面向协同虚拟制造的分布式支撑环境研究

提出了协同虚拟制造(collaborative virtual manufacturing, CVM)的概念及其主要内涵，比较了CVM与VM之间的联系与区别。作为VM的拓展和延伸，CVM可以被定义为基于网络技术、数据库技术和分布式计算技术，由制造商、供应商、合作伙伴和客户协同参与的支持供应链管理和个性化服务的虚拟制造。基于分层次、高度集成与松耦合的辩证统一和可扩展性的原则，给出了CVM体系结构，该体系结构同时考虑了供应链上企业之间的横向一体化和基于多层分布式对象技术的纵向一体化。分析了CVM与现有的分布式对象结构的主要矛盾，针对这一矛盾，提出了面向CVM的分布式支撑环境的主要技术内涵。给出了一个面向CVM分布式支撑环境的典型框架结构，该架构通过Web Service服务层整合异构分布式对象，并用传统的Socket通信方式以解决实时通信的问题。

Research on collaborative virtual manufacture oriented distributed supporting environment

The concept and main content of collaborative virtual manufacturing (CVM) are presented and relation and difference between CVM and VM are proposed. As the expansion and extension of VM, CVM could be defined as a kind of VM based on network, database and distributed computing technology, cooperatively participated by manufacturers, suppliers, partners and customers, and supporting supply chain management and personalized services. According to the principles of multi-layer, loose-coupling EAI, and extensibility, considering transverse integrity between enterprises on supply chain and lengthways integrity based on distributed object technology, the architecture of CVM is given. The main inconsistency between CVM and distributed object technology is analyzed, based on which, the main technical content of CVM oriented distributed supporting environment is proposed. A typical frame of CVM oriented distributed supporting environment is provided. In this frame, isomeric distributed object is integrated by Web Service, and the problem of real-time communication is solved by berkeley Socket technology.
