摘要
数字新时代各种事物甚至整个世界都可以被数字化为模型,进行各种目的的仿真活动,仿真活动的结果可以为各种决策提供智能化支持。数字孪生是建模与仿真在数字新时代应用的重要形式,已广泛应用于智能制造、智能工厂、智能建筑、智慧城市等诸多领域,显示出强大生命力,其下一步的发展方向是全面的数字工程。回顾数字孪生技术发展的历史,分析其现状和发展前景。介绍美军最新发布《数字工程战略》总体情况,提出数字新时代建模与仿真面临的机遇与挑战。
In the digital new era, all kinds of things and even the whole world can be digitized as a model.Simulation activities are conducted for various purposes, and the results can provide intelligent support for various decision-making. Digital twin is an important form of modeling and simulation application in the digital new era;it has been widely used in intelligent manufacturing, factories, buildings, smart cities and many other fields, showing a strong vitality;and its next step in the development direction is a comprehensive digital engineering. This paper reviews the history of the development of digital twin technology, analyzes its present situation and development prospects, and introduces the latest digital engineering strategy by the US Department of Defense. The opportunities and challenges faced by modeling and simulation of digital new era are put forward.
