本文讨论了循环调度的一个单一的起重机在大型现实生活中的电镀生产线,其中一个部分访问一些处理槽不止一次,多个重复的坦克在一些生产阶段使用具有较长的处理时间。我们提出了一个正式的分析问题,并提出了一个有效的分支定界算法。发达国家的分析性能,使我们能够大大消除主导或不可行的解决方案,在分支定界过程。基准测试和实际算例的计算结果表明,该算法在大型电镀生产线调度问题上是非常有效的。
This paper addresses cyclic scheduling of a single hoist in large real-life electroplating lines, where a part visits some processing tanks more than once and multiple duplicate tanks are used at some production stages having long processing times. We present a formal analysis of the problem and propose an efficient branch-and-bound algorithm. The developed analytical properties allow us to considerably eliminate dominated or infeasible solutions in the branch-and-bound procedure. Computational results on benchmark and real-life instances show that the algorithm is very efficient in scheduling large electroplating lines.
