Design and research of production line improvement for small and medium-sized manufacturing industry

A production line improvement standard flow based on IE methods is put forward, aiming at the small and medium-sized manufacturing enterprises with low production efficiency and high cost, combining with the actual production situation to formulate appropriate optimization scheme, so as to adapt to local conditions and optimize accurately. Taking the refrigerator production line of Z company as an example and selecting the appropriate optimization method according to the optimization process to improve it, the balance rate of Z company's production line has been increased by 26%, the maximum production capacity of one day has been increased by 64%, and good results have been achieved.
