A New Class of Petri Nets for Modeling, Planning and Scheduling of Flexible, Manufacturing Systems
(1994)
This work addresses the modeling, verification, planning and scheduling problems of non-cycle discrete systems with emphasis on Flexible Manufacturing Systems. We introduce a special type of Petri nets, the Conflict-Free ...
Evaluating Sheet Metal Nesting Decisions
(1998)
This paper describes models that estimate the cost and time of sheet metal punching when nesting (batching) orders. These models help decision-makers plan production and evaluate the impact of changing the nesting policy. ...
An Architectural Framework for VLSI Time-Recursive Computation with Applications
(1993)
The time-recursive computation model has been proven as a particularly useful tool in audio, video, radar and sonar real- time data processing architectures. Unlike the FFT based architectures, the time-recursive ones ...
An Improved Algorithm for Solving Constrained Optimal Control Problems
(1994)
Motivated by the need to have an algorithm which (1) can solve generally constrained optimal control problems, (2) is globally convergent, (3) has a fast local convergence rate, a new algorithm, which solves fixed end-time ...
Minimum Mean Square Error Estimation of Connectivity in Biological Neural Networks
(1991)
A minimum mean square error (MMSE) estimation scheme is employed to identify the synaptic connectivity in neural networks. This new approach can substantially reduce the amount of data and the computational cost involved ...
Enumeration and Automatic Sketching of Epicyclic-Type Automatic Transmission Gear Trains
(1993)
The automotive transmission maintains a proper equilibrium between the power and torque produced by the engine and those demanded by the drive wheels. Most automatic transmissions employ some kind of epicyclic gear mechanisms ...
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 ...
Adaptive Array Systems Using QR-Based RLS and CRLS Techniques with Systolic Array Architectures
(1991)
In this dissertation the basic techniques for designing more sophisticated adaptive array systems are first developed. Then several systolic architectures based on numerically stable and computationally efficient algorithms ...
Reconfiguration for Programmable ASIC Arrays
(1992)
In an approach recently proposed for the yield enhancement of programmable gate arrays (PGAs), an initial placement of a circuit is first obtained using a standard technique such as simulated annealing on a defect-free ...
"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 ...
