This paper focuses on formulating a typical U-type assembly line balancing problem. A cost based objective function including equipment cost, worker time related cost, and station opening cost is introduced to be minimized in existence of a constant cycle time. Finally, efficiency of the proposed formulation of the introduced problem is studied and tested over some benchmarks.
