摘要:

为提高制造系统的快速结构配置规划响应速度,提出了基于图文法的可重构机床配置规划方法.使用图文法直观而形像地刻画动态体系结构的配置行为,利用基于图文法的平行模块配置技术,实现了体系结构图模型在具体系统配置规划中的物理实施,并使得图文法模型的图转换操作可以自动映射到实际配置系统的动态配置上.全面表达了可重构机床在配置规划中的相关特征和目标任务的对应变化,实现了平行模块配置规划技术.通过实例验证了该方法.

Abstract:

The paper presents a methodbased graph grammar of the configuration layout of reconfigurable machine tools in order to improve response speed of quick structure configuration layout of manufacture system.The configuration behavior of dynamic systematic structure is depicted by using graph grammar intuitively and formally.Configuration technology based on graph grammar of parallel module is adopted to achieve physics implementation of systematic structure graph model in idiographic system configuration layout.Graph conversion operation of graph grammar model is mapped automatically to dynamic configuration of actual configuration system.Correlative features of the configuration layout of reconfigurable machine tools are expressed roundly and corresponding correlative variety of aim assignment is described as well.Implementation of parallel module configuration layout technology is realized.Finally,a case study validates the proposed method.
