A DTMEs-Based Digital Twin System Construction Method For Smart Factory

Abstract

Many enterprises have built their own digital twin factory model for physical factory planning, simulation optimization and real-time monitoring. However, the digital twin system, which has a single field, a short time cycle and unsinkable service, cannot fully reflect the interaction and integration of the physical and information world required by intelligent manufacturing. Therefore, the research on the construction method of the smart factory digital twin system with cross-domain and multi-model has an important influence on the application of smart manufacturing. In view of the above problems, this paper proposes the concept and composition of digital twin manufacturing ecosystem (DTMEs) based on the requirements and characteristics of product lifecycle, and analyzes the construction requirements of DTMEs for factory digital twin system, product digital twin system and supply chain digital twin system from the perspective of lifecycle. Finally, the smart factory digital twin system architecture is applied to the digital and intelligent upgrading of the hydraulic cylinder factory. The experimental results show that the intelligent improvement of the hydraulic factory, the reduction of Work-in-process inventory and the advance of delivery time, and prove the feasibility and effectiveness of the smart factory digital twin system.

Summary of Data Label Research under Smart Finance

“…At present, many large enterprises and departments, based on the research on large data labels, study their own task needs, establish data platforms, and establish their own label system on the platform, so as to achieve big data-related business services. For example, Wang Xia and Xu Xiangdong [28] gave the Research on the construction method of health care big data labeling system . The data label system of public security system [44,46,48] ,And some comprehensive label system studies [42] .Based on the labeling system, the knowledge map can be further constructed [40] , using labels to evolve supernetworks [26,27] ;And apply the data label build and manage the data platform [12] .…”
