How to shorten the delivery cycle and flexibly respond to customer needs?

In the increasingly fierce global competition, what enterprises need most is the flexibility of internal and external supply chains. The higher the flexibility of enterprises, the faster the supply chain responds to the market, and the more opportunities for enterprises to accumulate competitive advantages. How to establish the flexibility of supply chain? Of course, we can use advanced information optimization technology to make changes as needed. But in essence, it should be to shorten the delivery cycle and respond to customer needs quickly. By shortening the production lead time, enterprises can quickly respond to changes in market demand. If our delivery cycle is shorter than the delivery time required by customers. It can realize the production according to the order and increase the flexibility of the supply chain, and it is not necessary for enterprises to hoard buffer inventory to meet the market demand. By shortening the production delivery cycle, the delivery time can be reduced and the inventory of finished products, semi-finished products and raw materials can be reduced; Reduce the spare parts inventory brought by customer's product replacement; Improve the ability to cope with delivery changes. For both internal and external supply chains, it is necessary to reduce cycle time, improve layout and network design, establish cooperative relationship between partners, simplify transaction processing flow, improve connectivity and implement pull replenishment system. Shortening the delivery cycle, responding flexibly to customers' needs, and making the flexibility of supply chain is not a myth or an unreachable goal. The following briefly introduces two ideas and technologies to shorten the delivery cycle, one is information technology and APS method; Second, industrial engineering and lean production methods. First, the composition of the delivery cycle From the time the customer places an order with the factory to the time of delivery, there must be a delivery date, which is the delivery cycle, also called lead time. It includes procurement lead time, production lead time and delivery lead time. Mainly to shorten the production cycle time, even if the production cycle time is equal to the product processing time, so that the production cycle time is shorter than the delivery time required by customers, so that the production can be flattened (balanced) and the production can quickly respond to the changes in quantity and variety, which also forms JIT production only when needed, only in the necessary quantity, and only produces the products needed "now"). Production cycle time = handling time+product processing time+inspection time+residence time 2. Information technology and APS method meet resource constraints and balance various production resources in the production process through APS advanced planning and scheduling; The optimal production scheduling scheme at different production bottleneck stages is given. Achieve rapid scheduling and respond quickly to changes in demand.

1, the production plan is automatically set to a dynamic lead time of seconds through limited capacity, and the fixed lead time of unlimited capacity is changed to a production plan of days. It can effectively shorten the production delivery time.

2. By decomposing the production order, the production lead time is shortened.

3. By dividing the work and allocating it to other resources, the manufacturing lead time can be shortened.

4. Through the method of working procedure connection, the batch number is reduced, so that the work of each working procedure is overlapped and allocated, thus shortening the manufacturing lead time.

5. By setting the connection point of pre-preparation and post-preparation time, the manufacturing lead time can be shortened.

6. Improve productivity and shorten manufacturing lead time through effective scheduling of operators.

7. By optimizing the scheduling of the bottleneck center, the previous process is pushed back and the latter process is pushed forward. Improve productivity to shorten production cycle.

8. Optimize the production process and shorten the manufacturing lead time through advanced mathematical constraint optimization algorithm. Iii. IE and lean production mode through the value flow analysis of the delivery process, non-value-added activities (generally accounting for more than 80%) are eliminated, that is, waste. The improvement direction of lean production is pointed out by using Little's law (lead time = inventory * production rhythm).

1, batch transfer through short handling distance and compression.

2. By changing the layout of unit flow production, the capacity balance and continuous production of each process are created.

3. Through kanban, the rhythmic flow of materials means that raw materials, work in process and finished products are reduced and production orders are consistent.

4. By changing internal preparation into external preparation and eliminating waste, the manufacturing cycle can be shortened.
