Abstract :
Assembly lines are important approaches for mass production of industrial products. Nowadays, these lines are also used for producing customized products in low volume. Undesirable balancing increases the cycle time and idle time and subsequently decreases production rates and line efficiency while augmenting the cost of system. These factors ultimately reduce the productivity of manufacturing systems. For this reason, the researchers and practitioners of production and operation management take a deep concentration on assembly line balancing problem. In this paper, Boisen’s theoretic principles of line balancing are studied in the first section. In the second section, the current situation of a sample firm is analyzed and accordingly a suitable mathematical model is used for balancing with respect to the optimal standard and constraints of the firm. This model has been solved with a branch-and-bound procedure using LINGO Software and the global optimum solution has been found. In order to evaluate the effect of balancing, proper indices have been calculated for the current and proposed designs. Based on this comparison, some conclusions about the improvement of system’s performance have been pointed out.
