The construction of effectiveness evaluation model based on system architecture

摘要

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 Traceability Matrix (SV-5b) and System Measures Matrix (SV-7) in the DoDAF, using the transformation technology QVT. Then the effectiveness calculation model, which is based on analytic hierarchy process (AHP), is semi-automatically generated based on the evaluation tool developed by the authors' team. Based on the effectiveness evaluation index system and the calculation model, the effectiveness of the system described in the architecture can be evaluated in the supporting of the corresponding data, which can be from simulation results or experts. Because the effectiveness evaluation model is constructed based on the system architecture, The proposed approach can ensure that the constructed effectiveness evaluation model including the index system and the calculation model has its source and is objective, distinguishing from experience or emotion. Besides, the proposed approach can improve the efficiency and decrease the mistakes during the process of constructing effectiveness model.
