Research On Manufacturing Grid And Its QoS-Based Resource Management System

With the trend of globalization, standardization, digitization and virtualization of manufacturing industry, Networked Manufacturing (NM), Virtual Manufacturing (VM), Dynamic Alliance (DA) and Agile Manufacturing (AM) are proposed to resolve the problems synchronously occurred, which are typically described as resource sharing and cooperative working among distributed enterprises. These manufacturing paradigms have come into effects and have made indelible contributions to the informatization of manufacturing.Nevertheless, for the lack of open system framework and powerful developing tools, many problems are still left unresolved to these manufacturing platforms, such as dynamic distributed resource management, general-purpose protocols and regulations, and so on. These disadvantages limited the flexibility and openness of these platforms, and so to their popularization.Under these circumstances, the concept of Manufacturing Grid (MG) is put forward as a general, normative and uniform platform for manufacturing. With NM as the working basis, Open Grid Service Architecture (OGSA) as the system framework, and Globus Toolkit3.2 as the developing tools, MG can not only provide necessary environment for resource sharing and collaborative working, but also provide excellent flexibility and extensibility. Therefore, MG would ultimately be a global grid-based manufacturing platform.From the view of economics, systematology and psychics, this dissertation expounds the self-organization manufacturing system and its evolution conditions. Meanwhile, by introducing the co-opetition game theory, it discusses the opportunism tendencies of enterprises. As a tremendous innovation to academic and application, MG would play an important role in manufacturing on its road to globalization and standardization. As the certification of validity, the Self-Organization Manufacturing Grid (SOMG) theory has been accepted by Engineering Index (EI).Furthermore, as the bottleneck of introducing grid technology to manufacturing, resource management is highlighted and studied intensively in this dissertation. With the consideration on non-technical factors, this dissertation gives detailed descriptions to the Quality of Service (QoS)-based resource management system. And, the functions of dynamic distributed resource management, real-time task analysis and disposal arc designed and implemented in order to satisfy customers' requirements.On the basis of OGSI (Open Grid Service Infrastructure) specification, a QoS-bascd Local Resource Manager (LRM) is established to carry out the works of information...
