What Is a Key Lot?

Batch management refers to the method commonly used in retrospective management in production and quality management when the manufacturing-type enterprise develops to the scientific management stage.

Batch management

Batch management refers to the entire production system from the input of raw materials to the delivery of the product.

Management comes from demand, and batch management is no exception. in

In chemistry, biology,

Application in Enterprise Management

If batch management is to be controlled within the enterprise, it must have a corresponding batch number for control. The establishment of the batch number is best to meet the management needs, and it is appropriate to express the direction of management and control.

Let me take the XX brake cup produced by a company as an example to explain the material flow process and batch management method:

1. The supplier of imported rubber and additives has its own production batch number. When a company checks the composition and viscosity during the incoming inspection, after confirming that it is qualified, the supplier's production batch number is used as the storage batch number.

2. Compounding rubber A company issued a compounding rubber production plan. The mixer blends imported rubber and additives in accordance with the formula. Each batch of the mixer is used as a batch number, which is defined by date + serial number. Inspection, testing of components, expansion rate and hardness, after confirming that they are qualified, put them in the compound rubber warehouse.

3. The shape and weight required for cutting the pre-formed compounded rubber into a brake cup, and the batch number of the compounded rubber is marked on the process flow sheet.

4. The vulcanized molding rubber is sealed on the vulcanizing machine with a mold. After vulcanization, the temperature, pressure and time specified in the process are separated according to different molds and cavities. The production date + mold + cavity is used as the batch number. Dimensional inspection.

Fifth, the package is shipped in accordance with the packaging method prescribed by Bosch, and the corresponding barcode is marked before shipment.

As can be seen from the above description, a product with a simple production process, because of strict quality requirements, contains three different batch numbers in the shipping information, and the content controlled by the three batch numbers is completely different. That is, it is not uncommon for a product to have multiple batch management.

As for the on-site management method, it can be placed in zones, different turnover boxes, and labeled with different colors or shapes. Where possible, gravity shelves can also be used. In short, for materials that need to be managed in batches, identification and relative isolation must be made. Simply put, batch management and visual management are closely related. The effect of batch management is directly proportional to the level of visual management.

Applications in the ERP system

Since there are management requirements, the ERP system must also support batch management. From the example of an automatic leather bowl produced by a company, if the batch management is supported, the system must meet the following requirements:

First, there must be a good correlation between the orders, to facilitate the traceability from the sales order to the production order to the purchase order, confirm the batch number of each link, otherwise it is empty talk. You will never find any batch of materials for the products you sell.

Second, the system must support batch management of materials, which is optional. This is required by most software.

Third, the embodiment of batch management in the system is achieved through the batch number. For materials with batch management requirements, the batch number field is not allowed to be blank.

Fourth, the system supports multiple definitions of batch numbers, and should support automatic generation of some fields, such as dates. I see a lot of software does not have this feature.

Fifth, for materials with batch management requirements, the compulsory delivery must correspond to the incoming batch, and the existence of negative delivery is not allowed.

It should be noted that batch management does increase the difficulty and cost of management. For the following specific operations, it is easy to cause confusion. However, as I said above: As can be seen from the above description, batch management is indispensable in the flow of materials. A professional batch management system has emerged to simplify the difficulty of batch management and easily improve the level of production management.
