单机的公平排序问题

Equitable Scheduling on a Single Machine

摘要:

我们介绍了一个自然的,但似乎尚未研究的泛化问题的调度工作在一台机器上,以尽量减少延误的工作。我们的推广在于同时考虑问题的几个实例。特别是,我们有$n$客户端在$m$天的时间内,其中每个客户端有一个单一的作业,每天有自己的处理时间和截止日期。我们的目标是为每一个$m$日提供一个时间表,这样每个客户都能保证他们的工作在至少$k \le m$日内达到最后期限。这对应于一个公平的时间表,其中每个客户端在整个$m$天的时间段内保证最低水平的服务。我们提供了一个彻底的分析这个问题的三个主要变量的计算复杂性,确定有效的算法和最坏情况下的棘手的结果。

英文摘要:

We introduce a natural but seemingly yet unstudied generalization of the problem of scheduling jobs on a single machine so as to minimize the number of tardy jobs. Our generalization lies in simultaneously considering several instances of the problem at once. In particular, we have $n$ clients over a period of $m$ days, where each client has a single job with its own processing time and deadline per day. Our goal is to provide a schedule for each of the $m$ days, so that each client is guaranteed to have their job meet its deadline in at least $k \le m$ days. This corresponds to an equitable schedule where each client is guaranteed a minimal level of service throughout the period of $m$ days. We provide a thorough analysis of the computational complexity of three main variants of this problem, identifying both efficient algorithms and worst-case intractability results.
