基于B/S结构的知识化制造自重构子系统的实现

为克服传统C/S结构的知识化制造自重构子系统维护成本高、执行效率低、通用性和可移植性差等缺点,开发了基于B/S的四层体系结构的知识化制造自重构子系统。介绍了知识化制造系统中知识的表示方法;分析了知识化制造自重构子系统的功能,讨论了知识网自重构使能工具的实现、自重构后实际软件系统的自动生成、基于混合编程的动态图形视图等难点技术;在ASP.NET平台上,基于组件技术,通过实例验证了知识化制造系统自重构的可行性及有效性。

Realization of Self-Reconfiguration Subsystem for Knowledgeable Manufacturing Based on B/S Framework

The self-reconfiguration subsystem for knowledgeable manufacturing based on the traditional C/S framework has such disadvantages as high maintenance cost,low execution efficiency,bad universality and bad transplant-ability.In order to avoid those disadvantages,the subsystem based on B/S framework with four-tier system structure is developed.Firstly,the knowledge representation in knowledgeable manufacturing systems is introduced in this paper.And then,the functions of the self-reconfiguration subsystem for knowledgeable manufacturing are given,meanwhile,the key technologies,such as the realization of enabling tools for self-reconfiguration of knowledge meshes,automatic construction of the real software system corresponding to its reconfigured knowledge mesh,and dynamic graphics view based on hybrid programming,are discussed in detail.Finally,on the framework of ASP.NET and by using component technique,the feasibility and validity of the self-reconfiguration for knowledgeable manufacturing are verified through the successful application to a practical system.
