The assembly line is an effective combination of man and machine, which fully reflects the flexibility of the equipment. It organically combines the conveying system, the accompanying fixture, the online special machine, and the testing equipment to meet the assembly requirements of a variety of products. The transmission mode of the assembly line is synchronous transmission/(mandatory type) or asynchronous transmission/(flexible type). According to the choice of configuration, manual assembly or semi-automatic assembly can be realized. Assembly lines are indispensable in the mass production of enterprises.
The balance of the assembly line is to balance as much as possible between people or between machines, so that the output of the assembly line can reach the required level. Assembly line balancing issues are implicated in facility planning. The balance of the assembly line directly affects the productivity of the manufacturing system.
The problem of assembly line balancing is a problem that is implicated in facility planning. The total amount of work to be done by a workstation is the same as the total number of basic work units assigned to that workstation. The problem of assembly line balance is to assign all basic work units to each workstation, so that each workstation is busy in the beat (that is, the interval between two adjacent products passing through the end of the assembly line), and completes the most operations, so that each workstation is in a busy state. has the least amount of non-working time (idle time).
The balance of the assembly line is a very important issue in the design and management of the assembly line, because the balance of the assembly line directly affects the productivity of the manufacturing system. In the past few decades, people have carried out a lot of research on the balancing problem of the assembly line, and a lot of theoretical results have been obtained.
