Single machine scheduling to minimise resource consumption cost with a bound on scheduling plus due date assignment penalties
研究单机调度问题,其中加工时间和交货期均可调整,加工时间随资源投入递减,目标是在加权拖期与交货期成本不超过给定上限时最小化资源消耗成本,并设计了近似算法。
We study a single-machine scheduling problem in a flexible framework, where both job processing times and due dates are decision variables to be determined by the scheduler. We consider the case where each of the job processing times is a convex decreasing function of the amount of non-renewable resource that is allocated to the corresponding processing operation. Moreover, we consider two of the more common due-date assignment methods. For each of the methods, our objective is to find a solution minimising the total resource consumption cost, given an upper bound on the value of the weighted number of tardy jobs plus due date assignment costs. Since the problem is known to be -hard, we focus on designing approximation algorithms.
