What is a Simulation-Based Digital Twin?

• Connected, virtual replica of an in-service physical asset in the form of anintegrated multi-domain system simulation that mirrors the life and experience ofthe asset.

• Enables predictive and prescriptive maintenance and optimizes industrial assetmanagement.
