摘要
在总结制造过程数据内容和分析现有制造过程数据表达方法的基础上,提出一种基于多色集合理论的制造过程数据形式化表达方法,将制造过程数据所涉及的活动、对象、关系置于统一的以过程为核心的数学模型框架中。给出基于多色集的制造过程数据模型与过程描述语言(Process specification language,PSL)核心语义的映射关系,并对PSL核心语义进行扩展定义,以保证制造过程数据具有规范的过程语义。以一个齿轮轴工艺过程制造数据形式化语义定义为实例,说明基于多色集合理论和过程描述语言相结合的形式化语义建模方法在统一组织和关联描述制造过程数据以及维护语义一致性方面的可行性与有效性。
Based on the summary of the manufacturing process data content and the analysis of current expression approach for manufacturing process data,a formalized and unified mathematical architecture to integrate the activity,object and relationship with the process as its core based on polychromatic sets theory is proposed.A mapping of polychromatic sets-based manufacturing process data model to process specification language(PSL) core ontology is carried out.Meanwhile,the extension of PSL core semantic is also conducted to realize the semantic description of manufacturing process data.A gear shaft manufacturing process application instance with formalized and semantic definition is given to illustrate the capability and effectiveness of the proposed model for providing unified organization structure,representing associated relationship and maintaining consistent semantic of manufacturing process data.
