An Algorithm And Its Emulational Experiment of On-line Scheduling Tasks on Uniform Machines Problem
【摘要】 对于局内同类机器加工任务排序问题设计了一种SpacePreparation算法 (简称SP算法 ) ,改进了经典LIST算法的平均执行效率 .文中证明SP算法的竞争比为 2 ,并通过仿真试验进行验证SP算法的执行效率
【Abstract】 For on\|line scheduling tasks on uniform machines problem, a new method named space preparation(Abbr. SP) algorithm is designed to improve classical LIST algorithm’s average performance efficiency. The competitive ratio of SP algorithm is proved to be 2 and its average performance efficiency is verified with its emulational experiment.
