随着TRIZ在研究和教育方面的日益发展，用户在尝试实践它时总是遇到困难，特别是对于最复杂的创造性问题解决工具之一，Su-Field分析，它用于分析和提高技术系统的效率。一般来说，利用苏场模型解决特定发明问题的过程包括：建立问题模型，将其映射到通用问题模型，根据相应的发明标准找到通用解决模型，最后在现实生活中建立和解释解决模型。作为苏场分析中最重要的阶段之一，最后一步通常是在物理效果指针的帮助下手动实现的，它将通用技术功能与特定应用程序和系统联系起来。应该选择适当的、与特定问题的上下文兼容的指针，以帮助用户实例化解决方案模型。然而，物理效果指针和具体问题是在不同的抽象层次上构建的，因此，对于给定的某个函数，用户很难在众多符合条件的物理效果指针中进行选择。提出了一种基于本体推理的物理效果指针的启发式使用方法。使用称为本体的形式化模型，可以形式化地定义关于模型和效果的概念，并对其应用逻辑推理。首先建立发明标准本体和物理效果本体来描述苏场分析过程，然后根据词汇词典、发明标准分析和物理效果建立逻辑推理规则。建立了基于WordNet的词汇词典，以改进对适当效果的选择。最后，实现本体推理，为用户提供启发式物理效果。最后用一个实例详细说明了该启发式过程。
While TRIZ is increasingly developing both in research and education, users always encounter difficulties in their attempts to practice it, especially for one of the most complicated inventive problem solving tools, the Su-Field analysis, which is used to analyze and improve the efficiency of a technical system. Generally, the process of using a Su-Field model to solve a specific inventive problem includes: building a Problem Model, mapping it to a Generic Problem Model, finding a Generic Solution Model based on the corresponding inventive standard and finally establishing and interpreting a Solution Model in real life. As one of the most important phases of the Su-Field analysis, the last step is normally implemented manually with the help of the pointers to physical effects, which link generic technical functions to specific applications and systems. The adequate pointer, compatible with the context of the specific problem, should be chosen to assist the users to instantiate the Solution Model. However, the pointers to physical effects and the specific problems are built at different levels of abstraction, so it is difficult for the users to choose among many eligible pointers to physical effects given a certain function. This paper proposes a heuristic method to use the pointers to physical effects based on ontology reasoning. The use of formal models, called ontologies, allows to formally define the concepts about the models and the effects and to apply logical reasoning on them. An inventive standards ontology and a physical effects ontology are firstly built to describe the process of Su- Field analysis, and then the logical reasoning rules are established according to a lexical dictionary, the analysis of the inventive standards and the physical effects. The lexical dictionary, based on WordNet, is built to improve the selection of the appropriate effect to apply. Finally, ontology reasoning is implemented to provide heuristic physical effects for the users. A case is used to show this heuristic process in detail.
