Abstract

Aiming at the improvement of the efficiency of the assembly line in the intelligent manufacturing field, a parallel U-shaped assembly line balancing problem (PUALBP) appears. In this paper, a mathematical model of the PUALBP-I is established, and an improved genetic algorithm (IGA) is innovatively designed based on the allocation strategy. Combined with 56 classic examples, the IGA is used to solve the mathematical models of SUAL and PUAL respectively, and the balance results and the balance effect evaluation indicators are obtained. The comparison with Parallel U-line Heuristic (PUH) shows that the results of PUAL are better than SUAL, and verifies that the IGA is effective. The results demonstrate that the IGA in calculating large-scale problems is superior to the small-scale problems, which provides a useful reference for solving PUALBP.

基于改进遗传算法的并行 U 型装配线建模与平衡

在智能制造领域，为了提高装配线的效率，出现了平行 U 型装配线平衡问题（PUALBP）。本文建立了 PUALBP-I 的数学模型，并基于分配策略创新性地设计了改进遗传算法（IGA）。结合 56 个经典实例，利用 IGA 分别求解 SUAL 和 PUAL 的数学模型，得到平衡结果和平衡效果评价指标。通过与平行 U 线启发式（PUH）的比较，发现 PUAL 的结果优于 SUAL，验证了 IGA 的有效性。结果表明，IGA 在计算大型问题时优于小型问题，为 PUALBP 的求解提供了有益的参考。
