The advantages of assembly line balancing provide in knowledge is well known and many researchers actively discussing and doing their research in this field. There are many ways to solve the assembly line balancing problem, one of the techniques that frequently used in assembly line balancing is a simulation approach. In this paper, the power converter assembly line which has 27 major tasks and 19 workstations is studied. The line balancing problem is solved by using two heuristics methods and then, by using simulation, the results from both methods are compared and the best method is chosen.
