System design and engineering trade-off analytics: State of the published practice

System design and engineering involves making decisions involving multiple stakeholders with diverse and, potentially conflicting, objectives. As more and more data become available with digital engineering, big data, and data science, trade-off analytics will be an increasing important tool for engineers. We used a structured literature survey with Web of Science key words and bibliographic, categorical, and bibliometric analysis to answer 14 research questions. As our literature survey demonstrates, trade-off analysis can be found in almost every engineering domain. We provide several insights from the literature survey for educators and practitioners.
