Evaluating Product Machinability for Concurrent Engineering
(1992)
Decisions made during the design of a machined part can significantly affect the product's cost, quality, and lead time. Thus, in order to address the goals of concurrent engineering, it is important to evaluate the ...
"Manufacturing-Operation Planning Versus AI Planning
(1995)
Although AI planning techniques can potentially be useful in several manufacturing domains, this potential remains largely unrealized. Many of the issues important to manufacturing engineers have not seemed interesting to ...
Improving the Efficiency of Limited-Memory Heuristic Search
(1995)
This paper describes a new admissible tree search algorithm called Iterative Threshold Search (ITS). ITS can be viewed as a much-simplified version of MA*[2], and a generalized version of MREC [15]. ITS's node selection ...
Manufacturing Feature Instances: Which Ones to Recognize?
(1994)
Manufacturing features and feature-based representations have become an integral part of research on manufacturing systems, largely due to their ability to model correspondences between design information and manufacturing ...
A Simple Approach to Performing Set Operations on Polyhedra
(1991)
In performing regularized set operations on two solids, the most difficult step is boundary classification, in which the boundaries of each solid are split into portions that are inside, outside, or on the surface of the ...
Complexity Results for HTN Planning
(1995)
Most practical work on AI planning systems during the last fifteen years has been based on hierarchical task network (HTN) decomposition, but until now, there has been very little analytical work on the properties of HTN ...
Building MRSEV Models for CAM Applications
(1993)
Integrating CAD and CAM applications, one major problems is how to interpret CAD information in a manner that makes sense for CAM. Our goal is to develop a general approach that can be used with a variety of CAD and CAM ...
A Critical Look at Critics in HTN Planning
(1995)
Detecting interactions and resolving conflicts in one of the key issues for generative planning systems. Hierarchical Task Network (HTN) planning systems use critics for this purpose. Critics have provided extra efficiency ...
State-Space Search, Problem Reduction, and Iterative Deepening: A Comparative Analysis
(1993)
In previous work, Korf showed that by introducing one problem- reduction step into a state- space search, one could reduce the number of node generations from 0 ((2b)2d ) to 0 (bd ), where b and d are the branching factor ...
Recognition of Volumetric Features from CAD Models: Problem Formalization and Algorithms
(1993)
Automated recognition of features from CAD models has been attempted for a wide range of application domains in mechanical engineering. However, the absence of a clear mathematical formalism for the problem has made it ...
