2. Description of the Related Art In order to manage the quality of a product, each of the departments related to the quality of the product, such as a technical department, a quality assurance department, and a manufacturing department, has, for example, a QC (Quality Control).
Quality control is performed based on the quality control method, and when a problem occurs, each department handles and improves the problem using an appropriate statistical method.

[0003] The problems that have occurred and their countermeasures are stored in a database or the like as trouble cases.
In each department, measures to prevent the occurrence of problems are examined and implemented, and efforts are being made for the customers to stabilize the quality of shipped products to customers.

[0004]

However, the efforts for quality control in the technical department, the quality assurance department, and the manufacturing department are individual responsibilities in each department. Within the scope of the department in charge, improvements and corrections have been made individually, but methods such as information transfer and data management have not been established for consistent quality control throughout the manufacturing process.

In some cases, the variation greatly affects the quality variation.

[0006] In addition, although the factors for quality control change every moment, changes in the factors causing various problems that occur in various departments are organized, and the related departments are notified in real time.
It was difficult to make various processes and judgments related to the change in the factor.

[0007] In such a situation, it is difficult to make diversified judgments as a whole manufacturing process, and it is not possible to make quick and accurate judgments to prevent the occurrence of problems. Therefore, there was no choice but to take post-improvement measures.

The present invention has been made in view of such a situation, and changes in factors for quality control are collected from a manufacturing department, organized and extracted for problems, and based on such information. , Technical department, and quality assurance department perform support processing to clarify the cause, determine whether or not the test method needs to be changed, and perform processing to predict the occurrence of problems. Is to be notified.

Personal computers 2-1 to 2-n
In addition, it is necessary to extract factors that have a dominant effect on the result (in this case, the quality of the product) as a management item input for each section or each production line. Is extracted based on scientific evidence.

In order to extract the cause of the problem, a characteristic factor diagram shown in FIG. 3 is used. The characteristic factor diagram is a diagram that systematically summarizes the relationship between the factors (causal systems) and the resulting characteristics, and is also called the "fish bone".
FIG. 9 is a diagram created for associating quality characteristics (results) and their causes (factors) with large bones and small bones and organizing them.

Using the characteristic factor diagram of FIG. 3, the extracted factors are listed, and the facts of each of the factors are verified to determine whether or not the factors are changed by external factors. As a result, the degree of influence on the quality management is determined for the factor that has become apparent, and the management items are determined by using the Pareto chart of FIG.

The Pareto chart is used to find important items in quality control. A bar graph is arranged for each item in descending order of ratio (or number of cases), and a line graph showing the accumulation of the ratio (or number of cases). Is a composite graph for determining a factor to be superimposed and managed based on information such as a cumulative index on the basis of scientific evidence. For example, when factors A to G are listed as factors affecting quality control, as shown in FIG. 4, using a Pareto chart, for a certain quality characteristic, out of the degree of influence on the overall result, By extracting the high-order items that occupy 80%, the three factors of factor A, factor C, and factor E can be determined as management items.

The management items determined in this way include “priority management items” using “person”, “production item”, “manufacturing quality” and “process” as change items, and “plan” as change factors.
It is divided into “daily change management items” using “production” and “evaluation”.

These management items are certified at three levels according to the number of days or the number of days.

The management items relating to “manufacturing quality” include, for example, a process defect rate (yield) and the number of defective shipment lots. These management items are certified at two levels according to their ratio or number. "process"
Management items related to, for example, manufacturing process audit results,
The degree of change in the manufacturing process, the presence or absence of a change in manufacturing equipment, the presence or absence of a part change, and the presence or absence of a part test run are included. These management items are certified at three levels according to their level.

FIG. 6 shows an example of daily change management items.
The management items related to “plan” include, for example, the timing of a change instruction, the presence / absence of a switching model, and similarity. In the manufacture of products, production plans are frequently revised depending on market sales and parts procurement. In order to prevent troubles caused by correction of the production plan, it is assumed that, for example, it is determined in-house (or in a factory) to check the production plan every three days. In such a case,
The “time of change instruction” in the management item includes not only the presence or absence of a change instruction, but also whether the change instruction was issued up to three days ago.
Or, it manages whether it was issued after that. These management items are binarized (that is, determined by で or ×) and determined by two levels.

The management items relating to “production” include, for example, the progress and progress of the production (the number of inputs to the production line and the number of completed products), the status of the work in progress, and the like. There are results. These management items are binarized and determined on two levels.
