工程机械再制造过程信息追溯模型研究

Research on Information Tracing Model for the Process of Construction Machinery Remanufacturing

针对工程机械再制造过程信息追溯管理中存在的追溯过程复杂、物料关系信息与其对应加工过程信息不能建立有效的联系等问题,提出了基于活动的物料清单追溯方法,建立了工程机械再制过程活动网络追溯模型.该模型将整个再制造过程的追溯实体划分为产品(物料)、作业和活动,并采用巴克斯—诺尔范式对其进行规范化描述.构建了工程机械再制造过程信息模型,利用符号化追溯活动链和活动网络构建了追溯模型.基于活动的物料清单将物料关系与其对应的加工过程进行有效地融合,在此基础上的活动链和活动网络追溯模型简化了追溯流程.

Some problems hinder the achievement of information traceability management in the process of construction machinery remanufacturing,which are the complexity of tracing process and the difficulty of effectively integrating material relationship and information of manufacturing process.Based on the activity-based bill of material,a tracing method was proposed,and the tracing model for the process of construction machinery remanufacturing was built.In this model,the traceability entity of the remanufacturing process was divided into three classes：product,operation and activity,which were described with ＂Backus-Naur Form＂.An information model for the process of construction machinery remanufacturing was established,while a tracing model was built by using symbolic traceable activity chain and network.The material relationship and information of manufacturing were effectively integrated with the activity-based bill of material,and the tracing process was also simplified with the tracing model.
