Man-machine material method ring is a comprehensive management method, also known as PDCA cycle. It includes four steps: planning, execution, inspection and improvement. This method is a cyclical process, in which each cycle should bring improvement. People refer to people who make products. Machine, equipment used to manufacture products. Materials refer to raw materials used to manufacture products. Method refers to the method used to manufacture products. Ring refers to the environment in which products are manufactured.
People, machines, raw materials, methods, and environment are called the elements of the human-machine law circle. Among these five elements, people are in the central position and driving position, just like a driving car. The four wheels of a car are machine, material, law and environment, and the driver is the main element. If there is no driver, the car will just stay put and become a waste.
Relevant explanation
In production, the normal operation of equipment and the quality of tools are another factor that affects the production schedule and product quality. An enterprise is developing, in addition to the improvement of people's quality, the external image of the enterprise is improving, and the equipment inside the company is also updating. Why? Good equipment can improve production efficiency and product quality. For example, cutting materials, the past hand saw was changed to machine saw, and the efficiency was improved by dozens of times. It turns out to be slow and inefficient, and it has to test people's physical strength.
People are relaxed and efficiency is improved. Therefore, industrialized production and equipment is another powerful way to improve production efficiency. In the production of industrial products, the division of labor is meticulous, and there are usually several or even dozens of accessories or parts, which are operated by several departments at the same time. When a part is not completed, the whole product cannot be assembled, which leads to the assembly process being stopped due to materials.
