离散型物联制造过程复杂事件模型描述

Model Description for Complex Events of Io T-based Discrete Manufacturing Process

面向制造过程事件组织和关联方面的统一语义描述,分析了离散型制造过程事件类型及关系;并建立了生产过程复杂事件结构模型。结合复杂事件操作符和可扩展标记语言(XML)语法语义,建立了基于XML的面向制造过程的事件描述语言(XEDL)。通过基于XEDL的油制辣椒生产过程事件模型描述案例,与常用复杂事件模型描述对比,说明XEDL语言在事件模型描述方面的优越性。

In view of unified description for events organization and association in manufacturing process,structural model of complex event was established by analyzing the event type and relationship in discrete manufacturing process. In addition,a XML-based event description Language（ XEDL） was built for productive event combining with grammar and semantics as well as operators on complex event. Compared with common description of complex event model,a XEDL-based description case of event in chili oil production was presented to illustrate the capacity and superiority of the proposed event description language.
