We introduce the batch sequencing problem (BSP) with item and batch availability for the singlemachine and two-machine ow-shop case. We propose a genetic algorithm which solves the BSP through a decomposition into a Phase I-Batching and a Phase II-Scheduling decision. The batch sequencing problem is closely related to the discrete lotsizing and scheduling problem (DLSP). Computational experienc...

This paper presents mathematical models and algorithms for a production scheduling problem with batch splitting of assembly operations. The operation precedence is represented in an operations network, and the operations at any particular workcenter are split into suitable batch sizes on the available identical parallel processors for faster completion. The solution methodology comprises of a b...

The Irix 6.5 scheduling system provides intrinsic support for batch processing, including support for guaranteed access to resources and policy-based static scheduling. Long range scheduling decisions are made by Miser, a user level daemon, which reserves the resources needed by a batch job to complete its tasks. Short-term decisions are made by the kernel in accordance with the reservations es...

In this paper, we firstly describe a technique named Duplicating, which duplicates machines in batch scheduling environment. Then we discuss several applications of Duplicating in solving batch scheduling problems, for the batch scheduling problem on unrelated parallel machines to minimize makespan, we give an (4− 2 B )-approximation algorithm and an (2− 1 B + ǫ) algorithm when m is fixed. We a...

The operation of a production facility has a major effect on the efficiency; therefore it is of upmost importance to find the best possible schedule. Due to the high practical expediency, the topic of batch process scheduling has gained growing interest in the last two decades and many approaches have been published to solve a wide variety of scheduling problems. In the present work first the d...

We propose a novel job scheduling approach for homogeneous cluster computing platforms. Its key feature is the use of virtual machine technology to share fractional node resources in a precise and controlled manner. Other VM-based scheduling approaches have focused primarily on technical issues or on extensions to existing batch scheduling systems, while we take a more aggressive approach and s...

This paper addresses a scheduling problem motivated by scheduling of diffusion operations in the wafer fabrication facility. In the target problem, jobs arrive at the batch machines at different time instants, and only jobs belonging to the same family can be processed together. Parallel batch machine scheduling typically consists of three types of decisions – batch forming, machine assignment,...

This paper is concerned with detailed scheduling of job-shop like manufacturing systems. It addresses the scheduling of jobs, either simple, requiring the manufacture of a batch of parts, i.e. simple products, or complex, comprehending the parts fabrication and their multistage assembly into a batch of products. The Product-oriented Scheduling approach was adopted, assuming that full scheduling...
