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:
the production balance rate has been greatly improved;
the space utilization rate of the site is saved and the floor space is reduced;
optimize the 5s site for easy management and the overall look of the company;
the first mention is flexible, can be quickly switched, and quickly respond to the market;
