What are the advantages of lean production over traditional production models?

The biggest advantage of Lean Manufacturing over traditional assembly line production is its flexibility.

In an assembly line production model, the location of the hardware equipment is relatively fixed, and the design of the production process must be based on the existing Layout. For a small number of diverse products, it is often impossible to achieve the most optimal production process due to the limitations of the Layout. Lean production can be adjusted at any time according to the needs of different products Layout. assembly line is a product of large-scale production, the pursuit of a single product or similar products to maximize the efficiency of the Cycle Time is generally set faster, for a small number of diverse products, the factory had to make a dilemma: or to endure the frequent change of the line brought about by the loss of efficiency, and sometimes even appeared in the previous order. For small quantities of diverse products, factories have to make a dilemma: either tolerate the efficiency loss caused by frequent line changes, sometimes even when the first product of the previous order has not yet flowed to the last production station, and the next order has already begun to be produced; or produce products for a longer period of time at one time and tolerate a large amount of inventory. Lean production, on the other hand, usually uses less manpower and a longer cycle time to complete the work, which can greatly reduce the frequency of line changeover and reduce the time of line changeover.

On the other hand, for products that are stable and the frequency of line changes is low, the traditional assembly line has certain advantages - detailed division of labor, with IE's continuous improvement of the line balance, it can achieve a rapid increase in productivity in a short period of time, and under the control of the conveyor belt speed, it can ensure that the productivity of the long-term stability of the production. Stability. Therefore, products with frequent changes in market demand are more suitable for lean production, while for stable market demand and single product type enterprises, it is relatively more suitable for assembly line production.
