A case study of batching in a mass service operation
Journal of Operations Management, 2002 Job batching is used extensively in manufacturing and the relevant theoretical considerations have been well-researched. However, while batching is also employed in mass services, it is not clear to what extent the manufacturing theory may be transferred.

Multivariate monitoring of batch processes using batch‐to‐batch information
AIChE Journal, 2004AbstractMultiway 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, 1989AbstractWe 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.

The look-ahead-maximize-batch batching policy
Seamless Interconnection for Universal Services. Global Telecommunications Conference. GLOBECOM'99. (Cat. No.99CH37042), 2002This paper introduces a new batching policy, called look-ahead-maximize-batch (LAMB), for reducing the bandwidth demand of video servers. LAMB maximizes the number of users admitted in a window, which includes the reneging time of all pending requests at that scheduling time.

In this work, we focus on the development of a parametric drift detection and isolation (PDDI) method for the handling of batch-to-batch parametric drifts in a batch crystallization process used to produce hen egg-white (HEW) lysozyme crystals. We consider that the batch crystallization process is controlled by an in-batch model predictive control (MPC)

Batch-to-batch model-based iterative optimisation control for a batch polymerisation reactor
Proceedings of the 2003 American Control Conference, 2003., 2004A batch-to-batch model-based iterative optimisation control strategy for a batch polymerisation reactor is proposed. Because the reference sequences for product quality variables during a batch are usually difficult to be set reasonably and the interest usually lies in the end-of-batch product quality, a modified quadratic objective function is ...

One of the basic principles in the investigation of suspected contact dermatitis is always to test with the patient's "own" product or chemical, the one to which he or she was actually exposed. An equally basic second principle is not to rely solely on a positive test reaction.

This work presents an integrated batch-to-batch control and within batch re-optimisation control strategy for batch processes using neural network models. To overcome the difficulties in developing detailed mechanistic models, neural network models are developed from process operation data.

Proceedings of the 23rd ACM SIGKDD International Conference on Knowledge Discovery and Data Mining, 2017
Efficiency of large-scale learning is a hot topic in both academic and industry. The stochastic gradient descent (SGD) algorithm, and its extension mini-batch SGD, allow the model to be updated without scanning the whole data set. However, the use of approximate gradient leads to the uncertainty issue, slowing down the decreasing of objective function.
