Web-based Agricultural Machinery Parts CAPP System

With the application of manufacturing informatization and Web technology,it ispossible to exchange and share the resource of enterprises.The product design, production,manufacturing and sales of enterprise alliance have become a unified system.And CAPP isthe link and bridge in this system.The process design of traditional agricultural machineryparts is done by manual, which exists lots of defects. It is important to design a CAPPexpert system of farm machinery parts that is suitable for small and medium-sizedenterprises to use.Firstly,this paper introduced principle of expert system, the basic structure of expertsystem and Jess.Secondly, describing web technology that this system involved, such asthe J2EE, MVC, JSP, SSH2, etc.Thirdly,putting forward the overall design plan,thefunction modules and work flow of system.The paper introduced feature-basedmodeling,system process knowledge base, inference engine and process database.Finally,giving the operating results of system.
