并行工程环境下基于黑板的多自治体协同设计

在分析并行工程特点的基础上，论述了协同设计的实质。为了满足紧密藕合协同设计的要求，提出引用黑板机制和自治体；分析了协同设计的类型，按照协同的程度给出了三种协同设计的方式，并介绍了一种计算机支持协同设计环境；最后以消失模设计为实例，给出了基于黑板的多自制体协同设计系统的结构，并简述了协同设计过程。

BLACKBOARD-BASED MULTI-AGENT COLLABORATIVE DESIGN UNDER CONCURRENT ENGINEERING ENVIRONMENT

The essence of the collaborative design is expounded based on the analysis of the features of concurrent engineering. Also the quotation of blackboard mechanism and agent is put forward to meet the demand of close-coupled collaboration. The types of collaborative design are analyzed where three modes of collaborative design are raised according to different extent of collaboration. An environment of computer-support collaborative design is introduced. At last, the structure of the blackboard-based multi-agent collaborative design system is presented taking the lost foam design as the example and the process of collaborative design is discussed as well.
