If the production is arranged from the front process to the back process according to the traditional processing sequence, the higher the production efficiency of the process, if its rhythm is not suitable for the back process, the more waste of manufacturing surplus will be generated. Therefore, JIT production reverses the traditional way of transferring parts from front to back, and puts forward the order requirements from the back process to the front process according to the order method. The front process only provides the necessary products in the necessary quantity when necessary. Users can supply as much as they need, thus realizing "zero inventory" and not occupying working capital. Commodities that users do not need will not be produced, which can avoid overstock, obsolescence and deterioration of commodities, and can also avoid the costs of loading and unloading, handling and inventory.Application layer attackOEvent.cancelBubble=true;"Teacher, when I synthesize crystals, I need to find different conditions to synthesize them, but there are too many tests.
