A Reconfiguration Approach for Open Adaptive Systems-of-Systems

Abstract

The drive for digitalization in industry and transport results in an increasing application of cooperative systems that form adaptive system-of-systems. With reconfiguration these systems are able to change their behavior to react on internal changes and changes in their environment. In this paper, we present a novel service-oriented approach for decentralized reconfiguration within such systems-of-systems that specifically supports open adaptive systems-of-systems. We introduce the concept of strategy blueprints that define possible combinations of services provided by individual members of the system-of-systems. During reconfiguration, individual member systems evaluate all strategies that are instantiable under the given conditions, and select the one optimally fulfilling a set of predefined goals as the most appropriate target configuration. With this novel approach, we support flexible reconfiguration across the borders of individual member systems, and the inclusion of new member system types that provide service variants not yet known at design time of the reconfiguration algorithm.
