2. customer needs
what problems did the customer encounter:
1. the material distribution method is a typical one-time large-scale distribution, which results in a large amount of materials on the site. it is difficult to trace the material once it is abnormal;
2. the flexibility of the wire body is not high (high, medium and low);
3. low space utilization;
4. a large amount of waiting time between stations due to unreasonable material replenishment methods and process design;
5. repeated product take-up to increase employee fatigue;
6. on-site information transmission is through "吼";
7. no anti-detention, misplaced measures lead to quality insecurity;
8. the scene is chaotic (5s poor).
lean production line analysis:
1. designing the layout and quantity of lean production lines according to tt;
2. the line body meets the requirements of flexibility and expandability, and can be continuously upgraded to meet the production needs of different products and different processes;
3. the lean production line equipment is modularized, and the lean production line can be assembled freely to improve the efficiency and longevity of the equipment;
4. according to pqpq (order quantity, process path), classify the line body.
lean production line benefits:
1. the production balance rate is greatly improved (large materials are loaded by beats);
2. the space utilization rate of the site is saved and the floor space is reduced;
3. optimize the 5s site to facilitate management and the overall look of the company;
4. the first mention is flexible, can be quickly switched, and quickly respond to the market;
5. the number of personnel is reduced and the experiment is saved.
6. adopt visualization plus information management to achieve rapid feeding and reaction.
