Note. Optimal Balancing of U-Shaped Assembly Lines
提出一个整数规划模型，用于求解U型装配线的最优平衡问题，能比以往方法求解更大规模的问题。
This note presents an integer programming formulation for determining the optimal balance for the U-line line balancing problem. It is shown that this model can optimally solve larger problems than previously reported.
