摘要
In this paper we study parallel-machine scheduling with job rejection, where the total processing time of the rejected jobs is required to be no greater than a predefined bound. The objective is to minimize the makespan of the accepted jobs plus the total penalty cost of the rejected jobs. The scheduling problem is NP-hard in the strong sense. We present a 2-approximation algorithm with a time complexity of O (n logn) by making use of specific data structure. We also develop a polynomial time approximation scheme (PTAS). Due to the job rejection restriction, some techniques for knapsack problems are applied in the development of our PTAS. (C) 2017 Elsevier B.V. All rights reserved.
