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，David0426971我们的世界越来越多地通过遥感和计算设备进行仪器化和网络化，为增强分析和预测创造了新的机会。 要利用这些机会，需要由传感器、网络、计算资源、模拟软件和人机交互的复杂组合组成的动态数据驱动应用系统 (DDDAS)。 该项目将开发端到端 DDDAS 仿真设计方法和转换过程，以提高仿真适应运行时计算和数据资源动态组成的潜力。 该项目将部署一种名为 .COERCE 的横切方法进行模拟设计和转换。COERCE 解决了使模拟在现有动态、数据驱动的应用系统中最有效地工作的直接挑战。 COERCE 既是 coercibility（模拟的属性）又是 coercion（过程）。 强制性涉及实践和方法，通过这些实践和方法，设计师可以捕获有关如何转换模拟的知识（可能在模拟语言构造中）以支持未来的强制。 可强制性提供了模拟属性的捕获和表示。 强制是使用人为控制的代码修改和半自动分析与优化组合来转换模拟的过程，以满足一组特定的要求，这些要求可能与模拟最初设计的要求不同。 通过强制，可以转换预先存在的（遗留）模拟以适应新的或丢失的数据源，改变保真度，并改变它们在更大的数据驱动系统中的角色。
