带不可更新资源和总加权完工时间的单机排序问题的3-近似表算法

A 3-approximation list scheduling algorithm for a single-machine scheduling problem with a non-renewable resource and total weighted completion time criterion

Susumu Hashimoto, Shinji Mizuno

摘要:

研究了一类带不可更新资源和总加权完工时间准则的单机排序问题。当机器开始处理作业时,消耗不可再生资源。我们考虑的情况下,每个作业的权重的目标函数是成比例的资源消耗量。在这种情况下,该问题是NP难的。我们提出了一个3-近似列表调度算法。此外,我们证明了该算法的逼近比为3是紧的。

英文摘要:

This paper studies a single-machine scheduling problem with a non-renewable resource (NR-SSP) and total weighted completion time criterion. The non-renewable resource is consumed when the machine starts processing a job. We consider the case where each job's weight in the objective function is proportional to its resource consumption amount. The problem is known to be NP-hard in this case. We propose a 3-approximation list scheduling algorithm for this problem. Besides, we show that the approximation ratio 3 is tight for the algorithm.
