The unbounded parallel-batch scheduling with rejection

In this paper, we consider the unbounded parallel-batch scheduling with rejection. A job is either rejected, in which case a certain penalty has to be paid, or accepted and processed in batches on a machine. The processing time of a batch is defined as the longest processing time of the jobs contained in it. Four problems are considered: (1) to minimize the sum of the total completion time of t...

Unbounded parallel batch scheduling with job delivery to minimize makespan

We consider unbounded parallel batch scheduling with job delivery to minimize makespan. When the jobs have identical size, we provide a polynomial-time algorithm. When the jobs have non-identical sizes, we provide a heuristic with a worst-case performance ratio 7/4. c © 2008 Published by Elsevier B.V.

Optimal Semi-Online Algorithm for Scheduling on Two Parallel Batch Processing Machines

This paper deals with semi-online scheduling on two parallel batch processing machines with jobs’ nondecreasing processing times. Our objective is to minimize the makespan. A batch processing machine can handle up to B jobs simultaneously. We study unbounded model which means that B is sufficiently large. The jobs that are processed together construct a batch, and all jobs in a batch start and ...

Timely Responsive Online Scheduling Algorithm for Parallel Batch Processing

Online job scheduling has demonstrated to be a key factor impacting the output performance of batch processing systems. Existing researches either proposed solutions to a single-machine processing system, or focused on minimizing the total job completion time for multiple-machine batch processing systems. Yet the study on the approaches with the objective of minimizing the job delay time on a p...

On scheduling an unbounded batch machine

A batch machine is a machine that can process up to c jobs simultaneously as a batch, and the processing time of the batch is equal to the longest processing time of the jobs assigned to it. In this paper, we deal with the complexity of scheduling an unbounded batch machine, i.e., c = +∞. We prove that minimizing total tardiness is binary NP-hard, which has been an open problem in the literatur...
