System of Systems Architecture Prioritization Using A Comprehensive Evaluation Framework

The evaluation of SoS architecture can ensure the fulfillment of the stakeholder needs and the SoS requirements, promoting the right architecture decisions from numerous alternative architectures. However, there is still a research gap that a comprehensive evaluation framework considering a series of vital evaluation criteria to prioritize SoS architecture have not been established. In this paper, eight attributes were selected as the criteria, and a combined fuzzy Decision-making and Trial Evaluation Laboratory (DEMATEL) and the fuzzy Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method were used for SoS architecture prioritization. A hypothetical case demonstrates the effectiveness of the proposed evaluation framework, and shows that resilience and robustness are the most important criteria to improve the overall performance of SoS architecture.
