GOALI/IUCP: Concurrent Optimization-Based Design of Multi-Component Systems with Multiple Views

这个项目是为了开发一个决策支持工具，用于多组件系统的并行设计，如电动工具，这些系统受到多个视图的影响，如设计、制造和营销考虑。开发的数字工具将确定产品系统的设计属性，从而在给定产品市场需求的情况下，实现设计的最高可能效用。产品设计在系统层面的效用将由单一的效用(或目标)函数来建模。这一功能的制定将满足企业的目标。系统级的目标函数将是子系统(或部件)级的目标的函数。将根据性能、质量和成本指标制定子系统级别的目标函数。将施加适当的限制。该模型将允许最高级别的决策者在系统级别进行交互和权衡探索，并允许决策者在子系统级别进行探索。将该模型应用到电动工具的设计中，以获得折衷的协同设计解决方案。如果成功，这项研究的结果将提高工程设计过程中的并发性，缩短产品设计开发时间，降低成本，从而使美国行业在全球市场上更具竞争力。

This project is for the development of a decision support tool for concurrent design of multi-component systems, such as power tools, that are subject to multiple views, such as design, manufacturing, and marketing considerations. The developed numerical tool will determine design attributes of a product system such that, given the product market demand, the highest possible utility of the design is achieved. The utility of the product design at the system's level will be modeled by a single utility (or objective) function. This function will be formulated to meet the goals of a business. The objective function at the systems level will be a function of the objectives at the subsystems (or components) level. The objective functions at the subsystems level will be formulated based on performance, quality, and cost metrics. Appropriate constraints will be imposed. The model will allow interactions and tradeoff explorations by a top-level decision maker, at the system-level, and by decision makers at the subsystems level. An application of the model to the design of a power tool will be demonstrated in order to obtain a compromise collaborative design solution. If successful, the results of this research will lead to increased level of concurrency in the engineering design process, reduce product design development time, reduce cost, and as a result make the US industry more competitive in the global marketplace.
