产品多学科协同设计中基于语义推理的动态协调方法

Dynamic Coordination Principle and Method of Multidisciplinary Collaborative Product Design Based on Semantics Reasoning

一致性维护和协调是协同设计中的关键问题,针对产品多学科协同设计的多视图性和动态性的特点,引入了一种动态协调原理和方法,其主要思想是当某学科设计者在协同设计过程中根据需求在其学科视图模型中动态增删组件后,通过基于组件功能语义的推理机制,其他学科自动响应,进行各自学科视图模型的更新操作,从而实现多学科视图模型间的动态协调。采用JSP+JavaBean+Drools+Ajax及相关技术开发了一个原型系统,并以减速器设计为例进行了分析与说明。

Consistency maintenance and coordination are key issues in collaborative design.Aiming at the characteristics of multiple views and dynamic nature for multidisciplinary collaborative product design,a dynamic coordination principle and method were introduced.The main idea was when one discipline dynamically added or deleted some components in the discipline view model itself according to its demands,other disciplines would respond through a mechanism based on semantic reasoning about the components＇ functions and automatically update their discipline view models,and then the dynamic coordination among the multiple discipline view models was achieved in the collaborative design process.Using JSP,JavaBean,Drools,Ajax and other related techniques,a prototype system was developed,and a reducer was illustrated to validate the proposed principle and the method.
