To batch or not to batch

Proceedings of the 2003 International Conference on Machine Learning and Cybernetics (IEEE Cat. No.03EX693), 2004
When designing steady-state computer simulation experiments, one may be faced with the choice of batching observations in one long run or replicating a number of smaller runs. Both methods are potentially useful in the course of undertaking simulation output analysis.

Batch-to-batch Optimization of Batch Crystallization Processes

Chinese Journal of Chemical Engineering, 2008
Abstract It is the fact that several process parameters are either unknown or uncertain. Therefore, an optimal control profile calculated with developed process models with respect to such process parameters may not give an optimal performance when implemented to real processes.

Batch-to-batch strategies for cooling crystallization

2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012
Two batch-to-batch (B2B) algorithms for supersaturation control in cooling crystallization are presented in this paper. In Iterative Learning Control (ILC) a nominal process model is adjusted with an additive correction term which depends on the error in the last batch.

An integrated batch-to-batch iterative learning control and within batch control strategy for batch processes

Proceedings of the 2005, American Control Conference, 2005., 2005
An integrated batch-to-batch iterative learning control (ILC) and within batch on-line shrinking horizon model predictive control (SHMPC) strategy for the tracking control of product qualities in batch processes is proposed. ILC is used for batch-to-batch control based on a batch-wise linear time-varying (LTV) perturbation model and the convergence of ...

Batching and Scheduling Jobs on Batch and Discrete Processors

Operations Research, 1992
We consider a situation in which the manufacturing system is equipped with batch and discrete processors. Each batch processor can process a batch (limited number) of jobs simultaneously. Once the process begins, no job can be released from the batch processor until the entire batch is processed.

Optimization of Batch and Semi-batch Reactors

2013
Abstract Batch and semi-batch reactors are widely used for fine chemical productions. The target in the fine chemical industry is to produce a high quality product and operational optimization is the key-element to match it. This work investigates how batch and semibatch reactors can be optimized in order to increase the yield of a desired product ...

Multivariate monitoring of batch processes using batch‐to‐batch information

AIChE Journal, 2004
AbstractMultiway principal component analysis (MPCA) and multiway partial‐least squares (MPLS) are well‐established methods for the analysis of historical data from batch processes, and for monitoring the progress of new batches. Direct measurements made on prior batches can also be incorporated into the analysis by monitoring with multiblock methods ...

Test for batch‐to‐batch variation in stability analysis

Statistics in Medicine, 1989
AbstractWe propose several statistical tests for batch‐to‐batch variation in the stability analysis of a drug product and present applications with data from new drug application stability and marketing stability analyses.
