UMLによる組込みシステム記述言語SysMLのモデル化の検討

摘要

In this study, we modeled the correspondence of SysML and UML as an example of the conversion method to UML from SysML. Our proposal defined that the correspondence in the policy not losing the informa tion of SysML in UML. In addition the concept was expressed so that the concept with each diagram of SysML included might not change in a diagram of UML. When I adapted the Rain Sensing Wiper system for this proposal, we found that the conversion was performed certainly. However, it followed that a difference between SysML nota tion and the UML notation was accompanied with complexity in a UML diagram. In embedded system design, this shows that the notation of UML is insufficient and that the mutual complement of SysML and UML is necessary.%本研究では，SysMLからUMLへの変換方法の一例として，SysMLからUMLへの対応付けをモデル化した.本提案では，UMLにおいてSysMLの情報が失われないことを方針に定義した．また，SysMLの各図が持つ概念がUMLの図において変わってしまわないように表現した．本提案を雨滴検知システムに適応したところ，変換を確実に行なえることがわかった．しかし，SysML表記とUML表記での違いがUML記述に煩雑さを伴う結果となった．このことは組込みシステム設計においてUMLでは不足している表記が多く，SysMLとUMLの相互補完の必要性を示している．
