To facilitate system architecture development using DoDAF, we propose an architecture development methodology based on DoDAF 2.0 in this paper. First, based on experiences in practice, gaps between Operational Viewpoint (OV), Capability Viewpoint (CV) and System/Service Viewpoint (SV/SvcV) are analyzed. Second, to bridge the gaps, two architecture viewpoints, i.e. Information activity Viewpoint (IaV)...
This paper proposes an approach to construct effectiveness evaluation model semi-automatically based on system architecture such as Department of Defense Architecture Framework (DoDAF). The effectiveness evaluation index system is firstly generated based on architecture models including Capability Dependencies (CV-4), Capability to Operational Activities Mapping (CV-6), Operational Activity to Systems...
In the model driven system engineering, architecture plays an important role in the quality of the developed complex system. In some extend, the quality of the architecture determines the developed system's quality. The system's architecture is usually described from different views, including static views and dynamic views, like DoDAF (Department of Defense Architecture). Then how to ensure the consistency...
To reduce the cost and risk of the development of system of systems (SoS) by pre-evaluation before the SoS is built, a model-driven approach is proposed to evaluate the SoS based on its architecture, especially focused on measures of performance and effectiveness. In order to implement the pre-evaluation, the system architecture needs to be transformed to the simulation model of the system under the...
The execution of web applications always involves many levels (Operating system, Java virtual machine, Web server, Database server, application itself). Each level can produce its corresponding logs, which record the information of the level's running state and history. Based on the multi-level logs generated by the running web systems, this paper proposes a comprehensive method to evaluate and analyze...
