Assembly line is well known as an important part in manufacturing process. It consists of several workstations that linked together to create a complete product. Each of workstation is doing their own tasks. However, during the process of item moving from workstation to another workstation to become a finished product, the unbalance of workload among workstation will create a bottleneck effect. This problem will cause the performance of assembly line is not optimal. Therefore, to improve the performance of assembly line, many methods are applied and used to solve assembly line balancing problem. In this paper, different methods which can be used to improve and balance the assembly line are discussed.
