摘　　要：知识生成是工业知识自动化的基础,流程工业知识通常由定向任务驱动生成,如优化调度、优化操作、故障诊断等,其解决方案生成除需要了解运行机理及生产数据外,同时更依赖领域专家经验,此类知识表示形式难统一,移植性差,不便于共享及重用。针对乙烯裂解炉炉群资源调度优化问题,采用P-图求解方法,构建解决方案的超结构模型,设计用于表示知识的P-图本体以及数据库映射为知识的规则,自动生成RDF (resourcedescription framework)表示的解决方案知识,建立知识库。最后利用乙烯生产厂的实际生产数据,验证了提出方法的可行性与实用性。Knowledge generation is the basis of industrial knowledge automation.Process industry knowledge is usually generated by directed tasks,such as optimization scheduling,optimization operation,fault diagnosis,etc.The solution generation requires not only understanding the operation mechanism and production data,but also relying on domain expert experience.Such forms of knowledge representation are difficult to unify,poorly ported,and inconvenient to share and reuse.Aiming at the problem of resource scheduling optimization of ethylene cracking furnace group,the P-graph method is used to construct the superstructure model of the solution,which is designed to represent the knowledge of P-graph ontology and database mapping into knowledge rules,and automatically generate RDF(resource description framework)represents the solution knowledge and builds a knowledge repository.Finally,the actual production data of the ethylene production plant was used to verify the feasibility and practicability of the proposed method.
