| 摘 要： | 研究作业计划的随机性特征和工序时间波动对调度规则的影响。通过分析和研究不同作业间的工序时间分布关系 ,建立了基于时间参数的调度规则在两项任务间的工序时间随机分布存在重叠情况下的失效率的计算模型。在此基础上 ,采用概率分析法 ,进一步分析和建立了多项任务工序时间分布有重叠的调度规则失效率计算模型。采用该计算模型 ,分析了不同任务间的工序时间期望值相对差和工序时间波动幅度对调度规则失效率的影响

| Abstract: | In this paper, the issues are researched which include the features of randomicity of scheduling, the impacts on dispatching rule and its result by stochastic fluctuation of operation time in scheduling, the distributed relations of operation time between jobs. With probability analysis methods, the models to calculate failure probability of dispatching rule based on operation time are developed in case of some operation time overlap of two-job and multi-job. The effects are analyzed on failure probability of dispatching rule by the standard deviation of operation time and the difference of mean operation time among different jobs. |
