摘要
In a System of Systems (SoS) context, executable architecting plays a vital role in providing a holistic, integrated solution for evaluation of designed architecture. In this paper, we propose a unified executable architecting approach to SoS based on Discrete Event System Specification (DEVS) by enhancing DEVS Unified Process (DUNIP) from three perspectives. Firstly we introduce a generic process to capture the essentials for an executable architecture using SysML based on Department of Defense Architecture Framework;Secondly, We propose an extension of DEVS, called Scheduled Parallel DEVS to enhance its ability to describe complex behavior;and finally a corresponding modeling language is provided as transformation intermediary to realize automated transformation from SysML to DEVS. To demonstrate the applicability of this approach we introduce an illustrative case in an airport scenario.
