Access Control for Manufacturing Process in Networked Manufacturing Environment

Access Control for Manufacturing Process in Networked Manufacturing Environment

The deficiencies of current access control techniques in solving the problems of manufacturing process access conflict in networked manufacturing environment were analyzed. An information model of manufacturing process was constructed, and a case XML Schema of manufacturing task model was given. Based on the characteristic analysis of the access control for the information model, an improved ac...

In-situ Process Control for Semiconductor Manufacturing

There is a critical need for exact, real-time reaction control of the chemical vapor deposition (CVD) systems that are used for semiconductor device manufacture [1]. At present, the development of real-time control for reactions within production-style reactor configurations is hampered by a number of issues: The nature, concentrations and physical distributions of the chemical species within t...

Process Monitoring and Control for Precision Manufacturing

New demands are being placed on monitoring systems in precision manufacturing because of recent developments and trends in machining technology and machine tool design. This paper first discusses the requirements for sensor technology for precision manufacturing process monitoring in general. Then, background and details are given about acoustic emission (AE) and the application of AE sensing t...

Integration of process planning and scheduling using mobile-agent based approach in a networked manufacturing environment

Effective and efficient implementation of intelligent and/or recently emerged networked manufacturing systems require an enterprise level integration. The networked manufacturing offers several advantages in the current competitive atmosphere by way to reduce, by shortening manufacturing cycle time and maintaining the production flexibility thereby achieving several feasible process plans. The ...
