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 ...

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 ...

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 ...

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. ...

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 ...

A hierarchical approach to production planning for complex manufacturing systems is presented. A single facility comprising of a number of work-centers that produce multiple part types is considered. The planning horizon ...

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 ...

This study is an investigation into the mechanics in machining ceramic materials. Extensive experimentation is done in an effort to understand the process of material removal. The theory of fracture mechanics is used to ...

This paper presents a study on the mechanics of material removal for ceramic materials by observing single-point turning process of aluminum oxide (Al2O3). On-line cutting force measurement is performed and the surface ...

In this paper we consider the problem of constructing a network over which a number of commodities are to be transported. Fixed costs are associated to the construction of network arcs and variable costs are associated to ...
