This research aims to develop the methodology and tool that help mapping between models of different applications, by utilizing the framework of STEP or the international standard for the representation of product model data. The research plans development of (a) the framework to help the interpretation, (b) methods to assist the mapping between different product models, (c) methods to assist the description of constraints to realize the information requirements and (d) methods to cope with instances for validation of the interpretation. Following are the results of this research;1. A tool is developed to help the mapping of models by using the concepts and technologies of STEP. It generates the mapping information in various forms based on the graphical input of mapping information between different models.2. Methods are developed to assist the mapping based on the analysis of the mapping between product models.3. Based on the comparison between EXPRESS-G diagram and UML class diagram, a graphical tool is developed for editing UML class diagram.4. Function is developed to display the cardinality along reference paths in order to assist the mapping between cardinality relations. It utilizes the comparison of cardinalities in product models.5. For the cases of structural mapping without constraints or branches of reference paths; codes of model conversion description' language EXPRESS-N are generated based on the mapping information acquired by. the tool. The generation method is validated by the conversion of data from STEP standard using a commercial conversion software based on EXPRESS-X.Results of the research contribute to facilitate the data exchange and sharing among different applications. 'Remaining issues -include the development of methods for advanced description method of constraints and handling of instances.

本研究的目的是开发的方法和工具，帮助不同的应用程序模型之间的映射，通过利用STEP的框架或国际标准的产品模型数据的表示。本研究计划发展（a）帮助解释的框架，（B）帮助不同产品模型之间映射的方法，（c）帮助描述约束以实现信息需求的方法，以及（d）科普解释验证实例的方法。以下是本研究的结果：1。利用STEP的概念和技术，开发了一个辅助模型映射的工具。通过图形化输入不同模型之间的映射信息，生成各种形式的映射信息.在分析产品模型间映射关系的基础上，提出了辅助映射的方法.在比较EXPRESS-G图和UML类图的基础上，开发了一个UML类图编辑工具.函数被开发来显示沿着引用路径的基数，以辅助基数关系之间的映射。它利用了产品模型中基数的比较.对于无约束、无参考路径分支的结构化映射，基于所获得的映射信息生成模型转换描述语言EXPRESS-N的代码。工具。通过使用基于EXPRESS-X的商业转换软件对STEP标准数据进行转换，验证了该生成方法的有效性。研究结果有助于不同应用之间的数据交换和共享。“剩余问题-包括制定高级描述方法、约束方法和处理实例。
