In this case, the product to be tested is given identification information, in this example, an identification code composed of alphabets and numerals. This identification code is, as shown in FIG. 3, a system management number (part A) automatically added by the computer system of the present embodiment, and a conventional lot number including information necessary for specifying a product to be tested. It is composed of a known quality control number (part B). In this example, the blank section A is automatically added to the blank A by the computer system when the quality control number (section B) is created for a specific product.

The quality control number of this embodiment is composed of a product code, a factory, a workplace, a production line number, a date and time of production, and a code or number indicating the time of production. As a preparation stage for testing a product to be tested, the above-mentioned quality control number is input, and a product is sampled from a production lot for testing (step S4).
Sampling is also performed during the manufacturing stage of a product, but is also performed as appropriate with respect to aged products, marketed products, or products related to consumer reactions. In the case of a test for an aged product or the like, since the quality control number is also input at the manufacturing stage, a plurality of test records are created for the same quality control number. However, as will be described later, another system number is automatically assigned, so that the entire identification code is unique.

As another aspect of the test preparation stage,
Recall the stored blank test record base paper and blank test inspection report base paper for the product for input of the quality control number. Then, after confirming a predetermined test method for the product, an actual test is performed. The test result is input from the terminal (Step S5). In this case, it is possible to directly input the blank test record base paper, but in some cases, it is necessary to configure a separate input form, and then manually or automatically enter the blank test record base paper. Can be. And
A test inspection report is created based on the input items of the test record (step S6). Then, the content of the report table is determined (step S7). If the determination result is acceptable, the content is confirmed (step S8). If the content is not acceptable, the product and the test record are treated according to a predetermined procedure. (Step S9). This test inspection report is electronically stored in a predetermined file of the computer system (step S10).

Referring to FIG. 4, there is shown a procedure for assigning an identification code to a product to be tested or a procedure for retrieving a test inspection report or a test record based on a quality control number and updating, correcting, or the like. Have been. In this routine, an operator inputs a quality control number (part B) to specify a product to be manufactured or a product manufactured in the past (step S1). The system searches the system file for product standard data corresponding to the product specified by this input (step S2). Then, the system creates a blank test record base paper for inputting a test result corresponding to this product standard and a blank test inspection report base paper based on the blank test record base paper (steps S3 and S4). Then, all the identification codes are searched to detect and read the largest value, that is, the last record value, of the system management numbers used so far (steps S5 and S6). Then, the new system management number is determined by adding the system management number (step S7). As a result, the blank test record base paper and blank test inspection report base paper at the time of manufacture of the product are determined,
These are stored in predetermined files (step S
8 to S11).

Next, referring to FIG. 5, a test is performed on the specific product created and stored, and the test result is input to the corresponding blank test record base paper and blank test inspection report base paper, and the test record is entered. A procedure for creating a test inspection report will be described. The operator enters the quality control number of the product to be tested, accesses the blank test record base paper and blank test inspection report base file for the product, and creates the blank test record base paper file and blank test The test report base paper file is called, and a blank test record base paper and a blank test test report base paper for which a test record should be input or a test test report should be created are searched (steps S1 to S1).
3).

In this case, first, the system determines whether the quality control number is the input quality control number among the identification codes (step S4). If there are a plurality of identification codes having the same quality management number as the input quality management number, the one with the largest value of the system management number (part A), that is, the latest value is selected (steps S5 to S6). . For example, as shown in FIG. 6, in the blank test record base paper file, the same quality control number may exist. That is, there is a test record or a test inspection report of the same product code (ABCD * L), the same factory (A), the same production line (H02), the same manufacturing date (19996001), and the same manufacturing time zone (00). However, in this example, since the system management number is always set to be unique (222, 215), the entire identification code is unique (222-222).
ABCD * L-AH02199060100 and 2
15-ABCD * L-AH0219906060100)
It becomes something.

Since the system management number is automatically set and assigned by the system, the operator cannot artificially add an operation. The reason why test records or the like in which the above-mentioned quality control numbers are the same but only the system control numbers are different may occur when an input error is noticed and corrected after creation. But in this case,
Since both the data before correction and the data after correction are stored and stored, all the records relating to the same quality control number can be extracted by inputting the quality control number. Then, by comparing these, it is possible to know all the contents of correction at the correction location. For this purpose, the information stored in the system can be retrieved and displayed by a quality control number as shown in FIG.

As described above, in the system of the present embodiment, when the contents of the test record and the test / inspection report are changed, they are all stored in the system as separate records having different system numbers. A safe quality management system is constructed that cannot alter inspection reports. Next, the selected blank test record base paper and blank test inspection report base paper are output for inputting test results (steps S7 and S8). Then, the test result data is input to the blank test record base paper and the test inspection report base paper (step S9), and an automatic calculation is performed as needed (step S10), and a determination is made. If there is an error in the data input, re-input is performed (steps S8, S9 and S11). In this example, the test result data is stored in a file together with the standard values and the like as shown in FIG. Also, as shown in FIGS. 9 to 12, the information can be displayed or stored in a file in the form of statistical processing.

Further, these test result data can be used as a part of a test record or a test inspection report. Then, when the record and the inspection report have been created, they are electronically approved by the person in charge or the manager (step S12). After the approval procedure is completed, the test record and the test inspection report are assigned a new system management number (part A) as a formal record and are electronically stored (step S13). FIGS. 13 and 14 show examples of prepared test records and test inspection reports. In the system of the present invention, for example, as shown in FIG. 15, it is assumed that there are a plurality of managers and managers in approving test records and test inspection reports.
Approval can be obtained via network communication in order to receive the approval of these multiple managers and administrators.

In the above example, the identification code is created by a combination of alphabets and numbers.
The present invention is not limited to this, and arbitrary identification information can be used.

[0027]

As described above, the system management number (part A) automatically assigned and managed by the computer system and the quality control number (part B) indicating a product or a test record or a test / inspection report relating to the product. By assigning the entire identification code to the system, the management of complicated test records and test inspection reports can be managed very efficiently and accurately.
