Description

Smart management system for quality

The present invention relates to a smart quality management system, and more particularly, to a smart quality management system that allows quality control for each accessory of a particular product produced by each partner company to be automatically performed online.

In general, as consumer demands for electronic products increase and information and communication media such as the Internet and broadcasting develop, the importance of quality control of products sold and distributed is emerging.

Particularly, in the event of a defect in a product or part in a home appliance such as a TV, a DVD, a refrigerator, an electronic device such as a press machine or a milling machine, an electronic device such as a personal computer server, or a vehicle, a large quantity of recalled products are recalled. When quality control of a product or a part of a product fails, such as a lot of money loss is often caused to a manufacturer or a distributor.

Therefore, there is a need for a quality management system for continuous quality improvement by automatically collecting and statistically analyzing quality information in real time to measure and improve quality during the manufacturing process.

However, these systems often require high costs in manufacturing, installation, and maintenance, which makes them difficult for small and medium component manufacturers to utilize.

For example, the domestic auto parts industry has a multi-level structure that continuously subcontracts small and medium parts manufacturers, and small and medium parts manufacturers lack manpower and technical organizations for quality control and high cost of maintaining quality management system installation. Due to such reasons, the quality control of individual parts is not managed systematically.

This may also affect the quality of the automobile manufactured by the automobile manufacturer. The automobile manufacturer requires systematic quality control of the component manufacturer, and thus, the component manufacturer is burdened with cost for quality control of the component.

1 is a schematic diagram showing a smart quality management system according to an embodiment of the present invention.

As shown in FIG. 1, the smart quality management system of the present invention includes a terminal 100, a database 200, a quality management server 300, and an inventory management module 400 of a cooperative company.

First, the terminal 100 of the cooperative company is a network established in at least one cooperative company that manufactures each accessory related to a specific product, and receives the quality management information data for each accessory manufactured by the corresponding company. It serves to transmit to the server 300 for quality management.

In addition, the terminal 100 of the cooperative company may further include an inquiry program for checking the distribution rate, inventory, and shipping status of each cooperative company through the server 300 for quality management.

That is, the supplier can confirm the required result data according to the requirements of the accessories of each supplier through the inquiry program, and thus can manage the inventory and inbound and outgoing of accessories.

The database 200 stores reference numerical information on various accessories and information data of accessories for each supplier about the quality evaluation details inputted from each supplier.

In addition, the server 300 for quality control is in a state of being associated with the database 200 and is registered in the database 200 and quality management information data for each accessory inputted through a terminal 100 of a cooperative company. The reliability verification unit 310 compares various pieces of information data related to the accessory and performs the pass / fail decision of the accessory, and the contents of the pass / fail result determined by the reliability verifier 310 are determined by the supplier. And a notification unit 320 for notifying the terminal 100.

At this time, the server 300 for quality management operates a site for performing a web service to collect, provide, and process various kinds of information online, and to notify the result of this work.

In addition, the server 300 for quality control is built to further include a CTQ designation unit 330 for automatically performing selective designation for the CTQ (Critical To Quality) inspection accessory and the quality assessment no inspection accessory. It is built online to enable sharing of quality control information about the accessories and the server network of each affiliate that receives and uses the accessories.

Hereinafter, with reference to Figure 2 showing the operation process according to the smart quality management system of the present invention described above in detail.

First, when a supplier producing one accessory of each accessory constituting a specific product completes the production of the accessory, a quality inspection of the finished accessory is performed by itself.

At this time, the item for performing the quality inspection follows the pre-arranged matters with the product seller.

Then, the quality inspection report of the accessory whose quality inspection is completed through the above process is accessed through the terminal 100 of the cooperative company to the site operated by the server 300 for quality management, and then the server for quality management 300 Submissions are made by entering the relevant data in the data fields for each inspection item of the accessory presented.

In this case, the server 300 for quality control requests data input of each input target item related to an item of a corresponding accessory when a request for presentation of a quality inspection for an accessory to be delivered is provided by each supplier. Receive an inspection report for the accessory by displaying it on the screen and requesting input of the information.

The server 300 for quality control obtains reference spec data for the accessory of the item from the database 200, and compares the obtained data with the input data to check the quality of the accessory. Judge the pass or fail.

In addition, the server 300 for quality control transmits the information, which is determined to be unsuccessful, to the terminal 100 of the cooperative company, and inputs the accessory determined to pass. Allow reliability verification of the data to be performed.

At this time, the method for transmitting the information about the factory release to the terminal 100 of the cooperative company using a normal e-mail (e-mail), or the terminal 100 of the cooperative company to the server 300 for quality management In case of connection, the method of notifying by displaying on the screen is used.

On the other hand, the process of determining the pass / fail of the quality inspection based on the data input before the reliability verification as described above is a necessary process because the supplier performs only the quality inspection for the corresponding accessory and delivers only the accessories that have passed this quality inspection. Although it can not be seen, it can be considered a necessary process considering that even a defective product can be delivered as a normal accessory due to a mistake of the supplier.

On the other hand, when the quality inspection of the accessory is completed through the above-described process, the quality control server 300 controls the reliability verification unit 310 to verify the reliability of each input data for the accessory that passed the quality inspection Do this.

Here, referring to FIG. 3, whether there is a change in the scatter diagram formed by the data related to the existing accessory by the data of the corresponding accessory inputted to the server 300 for quality control through the terminal 100 of the cooperative company. We present a method of verifying reliability by verifying.

That is, when each data for a particular accessory is input, an existing inspection certificate for the accessory of the corresponding item is obtained from the database 200, and then the input data is calculated using the calculation logic of the F test for the input data. It is to verify the reliability of.

At this time, the standard deviation (σ) or the process capacity (Z) management level of the distribution of the data for each item of the accessory is preferably agreed with each supplier in advance.

In addition, the calculation logic of the F test is to test the reliability of the input data according to the difference of the dispersion of each data related to the corresponding accessory inputted previously and the variation of the scattering that changes when applying each data inputted from the current supplier. This method is mainly used for the techniques for normal statistical quality control.

Next, the inventory management module 400 self-evaluates the supplier in consideration of the distribution ratio calculation basis data according to the pass / fail through the server 300 for quality control, and the accessory arrival and departure and inventory status data of each supplier. To provide.

4, in the present invention, when the quality control server 300 performs the above-described reliability verification, when the number of rejection determination decisions on the accessory determined to fail is more than a preset limit, the production of the accessory is performed. By automatically designating a company (cooperator) as a management target company and registering it, it can be used as a material for managing a poor supplier.

That is, the inventory management module 400 compares the quality control information data of the accessory inputted from the cooperative company with reference numerical information about the accessory stored in the database 200, and the accessory meets the reference numerical value. In the case of receiving a pass evaluation, the supplier may be provided to the supplier in consideration of the preliminary distribution ratio calculation basis data, so that the supplier may provide data for making a decision on entry / exit and inventory of the accessory.

Therefore, in the case of the supplier, it is possible to reconsider the accuracy of the distribution factor considering the quality, delivery date, and price of the accessories, and increase mutual competitiveness according to the required quality, delivery date, and price compliance.

The present invention is not limited to the above-described embodiments, and the scope of application is not limited, and various modifications can be made without departing from the gist of the present invention as claimed in the claims.
