【Overview of the production management bar code scheme】

Facing increasingly fierce market competition, many manufacturing enterprises have implemented ERP/MRP and other systems to help enterprises improve their management level and enhance their ability to cope with competition and changes. However, the upper-level production plan management is increasingly affected by the market, and the enterprise obviously feels that the plan cannot keep up with the changes. In the face of customers' strict requirements on delivery time, in the face of more product modifications, and the continuous adjustment of orders, enterprise decision makers realize that the formulation of plans depends on the market and the actual operation execution status, and cannot be completely based on materials. and inventory returns to control production. At the same time, ERP/MRP software is mainly aimed at resource planning. These systems can usually deal with what happened before yesterday (for historical analysis), and can also predict and deal with the events that will happen tomorrow, but they often leave behind the events that are happening today. Irregular gaps. Therefore, the on-site management of production has always been in a state of black-box operation, which can no longer meet today's complex and changeable competition needs. Therefore, how to make this black box operation transparent, find out any problems that affect product quality and cost, improve the real-time and flexibility of the plan [production site management system], and at the same time improve the operation efficiency of the production line has become the concern of every enterprise The problem.

Why should the production management introduce barcode]

1) The production site will generate a lot of real-time [production site management system] useful data, and these production data will play an important role in the rapid decision-making of the enterprise.

2) The data on the production site is mainly collected by the operators on the production site. Since the operators on the production site are both responsible for production and data collection, if the original manual collection method is used, the input speed is not only slow, but also the error rate is high.

3) The data on the production site is scattered in many different process links. It is necessary to use the barcode as a link to connect the information of each production link, so as to track the whole process of the product from the production start to the finished product.

【How to introduce barcode into production management】

1) Use process cards printed with barcode symbols.

According to the production order or production plan, the process card is printed out with a barcode printer before each single product or each batch/order product starts to be produced; the process card corresponds to a single product or a certain batch of products one by one, and During the production process, as the product circulates in each link of the production line, in each production link, the production site operator scans the barcode on the process card with a barcode reader or a handheld terminal to obtain the production data of the previous production link. And record the relevant information of this operation link on the process card until the product is formed and packaged.

2) The items to be collected are indicated by barcode symbols and printed on the label.

For example, each management object can be identified with a unique identity serial number, and the serial number barcode label can be printed and pasted on the management object that needs to be tracked. At the same time, some auxiliary data objects (such as process, operator, production line, production shift, etc.) can also be barcoded to further realize the automatic collection of data.

3) Use a handheld data terminal with barcode scanning function for production management.

For applications where computers cannot be arranged on the production line, data collection is not required in real time, and the data in each link has no correlation or strong correlation, hand-held data terminals can be used to collect first in a decentralized manner, and then process them in batches. At this time, the production site operators are equipped with hand-held data terminals with barcode scanning function for on-site data collection. At the same time, relevant information can also be inquired on the spot, and the relevant data in the system will be downloaded to the handheld terminal before that.

4) Data upload and synchronization.

Upload the data collected on site to the production management system, and automatically update the data in the system. At the same time, the updated data in the system can also be downloaded to the handheld terminal for on-site query and call.

[Features of the production management bar code system scheme]

Pay attention to the management and control of the production site operation process, which is characterized by the application of bar code technology.

The advanced bar code technology is used to comprehensively identify the data that needs to be collected in the production site operation, and realize the automatic and rapid collection of a large amount of real-time data generated during the production operation.

In the process of production management, a barcode identification is given to each data management object in the enterprise:

1) After the barcode reading device swipes the barcode identification, the barcode will be interpreted to accurately identify each data management object.

2) The detailed information of the identified data management object is stored and transferred to the computer, and the collection of the data is accurately completed.

3) The automatic error correction and real-time alarm function fundamentally eliminates the unavoidable error phenomenon in the past manual input, and ensures the complete authenticity and reliability of the first-hand data in the grass-roots data statistics.

Perfect integration with planning layer to enhance the application value of ERP/MRP system

On the basis of solving the bottleneck problem of data collection and input in the original ERP/MRP system, it maintains two-way communication capability with the planning layer (ERP/MRP), receives corresponding data from the planning layer and feeds back processing results and production instructions, thereby improving ERP/MRP.
