Simulation-based Digital Twin

• PROJECT DESCRIPTION:

  • A project with one of the smart warehouses in Taiwan. 

  • The need for improving flexibility, optimality, and transparency of industry processes increases since the customer demands are highly diverse and full of uncertainty. Cyber-Physical System (CPS) technology now is being developed to meet those requirements. It can be achieved through Digital Twin (DT). 

  • The concept of an Asset Administration Shell (AAS) proposed by Plattform Industrie 4.0 is used to realize DT in a standard manner. This project proposed 3D computer simulation technology as a dynamic digital twin by following Reference Architecture Model Industrie 4.0 (RAMI 4.0) based on AAS Framework. 

  • The proposed concept enables DT to do dynamic monitoring, optimization, and direct controlling. To support communication between assets, OPC Unified Architecture (OPC UA) and Automation Markup Language (AutomationML) are determined. 

  • As a result of the demonstration, simulation-based optimization is done for multi-objectives and can find the optimum capacity of each AGV. Based on these capabilities, industry 4.0 scenarios can be integrated systematically and comprehensively.

• SHARED DATA/PROGRAMS/PAPER:

  • The paper is under review.
