摘要
为了解决面向全球制造的大范围内企业间过程信息集成问题,必须由权威机构制定统一规范的中性转换语言。本文在分析PSLv2.0语言基础的知识交互格式的主要内容的基础上,阐述了基于本体论思想的PSLv2.0的语义基础和结构,总结了PSL与STEP的差别,以及PSL现存问题及其未来可能走向。
To solve the problem of how to integrate process information among co-located enterprises, a common specification should be established by an authorized organization. Based on the analysis and introduction of the main contents of Knowledge Interchange Format(KIF), the language foundation of Process Specification Language(PSL), ontology-based idea, and the implementation and semantic architecture of PSL v2.0 are narrated in detail. At last,the primary differences between PSL and STEP, the existing problems of PSL v2.0, and its future development are proposed.
