The critical jobs must be scheduled by the backward algorithm , which ensures the necessary resources allocated to the most important jobs ; then the remaining jobs are scheduled with a forward algorithm , which tends to allocate resources where the previous scheduling pass did not use them 算法中关键零件采用反向调度,尽可能地满足交货期要求;一般零件采用前向调度方法,利用剩余的车间资源,尽可能早完工。通过遗传算法的全局搜索,得到最佳的调度结果。
In this thesis , we first introduce give the definition of hidden markov models . then the methods to solve the three basic problems in the application of hidden markov models are introduced , namely three basic arithmetic : forward - backward algorithm , viterbi algorithm , baum - welch algorithm . also we present commonly model of hidden markov processes dynamic system 在这篇论文中,首先给出了隐马尔科夫模型的定义,接着介绍了隐马尔科夫模型实际应用中所面临的三大基本问题的解决方案,即隐马尔科夫模型三大基本算法:前向一后向算法、 viterbi算法、 baum ? welch算法。
