Research on multiple-viewpoint business modeling for developing software supporting collaborative business

为了开发业务支持软件，我们必须对目标业务进行适当的建模。如果得到的模型是错误的，开发的软件将被丢弃，因为它没有用处。在小型开发中，模型只在开发人员的大脑中消失。然而，在大中型开发中，需要人员或用户对模型进行解释和理解，IDEF0就是一个典型的业务建模。IDEF0图表是用简单的符号绘制的，即使是初学者也很容易理解图表的内容。然而，要画出一个合适的IDEF0图并不容易。本研究利用用例图、状态变迁图、Petri网、ER模型、IDEF0图等多种图，建立了多种从多个视角分析业务的方法。具体地说，我们开发了以下方法：1)从用户界面生成IDEF0图，2)从IDEF0图生成ER模型，3)从Petri网生成IDEF0图，4)从用例图和状态转换图生成ER模型，5)从用例图和Petri网生成ER模型，6)支持基于精益方法的业务流程分析。此外，我们还开发了一个用于1)的支持工具的原型。下一步的研究是开发用于OUT方法的支持工具。由于我的分析师很难完美地使用各种图表和方法，我们需要一个集成的支持工具。

To develop business support software, we must properly model target business. If the resultant model is a wrong one, the developed software will be thrown away because it is of no use. In small development, the model only ousts in the developer's brain. However, in middle or large development, the model should be explained and understood by the personnel or the users.IDEF0 is a typical business modeling. An IDEF0 diagram is drawn in the simple notation, and even a beginner can easily understand the contents of a diagram. However, it is not easy to draw a proper IDEF0 diagram. Especially when the staffs with multiple roles work in collaboration, a diagram will become ambiguous with multiple viewpoints.In this research, we have established several methods to analyze business from multiple viewpoints, using various diagrams such as use case diagram, state transition diagram, Petri net, ER model, IDEF0 diagram, and so on. Concretely we have developed the methods 1)to generate an IDEF0 diagram from user interfaces, 2)to generate an ER model from an IDEF0 diagram, 3)generate an IDEF0 diagram from a Petri net, 4)to generate an ER model from a use case diagram and state transition diagrams, 5)to generate an ER model from a use case diagram and a Petri net, and 6)to support business process analysis based on the lean method. Moreover, we developed a prototype of the support tool for 1).The future research is to develop support tools for out methods. Because it is difficult for me analyst to use various diagrams and methods perfectly, we need an integrated support tool.
