计算机支持协作设计环境的开发研究

大型工程设计项目需要一支多专业设计队伍，并使用各种成熟有效、功能丰富的工程设计软件及工程数据库系统．为妥善协调各专业课题组的设计工作，并保证各工程软件及数据库、知识库的有效配合，有必要研究开发一种分布式智能设计环境．本文提出一种应用分布式人工智能（ＤｉｓｔｒｉｂｕｔｅｄＡｒｔｉｆｉｃｉａｌＩｎｔｅｌｉｇｅｎｃｅ）理论，采用异步智能服务单元（ＡｓｙｎｃｈｒｏｎｏｕｓＣｏｇｎｉｔｉｖｅＡｇｅｎｔｓ）技术集成所述各种工程软件的分布式结构．文章简要介绍智能服务单元的内部结构、分布式系统的总体结构、服务单元之间的通讯方式及相应的通讯协议等，然后介绍一种基于局部内的具有六个服务单元的试验环境，并提供一个简单的机械设计的实例

A Distributed Architecture for Computer Supported Cooperative Design

Large design projects require the cooperation of multidisciplinary design teams using sophisticated and powerful engineering tools. In order to ensure the coordination of the design activities of the different groups or the cooperation among the different engineering tools, it is necessary to develop an efficient distributed intelligent design environment. This paper proposes a distributed architecture for integrating such engineering tools in an open design environment organized as a population of asynchronous cognitive agents. In conjunction with the structure of a particular agent, the general architecture and the communication protocol, issues about the inter agent communication, blackboard architectures, and the task structure are discussed. A prototype of such an environment with six independent agents located in different workstations and microcomputers on a local network is presented. A small mechanical design example is used for testing such an environment
