What is the application effect of factory lean layout planning in manufacturing enterprises?

Application of lean layout planning in manufacturing enterprises

1, the definition of lean factory layout

Lean factory layout is based on the existing layout (or completely re-planning), using the method of value engineering analysis, by eliminating the waste of people, machines, materials, methods and environment, to achieve the best combination of the five, and to establish a systematic method to achieve effective management of the production system.

2. The purpose of lean factory layout

Lean factory layout is an inseparable part of manufacturing system, and its purpose is consistent with that of manufacturing system. Our traditional manufacturing system pursues "three reductions, three improvements and one improvement".

3. The relationship between lean factory layout and cost.

80% of the post-manufacturing cost is determined during product design, which can be confirmed in the cost-related improvement suggestions in the company's post-operation process. If the parts that must be replaced during the maintenance of mass production products can be confirmed by technology, the maintenance cost of products will be significantly reduced. Similarly, after we have determined the production layout of the workshop, the logistics cost in the whole production and operation process is also determined, and the logistics efficiency between the warehouse and the production line is also determined.

4. The relationship between general factory layout and waste.

There are all kinds of non-value-added activities in the workshop-waste. The part that the customer is willing to pay for the product is the most added-value part of the product. According to statistical research, value-added activities account for about 5% of the production and operation activities of enterprises. Necessary but non-value-added activities account for about 60%, and the remaining 35% is waste.

A bad site layout will bring a series of waste, such as waiting for waste (machines and others, people and others, people or machines and others, and so on). ), handling waste (too much forklift handling, various sizes of inventory and inventory management), low line balance rate, waste of operator actions (bending, walking, searching, etc.). Therefore, a reasonable and scientific site layout can minimize the hidden waste in the company's site, find and optimize the waste of receiving, moving, checking and exchanging tools, and eliminate the waste of waiting for the comprehensive utilization of materials and equipment.
