What Is Discrete Manufacturing?

The production process of a product is usually broken down into many processing tasks to complete. Each task requires only a small portion of the company's capabilities and resources. Enterprises generally build similar production equipment (departments, sections or groups) according to space and administrative management. In each department, workpieces are processed in different types from one work center to another. Enterprises often arrange the location of production equipment according to the main process flow to minimize the material transmission distance. In addition, its processing technology route and the use of equipment are also very flexible, and there are many changes in product design, processing requirements and order quantity.

The production process of a discrete manufacturing enterprise is often broken down into many processing tasks, and each processing task can be completed with very few resources. Various machining tasks required. In addition, due to the high degree of customization of discrete enterprise products, the parts processing technology and equipment are too flexible, making quality control extremely difficult. In terms of development, the difficulties in management and quality control of discrete manufacturing enterprises mainly include the following aspects:

Difficult to formulate mixed production

Most of the products produced by discrete enterprises are used in the manufacturing of special equipment such as mining, metallurgy, and construction. They are mainly large-scale equipment and have a high degree of customization. Taking a downstream heat exchange equipment manufacturing company in the petrochemical industry as an example, there are quite a lot of different types of heat exchangers according to various volumes and volumes. The materials and acceptance standards for each type of heat exchanger are different. The often existing "substitution of materials" also creates a good channel for standard mixing, resulting in an increase in loopholes in the quality management process.

Combining with the quality management of process-oriented enterprises, each product standard and material standard have strict procedures to control. Its construction in process management enables enterprises to respond adequately when facing special production conditions, but Due to the large number of materials and products in discrete enterprises, this special situation will frequently occur. This requires that on the one hand, the company has sufficient standardization and flexibility in the production management process, and on the other hand, it can provide enough convenient business Process processing method, that is, "on the one hand, standards should be managed, and on the other hand, standards should be managed."

Large production data and heavy data maintenance workload

For discrete enterprises, the diversity of products and the different standards of parts and components have led to an increase in inspection difficulty. Also taking the petrochemical industry as an example, a heat exchanger has no fewer than a thousand parts and components, and each part has fairly standard requirements. If you want to inspect the department one by one, and judge one by one, think about it. It's all a terrible thing.

How to process and manage production data? On the one hand, it is necessary to define the quality management responsibilities of each department from the work specifications. The production department provides data, the inspection department verifies and manages the data, and then the quality department reviews and judges the processed and classified data. As the company grows to a certain annual level, it will be more convenient to operate with the corresponding information system, and its responsibilities can be more clearly defined and traced.

High level of non-standard products and strong experience dependence

In discrete enterprises, there is often a name of "master and apprentice", because the production process, including the use of equipment, often depends more on the operator's technology and experience. Most companies take a lot of effort to hire a master to teach apprentices At the expense of hiring at high salaries, the extent to which discrete enterprises rely on experience is evident. Find a teacher to teach, "Let the experience stay", but the relationship between the teacher and the apprentice often appears "stay one hand", resulting in less and less production experience, and the quality of personnel is gradually decreasing.

If in the process of production management or even workshop management, the original "word-of-mouth" is changed to "paper-based", so that the process of teaching apprentices "explicitly, leaving traces", such as "apprentice diary" And so on, to retain the bit of daily experience and unfixable work content and methods, a little longer time can be formal documents or specifications to restrict and require, so as to achieve management standards and improve product quality.

Discrete manufacturing companies have far more factors involved in management and quality control than the above three aspects. The extended consultation summarizes as " explicit the invisible experience, regulate the irregularity, manage the uncontrollable, Manage well ", in the management process, you can also use a better management system and software to achieve better and more efficient management results. ^[1]
