 The term digital twin (sometimes used interchangeably with "synthetic environment") refers to an in-silico, computer simulated analogue to a real-world system. It is often used to describe computer simulations that mirror real-world biological systems, engineering projects (like jet engines, wind turbines, or vehicles), and architectural spaces, as well as individual factories and warehouses within larger supply chains.
 
-These "digital twins" (computer simulations) mirroring real-world counterparts can be placed in different virtual environments. This allows them to be inexpensively and safely examined under a wide range of conditions, often exceeding the number and range of environments affordable or practical to test in the physical, offline world.
+These "digital twins" (individual [entities](/glossary/entities) or entire [simulation models](/glossary/simulations)) mirroring real-world counterparts can be placed in different virtual environments, and have their parameters modified, to allow them to be inexpensively and safely examined under a wide range of conditions, often exceeding the number and range of environments affordable or practical to test in the physical, offline world.
 
-These simulations can also be used to generate [synthetic data](/glossary/synthetic-data-generation), perform low-cost tradespace analyses by modifying the digital system, and generate risk assessments by introducing simulated stochastic failures, among other things.

 All of these things can be fed back into the design of real-world systems, allowing them to be tested and improved online, before being built "in the real world" offline.
