On the Determination of the Period Length in a Period Batch Control System [chapter]

J. Riezebos
1997 Proceedings of the Thirty-Second International Matador Conference  
Period Batch Control (PBC ) is a production planning system that has strongly been propagated as a simple and effective instrument in obtaining the benefits of Group Technology, such as short throughput  ...  In this paper we address the problem of determining the period length P and the number of stages (and hence PBC periods) N, assuming the total manufacturing lead time T = N*P is held constant.  ...  CONCLUSIONS This paper has treated the important trade off between the length of a period P and the number of periods N in a period batch control system.  ...

On Periodic Reference Tracking Using Batch-Mode Reinforcement Learning with Application to Gene Regulatory Network Control [article]

Aivar Sootla, Natalja Strelkowa, Damien Ernst, Mauricio Barahona, Guy-Bart Stan
2013 arXiv   pre-print
In this paper, we consider the periodic reference tracking problem in the framework of batch-mode reinforcement learning, which studies methods for solving optimal control problems from the sole knowledge  ...  In particular, we extend an existing batch-mode reinforcement learning algorithm, known as Fitted Q Iteration, to the periodic reference tracking problem.  ...  Usually, in batch-mode reinforcement learning, very few assumptions are made on the structure of the control problem.  ...

Efficacy of vaccination of 3-week-old piglets with Circovac® against porcine circovirus diseases (PCVD)

Bernhard Heißenberger, Christiane Weissenbacher-Lang, Isabel Hennig-Pauka, Mathias Ritzmann, Andrea Ladinig
2013 Trials in Vaccinology  
In a PCVD affected farm, a total of 1105 piglets from three consecutive farrowing batches were included.  ...  In this controlled, blinded and randomised study, Circovac Ò , an inactivated PCV2 vaccine was used for active immunisation of 3-week-old piglets (0.5 ml, i.m., one-shot).  ...  Concerning the batch as co-factor for the weight, there was no significant difference between the vaccinated and the control group, except at 13 weeks of age (end of the nursery period).  ...
