Abstract:
U-shaped production lines are regarded as an efficient configuration in Just-In-Time manufacturing and attract the attention from academic and industry. Balancing the workload in these lines is an unsolved problem and significant research has been done within the past two decades. So far, only a few optimization models have been developed and researchers and practitioners use these models to solve different variants of the balancing problem in U-shaped production lines. We present a novel integer programming formulation for U-shaped line balancing problems (type-1), where the cycle time is given and the aim is to minimize number of utilized stations. This new formulation has been tested on all of the benchmarking problems in literature and a paired t-test is also applied to provide a comparative analysis with the existing models. The analysis of the results shows that this novel integer programming formulation leads to significant improvement over the other models.
