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 ...
Automated Generation of Group Technology Codes from a PDES Product Information Model
(1992)
The design and implementation of an automated system that generates group technology (GT) codes for microwave modules (MWM) is presented. An established GT coding scheme (MICLASS) was employed to capture the mechanical ...
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. ...
Integrated Manufacturing Facility Design
(1995)
This dissertation addresses for the first time the integrated problem of designing the manufacturing shop layout concurrently with its material handling system. Specifically, this study provides a method to derive shop ...
INformation Systems for Integrated Manufacturing (INSIM) - A Design Methodology
(1991)
Full control and management of information flow in manufacturing has not yet been achieved, mainly because of the data inconsistencies and lack of established functional relationships among different manufacturing application ...
An Optical Area-Scattering Based Approach for the Measurement of Surface Roughness Formed During Machining
(1993)
The measurement of surface roughness during a machining process is critical for the automatic control of surface quality in a computer-integrated manufacturing (CIM) system. In this work, a method of surface roughness ...
A Feature Based Approach to Automated Design of Multi-Piece Sacrificial Molds
(2000)
This report describes a feature-based approach to automated design of multi-piece sacrificial molds. We use multi-piece sacrificial molds to create complex 3D polymer/ceramic parts. Multi-piece molds refer to molds that ...
Generation and Evaluation of Alternative Operation
(1992)
This paper presents a new and systematic approach to assist decision-making in selecting machining operation sequences. The approach is to produce alternative interpretations of design as different collections of machinable ...
Run-to-Run Control Methods Based on the DHOBE Algorithm
(1999)
Many run-to-run (RtR) control methods have been developed in recentyears. Two particular set-valued RtR control schemes based on the Dasgupta-Huang OptimalBounded Ellipsoid (DHOBE) algorithm are introduced. Compared to ...
