Abstract

In this paper, we will clarify the risk factors which lower the reliability and quality of a growing large scale- system when the system is modified. We will then examine the methods to eliminate or ease those risk factors, and propose adaptive assurance technology that can minimize the risk under restrictive conditions such as cost, resource, periods, etc. Furthermore, we will show the results of the application of adaptive assurance technology to a large-scale transport operation control system, proving that this technology is effective.
