The formal representation and capturing of uncertainty knowledge are always essential but difficult. Typically, the uncertainties due to incompleteness and inaccuracies of model information in engineering design necessitate the designing of robust decision workflows to improve the quality of process/product in variations. This requests extending a designer's abilities in managing various uncertainties in system design and making decisions that are robust, flexible, and comprehensive. To enable the management of various uncertainties, in this paper, we propose an ontology for robust design and a template-based ontological method that is employed to design decision workflows. We achieve the aforementioned goals through the identification of: (1) procedural knowledge – defining a procedure of designing robust decision workflows, including the sequence of activities, to determine the right combination of design information for a specific type of uncertainty, and (2) declarative knowledge – developing a frame-based ontology for the formal representation of tacit knowledge to capture and document the re-usable information of a robust design by utilising the process templates. We demonstrate the efficacy by carrying out the robust design of the hot rod rolling process based on the analysis and synthesis of the processing-microstructure (cooling module) and the microstructure-mechanical (rod module) simulation models.

基于本体的不确定性管理方法在设计鲁棒的决策工作流程中

不确定性知识的形式化表示和捕获总是必不可少但也很困难。通常,由于工程设计中模型信息的不完整和不准确导致的不确定性需要设计稳健的决策工作流程,以提高变化中的过程/产品的质量。这要求扩展设计人员在管理系统设计中的各种不确定性和做出稳健、灵活和全面的决策方面的能力。为了能够管理各种不确定性,在本文中,我们提出了稳健设计的本体和用于设计决策工作流的基于模板的本体方法。我们通过识别以下内容来实现上述目标:(1)程序知识——定义设计稳健决策工作流程的程序,包括活动序列,以确定特定类型不确定性的设计信息的正确组合,以及 (2) 声明性知识——开发基于框架的本体,用于隐性知识的形式表示,以捕获和记录可重用信息使用过程模板进行稳健的设计。我们通过基于加工微观结构(冷却模块)和微观结构力学(棒材模块)模拟模型的分析和综合,对热棒材轧制工艺进行稳健设计来证明其功效。(2) 声明性知识——开发一个基于框架的本体,用于隐性知识的形式表示,通过利用过程模板来捕获和记录稳健设计的可重用信息。我们通过基于加工微观结构(冷却模块)和微观结构力学(棒材模块)模拟模型的分析和综合,对热棒材轧制工艺进行稳健设计来证明其功效。(2) 声明性知识——开发一个基于框架的本体,用于隐性知识的形式表示,通过利用过程模板来捕获和记录稳健设计的可重用信息。我们通过基于加工微观结构(冷却模块)和微观结构力学(棒材模块)模拟模型的分析和综合,对热棒材轧制工艺进行稳健设计来证明其功效。
