案例驱动的协同设计知识管理模型及实现

Case-driven collaborative design knowledge management model and implementation

为了建立一个面向用户、设计师、工程师和决策者的产品设计知识协同信息管理平台,有效利用案例中的设计知识,提出一种案例驱动的协同设计知识管理模型,该模型通过分析新产品开发中用户、决策者、设计师和工程师之间的设计知识流通模式,建立了基于案例的知识协同与信息交互过程的映射模型,提出了基于Markov模型的设计知识提取方法,构建了案例驱动的协同设计知识管理框架,并以软件形式实现。案例驱动的协同设计知识管理模型将已有领域案例的设计知识引入新项目设计问题的设计求解中,新产品设计开发和过程管理所需的所有设计信息均可通过领域案例设计知识库进行实时地设计知识获取、重用和进化,直至完成整个设计项目。以某品牌起重机造型设计方案在案例驱动协同设计知识管理软件平台上的具体应用为例进行验证,证明了所提模型的可行性和合理性。

To establish a collaborative information platform of product design oriented to users,designers,engineers and decision makers,and to utilize the design knowledge in cases,a case-driven collaborative design knowledge management model was put forward.Based on the analysis of design knowledge flow patterns among users,decision makers,designers and engineers in the development of new products,the mapping model of case-based knowledge collaboration and information interaction process model was established,an extraction method of design knowledge based on Markov model proposed,and the case-driven collaborative design knowledge management framework which realized in software with specific project was built.Through case-driven collaborative design knowledge management model,the design knowledge of existing domain case was introduced into design solution of new project design problem.All the design information needed for new product development and design process management could be obtained,reused and innovated in real-time from the domain case design knowledge base until the completion of entire design project.The specific application of case-driven collaborative design knowledge management software platform was taken as an example to prove the feasibility and rationality of the model by crane modeling design project.
