摘要:研究了工件带到时间的两阶段柔性流水作业的排序问题,基于求解流水作业和平行机问题的算法思想,提出两个相应的近似算法H(R)和H(MR(?)),证明了这两个算法的最坏情况性能比分别为3-1/m和2/5-1/m,讨论了界的紧性,并利用数值模拟以分析算法与最优值的近似性能比.
Consider a two-stage flexible flow shop scheduling problem subject to release dates. Based on the idea of solving the flow-shop problem and parallel machine problem, we provide two approximation algorithms H(R) and H(MRJ'). The worst-case performance ratios for the two algorithms are proven to be 3 - 1 5 1/ m and 5/2-1/m respectively. We discuss the tightness of the bound and do numerical simulation to analyze the approximation performance ratio between the algorithm and the optimal solution.
