基于知识重用的复杂产品可拓方案设计模型

大型复杂产品方案设计是一个多层次、多属性和创造性的配置过程,往往需要大量借鉴以往的设计方案。对方案设计过程中的多类型知识进行合理的建模与重用可以有效地支持方案设计的顺利实施。通过基元对设计过程中的各种类型知识进行基元建模,建立了基于基元模型的方案设计可拓集合,研究了基于知识重用的可拓方案设计问题,给出了知识可拓重用策略,提出了知识可拓重用推理模型,建立了基于知识重用的可拓方案设计模型。最后,通过实例验证了模型的有效性和可操作性。

Complex Mechanism Extension Scheme Design Model Based on Knowledge Reuse

Due to the complication,multi-hierarchy,multi-attribute and creative process of the complex mechanism scheme design,the design cases of the history scheme is alway reused in new scheme design.Reasonably organizing and reusing design knowledge is helpful to supporting the new scheme design.The design knowledge is described with the basic element,and then,the basic element extension set is put forward.The extension scheme design based on knowledge reuse is studied and the corresponding knowledge extension reuse strategies are given.Then,the reasoning model of knowledge extension reuse is presented and the extension scheme design model based on knowledge reuse is achieved.Finally,an example is provided to examine the models and the algorithms.
