Brogan, David0426971Our world is increasingly instrumented and networked with remote sensing and computational devices, creating new opportunities for enhanced analysis and prediction. Exploitation of these opportunities requires dynamic, data-driven application systems (DDDAS) composed from complex combinations of sensors, networks, computational resources, simulation software, and humans-in-the-loop. The project will develop an end-to-end DDDAS simulation design methodology and transformation process that will improve the potential for simulations to adapt to the dynamic composition of computational and data resources at run time. The project will deploy a crosscutting approach to simulation design and transformation called .COERCE.. COERCE addresses the immediate challenges of making simulations work most effectively in existing dynamic, data-driven application systems. COERCE is both coercibility (a property of simulations) and coercion (a process). Coercibility addresses the practices and methods whereby designer knowledge about how a simulation can be transformed is captured (possibly in simulation language constructs) to support future coercion. Coercibility provides for the capture and representation of simulation properties. Coercion is the process of transforming a simulation using a human-controlled mix of code modification and semi-automated analysis and optimization to meet a specific set of requirements, possibly differing from those for which the simulation was originally designed. Through coercion, preexisting (legacy) simulations can be transformed to adapt to new or missing data sources, to change fidelity, and to change their roles in a larger data-driven system.

Brogan，David0426971our World越来越多地使用遥感和计算设备进行了启动和联网，为增强分析和预测创造了新的机会。 对这些机会的开发需要动态的，数据驱动的应用系统（DDDA），该系统由传感器，网络，计算资源，仿真软件和人类的复杂组合组成。 该项目将开发端到端DDDAS仿真设计方法和转换过程，该过程将提高模拟在运行时适应计算和数据资源的动态组成的潜力。 该项目将在仿真设计和转换中部署一种称为.coerce的横切方法。Cocer。解决使模拟在现有的动态，数据驱动的应用程序系统中最有效地工作的近期挑战。 胁迫既具有可矫正性（模拟的属性）和强制性（一个过程）。 可矫正性解决了设计师有关如何转换模拟的知识（可能在模拟语言构造中）以支持未来胁迫的实践和方法。 可矫正性提供了模拟属性的捕获和表示。 胁迫是使用代码修改和半自动分析和优化的人类控制的组合来转换仿真的过程，以满足一组特定的要求，可能与最初设计的模拟的要求有所不同。 通过胁迫，可以转换前（遗产）模拟以适应新的或缺少的数据源，更改忠诚度并改变其在较大数据驱动的系统中的角色。
