Optimal inspection policies for a partially observable process with hazardous inspections

Creator:

Chou, Chung-kuang

Abstract:

An inspection model is considered in which inspections are hazardous to the device being monitored. The model is formulated as a partially observable Markov decision process. Previous research has determined the optimal ongoing inspection policies for a previously inspected device. In this thesis, the optimal inspection initiation policies are investigated...

Dissertation
A hazardous-inspection model with costly repair

Creator:

Yang, Minghui

Abstract:

An inspection-repair model is developed that presumes inspection is hazardous to the system being inspected. The form of the optimal inspection-repair policy is determined for different ranges of the model's parameters. The model is formulated as a partially observable Markov decision process with finite numbers of states and actions. The...

Dissertation
Estimation of discriminant analysis error rate for high dimensional data

Creator:

Lebow, Patricia K.

Abstract:

Methodologies for data reduction, modeling, and classification of grouped response curves are explored. In particular, the thesis focuses on the analysis of a collection of highly correlated, highly dimensional response-curve data of spectral reflectance curves of wood surface features. In the analysis, questions about the application of cross-validation estimation of...

Dissertation
A linear programming and sampling approach to the cutting-order problem

Creator:

Hamilton, Evan D.

Abstract:

In the context of forest products, a cutting order is a list of dimension parts along with demanded quantities. The cutting-order problem is to minimize the total cost of filling the cutting order from a given lumber grade (or grades). Lumber of a given grade is supplied to the production...

Image pre-processing algorithms for isolation of defects in Douglas-fir veneer

Creator:

Forrer, Johannes Barry

Abstract:

The goal of this research is to develop automatic techniques for identifying defects in Douglas-fir veneer. To achieve this goal, computer vision techniques, in particular image-processing, will be applied. Several pre-processing steps may be required to enhance images in making further analysis easier, faster, and more reliable. Pre-processing is often...
