A Study on Decision Making Structure Modeling in Design and Manufacturing

本研究项目的目的是：1)提出一种形式化的方法来建模设计和制造组织中观察到的决策结构；2)利用信息技术来支持决策建模。两年的研究产生了如下有趣的结果：1.提出了一种新的形式化建模方法“COMPLE”。该方法处理各种建模因素，如组织、时间、任务、流程等。开发了基于COMPLE的计算机辅助建模系统DemoS3。DemoS3收集有关决策活动的碎片化数据，并将其系统化到通过VRML通过图形用户界面观察的数据库中。该系统可以帮助人类用户以直观的方式理解决策结构。除了对建模的支持外，还研究了业务流程重组对决策结构分析的支持。以创新汽车研制的设计过程和航天器出事问题的解决为例，应用Scope和DemoS3软件进行了实例分析。应用结果表明，所提出的方法和系统对决策结构的分析是有效的，为工业企业现场组织任务处理提供了一种形式化的建模和分析方法，为工程应用开辟了新的领域。

The aims of this research project are 1) to propose a formal method of modeling decision making structures observed in organizations for design and manufacturing, and 2) to support decision making modeling by information technology. Two years research produced interesting results as follows.1. A formal modeling method named "ScoPy" was newly proposed. This method deals with various modeling factors such as organizations, time, tasks, processes, and so on.2. A computer supported modeling system named "DemoS3" was developed based on ScoPy. DemoS3 collects fragmented data about decision making activities and systhematizes them into database observed through GUI with VRML.The system can helps human users to understand decision making structure in an intuitive way.3. In addition to the support of modeling, the support of analyzing decision making structure was investigated for BPR.4. ScoPy and DemoS3 were applied to two cases : design process of innovative car development and problem solving for space ship in trouble. The results of application showed that proposed method and systems were effective in analyzing decision making structure.These research results shows that proposed method gives a formal modeling and analyzing method to the field organizational task processing in industrial companies and explore a new application field of engineering.
