摘要
探讨了分批排序问题,分析了极小化加权总完工时间问题1|B,rj∈{0,r}|!!jCj的复杂性,证明了此问题的NP-完备性,并对一类特定问题进行了研究,给出了解决问题的近似算法,证明了其可行性,进而对算法的性能进行了分析,结果表明算法有效地降低了计算复杂度。
The problem of batch scheduling is discussed especially the problem, of minimizing the total weighted completed time,namely problems 1|B,rj=∈{0,r}|∑ωjCjBesides its analyzed and the NP-completeness is proved.Then this paper focuses on a class of special case of the problem and proposes an approximated algorithm to solve the problem.The proof showes that it is feasible and its capability is improved.
