System Architecture Analysis with Network Index in MBSE Approach -Application to Smart Interactive Service with Digital Health Modeling-

Abstract

In recent years, systems have become large scale and complex due to the development of Internet of Things (IoT). Therefore, it becomes difficult to understand the influence of component specification changes that occur during the system development stage. Thus we focus on Model-Based Systems Engineering (MBSE), which is capable of expressing hierarchical structure and overviewing information. In this paper, we propose a method for analyzing the influence on the smart interactive service with digital health modeling caused by changes in system elements using index of network theory. As a conclusion, we clarified the degree of influence on the whole system caused by changing the specification of each component with using eigenvector centrality, which is one of the network indices.
