团队协同设计理性模型

Design Rationale Model for Team Collaboration

针对当前的设计理性建模理论与方法不能完全适应协同设计过程,不能全面描述协同设计中的设计理性的问题.在对IBIS(issue-based information system)模型进行拓展和改造的基础上,结合协同设计的认知特征提出了团队协同设计理性模型.该模型包括2类要素,分别以不同类型的节点和连接线表示,其中设计问题、设计方案、设计知识、设计产品、协同过程和协同情境6个要素以不同类型的节点表示;设计行为要素描述设计过程中设计者的具体操作,以不同类型的连接线表示.最后以自动打标机的协同设计过程为例,阐述了文中模型的建模过程,建立了自动打标机团队协同设计理性模型,证明了该模型的可行性和有效性.

Because existing theories and methodologies of design rational modeling can＇t fully describe the design rational in collaborative design. The existing design rational systems have great difficulties to be used in collaborative design. Taking the cognitive characteristics of collaborative design into consideration, this paper presents a design rationale model for team collaboration by improving the IBIS（issue-based information system） model. This design rationale model for team collaboration mainly includes seven kinds of essential factors： design problem, design scheme, design knowledge, design product, collaborative process, design scenario and design behavior. The first six kinds of factors are represented by different types of nodes, while design behavior, which describes the operation of the designer, is represented by the edges between different types of nodes. Finally, we take the design rational of the collaborative design of marking machine as an example to prove the feasibility and validity of this methodology.
