The balance of the assembly line is to make the balance between the staff or the machine as much as possible so that the output of the assembly line can meet the required level. The assembly line balance problem is implicated in the planning of the facility. The balance of the assembly line directly affects the productivity of the manufacturing system.

        The problem of wiring balance is a matter of implication with facility planning. The total amount of work done by a workstation is the same as the total number of work units allocated to the workstation. The problem of assembly line balancing is to assign all basic work units to individual workstations so that each workstation is in a busy state in the beat (ie, the adjacent two products are separated by the end of the assembly line) and the maximum amount of operation is done, Of the minimum working time (idle time) at least.

        The balance of the assembly line is a very important issue in the design and management of the assembly line, since the balance of the assembly line directly affects the productivity of the manufacturing system. In the past few decades, there has been a great deal of research on the balance of assembly lines, and a lot of theoretical results have been obtained.
