The stations are arranged in a way to have a continuous and constant material flow. In this paper a multi-objective formulation for assembly line balancing is introduced. As a solution approach a two-step approach is proposed. In the first step the problem in a fuzzy environment is converted to a crisp problem and in the second step an efficient solution of the crisp problem is found by fuzzy programming approach. The efficiency of the proposed approach is shown by a numerical example. </span>
