We consider the problem of scheduling n jobs with release dates on m identical parallel batch processing machines so as to minimize the maximum lateness. Each batch processing machine can process up to B (B < n) jobs simultaneously as a batch, and the processing time of a batch is the largest processing time among the jobs in the batch. Jobs processed in the same batch start and complete at the...

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...

The issues of waste generation in batch process plants differ in many aspects to continuous plants. Despite the smaller-scale of processing, complexities from unsteady state profiles, discontinuities, and run-to-run variations make waste minimization in batch plant more challenging. In this paper, we present a systematic methodology for waste minimization analysis of a batch process. The method...

Mathematical modeling and simulation of microbial Polyhydroxybutyrate (PHB) production process is beneficial for optimization, design, and control purposes. In this study a batch model developed by Mulchandani et al., [1] was used to simulate the process in MATLAB environment. It was revealed that the kinetic model parameters were estimated off the optimal or at a local optimal point. There...

The Chalmers grouped actinide extraction (CHALMEX) process is focused on the co-separation of actinides from all other elements in spent nuclear fuel solution, with ultimate purpose transmuting into shorter-lived and less radiotoxic elements. Based solvent equilibrium distribution data fission products, a preliminary flowsheet was developed tested batch mode. consists one step CHALMEX FS-13 (25...
