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 presents a data-driven approach to diagnostics of systems that operate in a repetitive manner. Considering that data batches collected from a repetitive operation will be similar unless in the presence of an abnormality, a condition change is inferred by comparing the monitored data against an available nominal batch. The method proposed considers the comparison of data in the distri...

background and objectives: in the era of global industrialization, enzymes are being used extensively in the various sectors including food processing. owing to the high price of enzymes, various initiatives have been undertaken by the r&d; sector for the development of new processes or improvement in the existing processes for production of cost effective enzymes. with the advancement in the f...

Heat integration to minimise energy usage in multipurpose batch plants has been in published literature for more than two decades. In most present methods, time is fixed a priori through a known schedule, which leads to suboptimal results. The method presented in this paper treats time as a variable, thereby leading to improved results. Both direct and indirect heat integration are considered t...

Time-of-Use (TOU) electricity pricing provides an opportunity for industrial users to cut electricity costs. Although many methods for Economic Load Dispatch (ELD) under TOU pricing in continuous industrial processing have been proposed, there are still difficulties in batch-type processing since power load units are not directly adjustable and nonlinearly depend on production planning and sche...

Today, online transaction processing applications can downsize from mainframes to microprocessors. Commodity database systems, operating systems, and hardware came of age in 1993., -they surpassed the online transaction processing performance of proprietary solutions. There are lingering doubts about downsizing batch transaction processing applications. The doubts center on the ability of micro...

In a batch processing network, multiple jobs can be formed into a batch to be processed in a single service operation. The network is multiclass in that several job classes may be processed at a server. Jobs in different classes cannot be mixed into a single batch. A batch policy specifies which class of jobs is to be served next. Throughput of a batch processing network depends on the batch po...

Industrial Batch Polymerization System Zoltan K. Nagy, Ruediger Franke, Bernd Mahn, and F. Allgoewer Nowadays chemical and related processing industries are faced with the need of increasingly precise control of product properties to meet specific demands. It is recognized that nonlinear model predictive control (NMPC) is an excellent candidate as a key enabling technology for the continued suc...

‎in this paper, we study a flow shop batch processing machines scheduling problem. the fuzzy due dates are considered to make the problem more close to the reality. the objective function is taken as the weighted sum of fuzzy earliness and fuzzy tardiness. in order to tackle the given problem, we propose a hybrid electromagnetism-like (em) algorithm, in which the em is hybridized with a diversi...
