基于计算机的模型和模拟是发达经济体指导复杂系统设计所需的重要技术。例如，城市化的发展将需要在未来20年内在全球投资数万亿美元，用于发展交通、水和能源等城市基础设施。这项投资的很大一部分是为了解决美国基础设施老化的问题。计算机模型和模拟对于指导主要城市的这种重新设计至关重要，以便提高可持续性和对自然和人为灾害的复原力。同样，建模和仿真是设计航空航天、制造业、物流和供应链、电信、计算机和信息系统、医疗保健、国防和国土安全等行业复杂系统的基本技术。然而，可靠的计算机模型和模拟的开发和使用今天是耗时和昂贵的。工程系统的复杂性和规模不断增加。建模和仿真技术的进步对于最大限度地提高基于计算机的工具的有效性，以设计未来所需的日益复杂的系统至关重要。此外，最近的技术进步，如云计算，新型计算机架构，大数据和物联网，需要在建模和仿真的新发展，以充分利用这些能力。该项目将召开一个研讨会，汇集来自不同学科的领先研究人员，以确定和阐明最重要的，有影响力的建模和仿真研究问题和必须解决的问题，以最大限度地发挥新的建模和仿真技术的影响。本次研讨会的成果将为未来的建模和仿真研究投资提供信息，并最终实现更有效、成本更低的工程复杂系统的创建。研讨会将讨论建模和仿真的关键主题领域。概念建模将被检查，以确定来自不同学科的个人团队如何才能最好地创建复杂系统的复杂，可靠的模型。先进的计算方法将研究的主题，如利用新的计算能力和技术。技术和方法来管理复杂系统的设计中的不确定性将得到解决。将探索启用和促进模型重用的方法，以加速和降低创建有效计算模型的成本。

Computer-based models and simulations are vital technologies needed in advanced economies to guide the design of complex systems. For example, increased urbanization will necessitate investments of trillions of dollars globally in the next two decades toward the development of urban infrastructures such as transportation, water, and energy. A significant portion of this investment is needed to address concerns regarding the aging infrastructure in the United States. Computer models and simulation are essential to guide this re-design of major cities in order to realize increased sustainability and resilience to natural and human-caused disasters. Similarly, modeling and simulation are essential technologies to design complex systems in industries such as aerospace, manufacturing, logistics and supply chains, telecommunications, computer and information systems, health care, defense, and homeland security, among others. However, the development and use of reliable computer models and simulations is today time consuming and expensive. Engineered systems are continually increasing in complexity and scale. Advances in modeling and simulation technologies are essential to maximize the effectiveness of computer-based tools to engineer the increasingly complex systems needed in the future. Further, recent technological advances such as cloud computing, novel computer architectures, big data, and the Internet of Things necessitate new developments in modeling and simulation to fully exploit these capabilities. This project will convene a workshop that brings together leading researchers from disparate disciplines to identify and articulate the most important, impactful modeling and simulation research problems and questions that must be addressed to maximize the impact of new modeling and simulation technologies. The results of this workshop will inform future research investments in modeling and simulation, and ultimately, enable the creation of more effective and less costly engineered, complex systems.The workshop will address key topical areas in modeling and simulation. Conceptual modeling will be examined to determine how teams of individuals from different disciplines can best create sophisticated, reliable models of complex systems. Advanced computational methods will examine topics such as exploitation of new computing capabilities and technologies. Techniques and methodologies to manage uncertainty in the design of complex systems will be addressed. Approaches to enable and facilitate model reuse will be explored to accelerate and reduce of cost of creating effective computational models.
