Abstract:  An electric control board assembly process is studied for line balance improvement. To do so, according to the production process requirements, the operations in the process are standardized. Then, clustering analysis is carried out to the elements that should be assembled onto the electric control board. Based on the results of clustering analysis, the elements are grouped and their assembling order is determined. The assembling tasks for the element groups are optimally assigned to the workstations. In this way, the electric control board assembly line balance is improved. This method is applied to an enterprise as a case, results show that the line balance ratio is improved by 22.13% and productivity is increased by 35.99%. This is a significant improvement.

Key words: electric control board assembly, clustering analysis, line balance
