Kunii and Yoichi Seki, "A case study of component configuration information management in manufacturing using a position information formula and the processing map of the cellular data system", the 2015 International Conference on Cyberworlds 2015 (Cyberworlds 2015, 7-9 October, Gotland, Sweden), pp.14-pp.21, IEEE Computer Society Press, 2015.

In the era of cloud computing, data is processed in a Cloud, and data and its dependencies between systems or functions progress and change constantly within the cloud, as a user's requirements change. Such information worlds are called cyber worlds. We need a more powerful mathematical background which can model the cyber worlds as they are, and a finite automaton for implementing it as a computer system. We consider the Incrementally Modular Abstraction Hierarchy (IMAH) to be most appropriate to model the cyber worlds. We have developed a data processing system called the Cellular Data System (CDS) implementing IMAH. In this paper, we introduce a position information formula, which identifies the relative position of a specified factor in a formula, and its processing map, which obtains a sub-formula using the position information formula in CDS. This function is inevitable in the development of business applications where data have a fixed form, such as parts list data. We show the effectiveness of the formula by taking up a case study of component configuration information management in car manufacturing. In the case study, it is demonstrated that design component configuration information and manufacturring component configuration information are consistently managed even when component configuration frequently changes.
