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 ...
An Application of Distributed Solid Modeling: Feature Recognition
(1994)
The availability of low-cost computational power is a driving force behind the growing sophistication of CAD software. Tools designed to reduce time-consuming build-test-redesign iterations are essential for increasing ...
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 ...
Representation of Spectral Profiles in the Auditory System, II: Detection of Spectral Peak Shape Changes
(1994)
Based on the ripple analysis model outlined in Part I of this paper, predictions are made for the detection of shape changes in spectral peak profiles. Peak shape is uniquely described in terms of two parameters: bandwidth ...
Detection of Binary Sources Over Discrete Channels with Additive Markov Noise
(1994)
We consider the problem of directly transmitting a binary source with an inherent redundancy over a binary channel with additive stationary ergodic Markov noise. Out objective is to design an optimum receiver which fully ...
Supervenient Hierarchies of Behaviors: Lessons Learned from a Vacuuming Robot
(1994)
In this paper we describe the use of behavior hierarchies based on ﲭerging two models of multi-layer architecture -- the supervenience model of [1] and the subsumption model of [4]. The behavior hierarchy approach allows ...
Generation of Feature-Based Models
(1994)
Often there can be a number of ways to perform machining operations on a stock to produce a part, and only some of them are cost- and quality-effective. To determine the best machining sequence, it is necessary that each ...
Robust Control of Set-Valued Discrete Time Dynamical Systems
(1994)
This paper presents results obtained for the robust control of discrete time dynamical systems. The problem is formulated and solved using dynamic programming. Both necessary and sufficient conditions in terms of (stationary ...
Visual Information Management for Network Configuration
(1994)
Current network management systems rely heavily on forms in their user interfaces. The interfaces reflect the intricacies of the network hardware components but provide little support for guiding users through tasks. There ...
Complexity of Production Management in a Petri Net Environment
(1994)
The objective of this paper is to show that Petri nets facilitate a comprehensive approach to production management and reduce the complexity of the problems involved at the expense of some constraints imposed on the ...
