Compared with the traditional mode of production, what changes in management thought and understanding have jit brought?

Many domestic enterprises often waste a lot when producing goods or products. Many customers are not short of products, but have accumulated more inventory. These unreasonable phenomena lead to a lot of waste. Toyota has adopted a new production management mode, namely JIT production mode. Its basic idea is:

The basic idea of JIT production mode is to "produce the required products in the required quantity only when needed", that is, to pursue a production system with no inventory or minimum inventory. The basic idea of JIT is the planning and control of production and the management of inventory.

JIT production mode takes just-in-time production as the starting point, first exposes waste such as overproduction, and then eliminates and adjusts equipment and personnel, thus achieving the purpose of reducing costs, simplifying plans and improving control. In the field control technology, the basic principle of JIT is to produce the right number of parts or products at the right time, that is, just-in-time production. It changes the previous procedure in the traditional production process into the latter procedure, and changes the latter procedure into taking goods from the former procedure according to Kanban. Kanban system is the core of JIT production site control technology, but JIT is not just kanban management.

One of the foundations of JIT is balanced production, that is, the average production of products, which makes the logistics flow in a balanced and balanced way among operations, production lines, processes and factories. In order to achieve balance, JIT adopts monthly plan and daily plan, and adjusts the plan in time according to the change of demand.

JIT advocates the adoption of specialized layout of objects to reduce queuing time, transportation time and preparation time, and adopts specialized layout based on objects at the factory level to make each batch of workpieces flow smoothly in each operation room and workshop and reduce the passing time. Adopting the specialized layout of micro-objects and the layout of work center at the assembly line and work center level can reduce the delivery time.

JIT(www.chinatpm.net) can make rational use of production resources, including labor flexibility and equipment flexibility. When the market demand fluctuates, the labor resources are required to be adjusted accordingly. If the demand does not increase much, it can be completed by properly adjusting the operation of operators with various skills; When demand decreases, we can reduce production shifts, fire temporary workers, and assign redundant operators to participate in equipment maintenance and repair. This is the meaning of labor elasticity; The flexibility of equipment refers to the consideration of processing problems in product design and the development of multifunctional equipment.

JIT emphasizes total quality management with the goal of eliminating unqualified products. Eliminate the root causes that may lead to nonconforming products and try to solve the problems. JIT also contains many factors that are conducive to improving quality, such as small batch, parts moving to the next process quickly, and quality problems can be found early.

JIT, driven by orders, closely links supply, production and sales through kanban, which greatly reduces material reserve, cost inventory and work in process and improves production efficiency.
