Aspects of Measuring and Evaluating the Integration Status of a (Sub-)System at Runtime

Abstract

The basic idea of self-improving system integration (SISSY) is that the system itself autonomously decides about its own integration status and combines this maintenance with mechanisms to optimise it. Such an approach requires a quantifiable basis of all necessary system attributes and a set of goal functions defining desired solutions. In this article, we define a basic model of such a SISSY system and use this as basis to revisit possible aspects for measuring and evaluating the integration status. Different assessment criteria are suggested, based on performance, cost, security, behaviour, and more.
