本文是一个仿真研究的报告，研究了一种混合装配/作业车间作业调度的动态方法，并在焊接车间作业中进行了特殊应用。JIT到货和JIT交付都被考虑在内。对不同利用率的调度规则进行了平均流时、延误作业百分比、平均延误、平均延误和平均提早等性能指标的测试。结果表明，对于平均流动时间，SPT准则是最优的。我们在本文中提出的MSLACK规则对于平均延误是最好的，它是平均延误和平均提前的总和。然而，目前还不清楚哪条规则对拖期工作的百分比最好。我们还考察了发布时间的改变对性能测量的影响。
This paper is a report of a simulation study that investigates a dynamic approach to scheduling jobs in a hybrid assembly/job shop, with special application to welding shop operations. Both JIT arrival and JIT delivery are considered. Various dispatching rules with different utilization are tested for the following performance measures; mean flow time, percentage of tardy jobs, mean tardiness, sum of mean tardiness and mean earliness. The results indicate that the SPT rule is the best for the mean flow time. The MSLACK rule, that we suggest in this paper, is the best for mean tardiness, the sum of mean tardiness and mean earliness. However, it is not clear which rule is the best for the percentage of tardy jobs. We also investigate the effect of changing the release time on the performance measure.
