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. ...
A Class of Conflict Free Petri Nets Used for Controlling Manufacturing Systems
(1992)
This paper is devoted to the behavior, evaluation and management of non-cyclic discrete systems in general and manufacturing systems in particular. We introduce a special type of Petri nets called CFIOs (Conflict-Free nets ...
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 ...
Integrating Tradeoff Analysis and Plan-Based Evaluation of Designs for Microwave Modules
(1996)
Previously, we have described two systems, EDAPS and EXTRA, which support design and process planning for the manufacture of microwave modules, complex devices with both electrical and mechanical attributes. EDAPS integrates ...
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 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 ...
Selecting Flat End Mills for 2-1/2D Milling Operations
(2000)
The size of milling cutter significantly affects the machining time. Therefore, in order to perform milling operations efficiently, we need to select a set of milling cutters with optimal sizes. It is difficult for human ...
A User Interface for Discrete Optimization-Based Tradeoff Analysis
(1998)
The motivation of this thesis is to perform research in the arena of discrete tradeoff analysis. There are two fundamental aspects to the problem domain to be be studied. The first involves modeling the manner in which the ...
A Geometric Algorithm for Finding the Largest Milling Cutter
(2000)
In this paper, we describe a new geometric algorithm to determine the largest feasible cutter size for2-D milling operations to be performed using a single cutter. In particular:<p>1. We give a general definition of the ...
