this paper addresses a production and outbound distribution scheduling problem in which a set of jobs have to be process on a single machine for delivery to customers or to other machines for further processing. we assume that there is a sufficient number of vehicles and the delivery costs is independent of batch size but it is dependent on each trip. in this paper, we present an artificial imm...

Flow chemistry and continuous processing can offer many ways to make synthesis a more sustainable practice. These technologies help bridge the large gap between academic and industrial settings by often providing a more reproducible, scalable, safe and efficient option for performing chemical reactions. In this review, we use selected examples to demonstrate how continuous methods of synthesis ...

Motivated by applications in porcelain-making companies, we consider a type of optimization problems for batch-processing operations. In production, single machine with fixed capacity is used to process jobs. Several jobs can be processed together if their total size no more than the capacity. Batch-position-based learning effects are considered because workers become skillful gradually after t...

We consider the problem of minimizing the makespan(Cmax) on m identical parallel batch processing machines. The batch processing machine can process up to B jobs simultaneously. The jobs that are processed together form a batch, and all jobs in a batch start and complete at the same time. For a batch of jobs, the processing time of the batch is equal to the largest processing time among the job...

Energy saving is becoming increasingly important in batch processing facilities. Multipurpose batch plants have become more popular than ever in the processing environment due to their inherent flexibility and adaptability to market conditions, even though the same flexibility may lead to complexities such as the need to schedule process tasks. These are important features to producing high val...

As time-sharing machines are replaced by powerful desktop computers and farms of workstations replace mainframes, more and more users turn to workstations when they need CPU cycles for their batch jobs. Unfortunately, they do not find workstations a very friendly environment for batch processing. Since these types of machines were originally designed as a single user environment, they lack most...
