在分析Web 环境下生产调度系统体系结构的基础上,建立了基于XML(Extensible MarkupLanguage)的生产调度系统的通讯模型,设计了基于SOAP(Simple Object Access Protocol)协议的XML 引擎、XML 请求分发处理中的安全过滤器、请求分发处理器中的对象定义和交互过程,并探讨了将该模型用于实际生产调度系统中的实现技术。 关键词 生产调度系统可扩展标记语言 简单对象访问协议 通讯模型 Abstract: After analyzing the architecture of the production scheduling system under Web environment, an XML-based production scheduling system intercommunion model is proposed, and a SOAP-based XML engine, a security filter for XML request processing, the objects and the intercommunion process for request processor are designed. Based on the results, the implement techniques about how to use the model into the real production scheduling system is discussed. Key words: production scheduling XML intercommunion SOAP
