工件间具有串并有向图约束的单机随机排序问题
Single Machine Stochastic Scheduling with Series-parallel Digraph Constraints
【摘要】 研究机器发生随机故障的单机排序问题,其中工件间的优先约束为串并有向图,目标函数为极小化加权完工时间和,证明了此问题多项式时间可解,并给出了多项式时间算法.
【Abstract】 This paper deals with the single machine stochastic breakdowns scheduling problem,where the jobs are related by a series-parallel digraph,and the objective function is to minimize total weighted completion time,it is shown that the problem can be solved in polynomial time,and the polynomial algorithm is also presented.
