 Abstract—Virtual cellular manufacturing has attracted a lot of attention in recent years because traditional cellular manufacturing is inadequate under a highly dynamic manufacturing environment. In this paper, a new mathematical model is established for generating optimal production schedules for virtual cellular manufacturing systems operating under a multi-period manufacturing scenario. Th...

This paper addresses the formal specification and description of manufacturing systems. It is considered the use of SDL (Specification and Description Language), a standard FDT (Formal Description Technique), to model the behaviour, data and structure aspects of a manufacturing system. SDL was originally developed for telecommunication systems (protocol specification and data processing). The a...

Manufacturing process of gear is fairly complicated due to the presence of various simultaneous motions of the cutter and the job. In this paper, an attempt is made to generate meaningful design data for a spur gear and the corresponding rack form cutter necessary for the manufacturing process. Using these information, solid models for the cutter and blank are developed and finally gear-manufac...

Global competition and rapidly changing customer requirements afe forcing manufacturing enterprises to assume new production styles and configurations. Today, the agility has to concem not just operations and technology aspects but also organization: in this framework the concept of virtual organisation seems to be a new emerging paradigm to improve manufacturing firm competitiveness. Several r...

The apprentice model is making a resurgence through online craft communities or virtual guilds. These groups are growing through the mainstreaming of computercontrolled manufacturing and the democratic sales channels of the internet. Similar to open-source software communities, virtual guilds have a pioneering role in championing new technologies, often with only niche applications. The future ...
