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 ...
Sequencing Wafer Handler Moves to Improve the Performance of Sequential Cluster Tools
(2000)
Cluster tools are highly integrated machines that can perform a sequence of semiconductor manufacturing processes. The sequence of wafer handler moves affects the total time needed to process a set of wafers. Reducing this ...
An Algebraic Approach to Feature Interactions
(1990)
Planning the manufacture of machined parts requires a great deal of geometric reasoning. One of the key steps in this task is the derivation of machinable features from a solid model of the part. Regardless of the approach ...
Fixture-Based Design Similarity Measures for Variant Fixture Planning
(1999)
One of the important activities in process planning is the design of fixtures to position, locate and secure the workpiece during operations such as machining, assembly and inspection. The proposed approach for variant ...
Design, Verification and Implementation of Rule Based Information Systems for Integrated Manufacturing (INSIM)
(1992)
Full control and management of information flow in an automated factory has not yet been achieved, mainly because of the data inconsistencies and lack of established functional relationships among different manufacturing ...
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 ...
Fractal Geometry Applied to On-line Monitoring of Surface Finish
(1994)
Surface finish of machined parts determines the functionality of the product and also the machining requirements for making the parts. On-line monitoring of surface finish has been an active area of machining research. ...
Integrating DFM with CAD through Design Critiquing
(1994)
In research on concurrent engineering and engineering design, the increasing use of design for manufacturability(DFM) is expanding the scope of traditional design activities in order to identify and eliminate manufacturing ...
Integrated Approach for Hybrid Shop Layout
(1993)
This thesis presents a comprehensive methodology for the design of a hybrid manufacturing shop layout that comprises both manufacturing cells and individual workcenters. The proposed approach targets the minimization of ...
Integrated Dynamic Simulation of Rapid Thermal Chemical Vapor Deposition of Polysilicon
(1997)
A physically-based dynamic simulator has been constructed to investigate the time-dependent behavior of equipment process, sensor, and control system for rapid thermal chemical vapor deposition (RTCVD) of polysilicon from ...
