This paper presents a case study of an implementation of a new method for Production Leveling designed for batch production. It includes prioritizing criteria of products and level production plan. Moreover, it was applied on a subsidiary of a multinational enterprise located on Brazil, which manufacturing processes comprise batch production in a make-to-stock policy. Regarding a qualitative as...

This paper describes the use of timed Condition/Event (C/E) systems, a real-time extension of the C/E system framework introduced by Sreenivas and Krogh, for building models of chemical plants in a modular fashion and as a basis for the model-based analysis of their discrete control. The approach is illustrated by applying it to the safety control logic of a laboratory batch process.

Would you like to have a 20,000 MHz machine capable of performing like a mainframe sitting on your desktop? Of course you would, but even with today’s rapid acceleration in microprocessor speeds 20,000 MHz is still a long way off. You may however, have 20,000 MHz of processing power sitting on “your” desktop if “your” is taken to mean your organization as a whole, and the organization has two h...

The paper addresses the problem scheduling a batch processing machine with multiple incompatible job families, non-identical job dimensions, non-identical job sizes and non-agreeable release dates to minimize makespan. The research problem is solved by proposing a mixed integer programming model that appropriately takes into account the parameters considered in the problem. The proposed is vali...

Parameter settings profoundly impact the performance of machine learning algorithms and laboratory experiments. The classical grid search or trial-error methods are exponentially expensive in large parameter spaces, and Bayesian optimization (BO) offers an elegant alternative for global optimization of black box functions. In situations where the black box function can be evaluated at multiple ...

This paper addresses a three-machine assembly-type flowshop scheduling problem, which frequently arises from manufacturing process management as well as from supply chain management. Machines one and two are arranged in parallel for producing component parts individually, and machine three is an assembly line arranged as the second-stage of a flowshop for processing the component parts in batch...

We consider a scheduling problem in which n independent and simultaneously available jobs are to be processed on m parallel machines. The jobs are delivered in batches and the delivery date of a batch is equal to the completion time of the last job in the batch. The delivery cost depends on the number of deliveries. The objective is to minimize the sum of the total #ow time and delivery cost. W...

There has been a proliferation of recent work on SMT tuning algorithms capable of handling larger feature sets than the traditional MERT approach. We analyze a number of these algorithms in terms of their sentencelevel loss functions, which motivates several new approaches, including a Structured SVM. We perform empirical comparisons of eight different tuning strategies, including MERT, in a va...

In this paper recent semi-batch chromium sludge processing is compared with batch processing by simulation means mainly. A possible time and/or power consumption reduction using these two techniques is monitored to optimize the process. The process itself is strongly exothermic so the temperature control is necessary to keep the temperature under critical temperature point.
