一种基于设计任务的知识辅助系统研究

摘要

根据目前机械设计过程中知识应用存在的问题,以车辆动力舱设计为实例建立知识辅助系统,提出基于任务需求模型和知识辅助结构的知识辅助方法,即通过定义任务知识模型和用户知识模型,来定义和求解特定用户面对特定任务时的知识需求,并采用合理地组织知识辅助结构的方法,达到分层次地、主动地将所需要的任务知识提供给用户的目的.%According to the problems of knowledge use in design processes,proposes a knowledge supply method based on taskoriented knowledge requirement model and knowledge assistant structure is proposed-i.e.via the definition of task knowledge model and user knowledge model,define and solve the specific user's knowledge demand for some specific task;and via rationally and structural knowledge organization,realize the effect of providing required knowledge to user actively and layered,a ease study to power cabin of tank design is given.
