Control of identification area of structured identifier by set theory and connection techniques for modularized facility management functions

This paper is to propose an information management technique, which is easy to understand by humans and easy to utile analysis program, in order to manage complicated machines and facilities. To manage the facilities, we show a modeling that partly defines the structure of the facilities by set theory, further defines the requirements for joining the subset of structured identifiers on consistency. In verification of the proposal and programming method, we show how to control the amount of information of structured identifier as uniquely identifier. As a result, we show our proposal is useful to address real problems in management software.
