“…These stringent demands, therefore, provided new impetus to the already on-going research effort to integrate the two essential computing subsystems of a manufacturing system, i.e. Coordination and control systems to address the new challenges faced by the manufacturing enterprise (Kate and Sarah, 1992;Aizono et al, 1997;Amit et al, 1997;Huang, 2002). Various new manufacturing paradigms emerged to optimize a manufacturing organization within the context of integrating the coordination and control functions like the bionic manufacturing system (Okino, 1993;Udea, 1993), the fractal factory architectural concept (Warnecke, 1993;Sinh et al, 1998), the holonic manufacturing concept, and the Net man frame work for decentralized manufacturing (Montreuil et al, 2000;Frayret et al, 2001).…”

Purpose -The manufacturing paradigm is shifting from being a central system to a distributed system and is increasingly becoming dependent on wide area networks for the management of information services. The information subsystem employed in a manufacturing setting is susceptible to getting congested when used in a wide area network setting during peak hours. The issue of information and control subsystem integration and the characterization of network congestion have been researched in this paper using faded information field architecture. Design/methodology/approach -A wide area network was simulated with all its associated components like routers, switches, gateways, etc. by programming a simulation engine. The simulation engine mimicked a wide area network employed in a manufacturing enterprise. Findings -The architecture holds the promise to address the integration and congestion issues in a manufacturing system by employing autonomous decentralized and autonomous information fading techniques. Results show the effectiveness of the proposed technique in addressing the issue of network congestion in a distributed wide area network. Originality/value -The issue of information and control subsystems of a manufacturing system has been reported earlier. However, the network-centric problems like congestion during peak hours of operation have not been addressed in these emerging paradigms. The research reported in this paper focuses on the congestion issue and could be useful to wide area networked manufacturing system designers and managers.

W7th the rapidly changing demands of markets and customers, agile system is brought forward. Agile system requires a dynamically evolving environment. System continuous evolution means that its scale and complexiry keep rising. This paper aims to enhance agiliy of the dynamically evolutiona?y system. So we consider the blight that results from heterogeneous data under the large-scale, complex and dynamically evolving environments. In this paper: an integration model for heterogeneous agile system is designed: also the related technologies are discussed: at last, an evaluation on this model and its technologies is cam'ed out.

“…These models were developed to guarantee the meeting of the control systems' deadline, and they are suitable for hard real-time applications but are not effective for sequential control. A new system structure for flexible distributed object systems has been proposed [10]. This structure makes it easy to develop and modify distributed control systems and change the scheduled execution of application objects, but there is no method for decreasing the total processing time of production.…”
