摘要
In this paper, we consider the scheduling problem in which the jobs are first processed on a single machine and then delivered in batches by a single vehicle with limited capacity to the respective customers located at the vertices of a star-shaped network. The goal is to minimize the makespan. We present a 3/2-approximation algorithm for the identical job size case and a 2-approximation algorithm for the non-identical job sizes case.
