Digital Twins and their significance in Engineering Asset Management

Developing digital replica of complex systems for the purpose of decision making is an emerging concept in various subject domains. This paper surveys the history, state of development, characteristics and key features from multiple domains and their suitability for life cycle decision making of engineered assets. The review also explores the current state of knowledge, level of abstraction and precision, limitations, benefits and future opportunities in a service-oriented application for prognostic decision making.
