Engineering design processes that are dependent on Computer-Aided Engineering (CAE) tools commonly involve complex patterns of tasks, including concurrency and intertwined iterations. There are often inefficiencies and improvement opportunities in such processes, but it can be difficult to identify and evaluate them—partly because of the complex iteration patterns, and partly because process knowledge is usually tacit and often distributed among process participants so that it is difficult to appreciate the causes and effects of iteration in an integrated way. The Applied Signposting Model (ASM) was developed to address these issues during more than a decade of research and case studies in the aerospace sector. This article describes an evolved version of the ASM, called ASM2.0, alongside a detailed case to demonstrate its application to improve CAE-driven, iteration-intensive engineering design processes. A review of applications is also provided. A differentiating feature of ASM2.0 is that it integrates visually-familiar flowchart mapping with quantitative analysis of process performance, to enable the modelling of complex iteration patterns that are typical of engineering design practice.

通过使用 ASM2.0 模拟迭代影响来改进工程设计过程

依赖于计算机辅助工程 (CAE) 工具的工程设计过程通常涉及复杂的任务模式，包括并发和交织的迭代。此类流程通常存在低效率和改进机会，但可能难以识别和评估它们——部分原因是复杂的迭代模式，部分原因是流程知识通常是隐性的，并且经常分布在流程参与者之间，因此很难以综合的方式了解迭代的原因和影响。应用路标模型 (ASM) 旨在解决航空航天领域十多年的研究和案例研究中的这些问题。本文介绍了 ASM 的一个演进版本，称为 ASM2.0，以及一个详细的案例，以展示其在改进 CAE 驱动的、迭代密集型工程设计过程中的应用。还提供了对应用程序的审查。ASM2.0 的一个与众不同的特点是它将视觉上熟悉的流程图映射与过程性能的定量分析相结合，从而能够对工程设计实践中典型的复杂迭代模式进行建模。
