摘　　要：在对飞机设计选材工作进行分析的基础上,提出基于浏览器/服务器(B/S,Browser/Service)结构的飞机设计选材专家系统总体框架和系统各功能的实现方式,并开发了系统的原型.该系统将基于规则、案例和模型的选材方法结合在一起,通过一个通用的推理机实现推理.该推理机功能通过CLIPS(C Language Integrated Production System)专家系统开发工具实现.该系统主要有3个工作步骤:选材的定性推理,材料检索和材料综合性能排序.用户可以方便地使用浏览器对系统进行访问和操作.该系统飞机机翼大梁选材实例验证了该系统的有效性,可对飞机设计人员的选材工作起指导作用.Following a discussion on aircraft-design material-selection,a browser/service architecture framework of materials selection expert system,together with its implementation and prototype,was put forward.The system integrated rule-based reasoning,case-based reasoning and model-based method,and it could reason with a general inference engine.The inference engine＇s function was implemented by a popular expert system development tool—C language integrated production system（CLIPS）.When this system functioned,it worked in these three steps： reasoning for qualitative selection results,searching materials from material database and ranking the materials to obtain a selection result.User could access the system with browsers conveniently.Its effectiveness was demonstrated by a case of wing-spar materials-selection.
