Locating Disturbances in Semiconductor Manufacturing With Stepwise Regression

A.T. McCray, J. McNames, D. Abercrombie
2005 IEEE transactions on semiconductor manufacturing  
This approach can lead to excessive false alarms and limited sensitivity when the process contains more than one disturbance.  ...  This means process engineers will spend less time responding to false alarms and will be able to locate real disturbances more often.  ...  The processes in these simulations included 1 disturbance, a varying number of lots, and 25 steps. (a) Estimated probability of one or more FP errors.  ...

A novel flexible model for lot sizing and scheduling with non-triangular, period overlapping and carryover setups in different machine configurations.  ...  This poses another research challenge about how to model the sequence-dependency of minimum lot sizes in lot sizing and scheduling problems.  ...  to whether the quantity of cleaning product called minimum lot size is sequence dependent.  ...

Production lot sizing and scheduling with non-triangular sequence-dependent setup times

Alistair Clark, Masoumeh Mahdieh, Socorro Rangel
2014 International Journal of Production Research  
When setup times are triangular then stpr ≤ stpq + stqr and there is always an optimal lot sequence with at most one lot per product per period (AM1L).  ...  This paper formulates and explains a new optimal model that not only permits multiple setups and lots per product in a period (ML), but also prohibits subtours using a polynomial number of constraints  ...  Acknowledgements: Our thanks go to Socorro Rangel of UNESP for a critical reading of an earlier version of this paper, and to the anonymous referees who also made valuable suggestions for improving it.  ...

Procedural Urban Forestry [article]

Till Niese, Sören Pirk, Matthias Albrecht, Bedrich Benes, Oliver Deussen
2020 arXiv   pre-print
The effectiveness of our framework is shown through examples of large-scale city scenes and close-ups of individually grown tree models; we also validate it by a perceptual user study.  ...  The placement of vegetation plays a central role in the realism of virtual scenes. We introduce procedural placement models (PPMs) for vegetation in urban layouts.  ...  Given a lot and its zone type we then define a PPM that places vegetation individually into each lot.  ...

Lot sizing and scheduling: industrial extensions and research opportunities

Alistair Clark, Bernardo Almada-Lobo, Christian Almeder
2011 International Journal of Production Research  
Since then, researchers have developed successive generations of models combining capacitated and dynamic approaches, with a blurring of the boundaries between lot sizing and other research fields (Drexl  ...  Traditional models have been increasingly refined to incorporate more detail and integrate lot sizing with scheduling.  ...  They suggest a minimax core costs allocation which is then modelled as a mathematical programme and solved using commercial optimisation software.  ...

1992 The Journal of the Operational Research Society  
Some of the more interesting problems that arise in lot-sizing and lot-streaming are, at best, only satisfactorily solved for a single job.  ...  CONCLUDING REMARKS We have described a model which, in its most general form, requires decisions to be taken on batching and lot-sizing whilst a schedule is constructed.  ...

Factorial Models (Equation 3) As one moved from a fully nested model to a partially nested model for analysis of the data, the various F- ratios became more significant.  ...  Though the station factor was eliminated from the model LDTO, there was a very significant interaction between lots and opera- tors.  ...
