Operational research in the time of COVID-19: The ‘science for better’ or worse in the absence of hard data1
探讨在COVID-19大流行期间，政策制定者如何利用社交媒体和快速市场调查等辅助数据做出决策，并质疑缺乏可靠硬数据时分析方法的有效性。
How can policymakers and planners make informed decisions during a pandemic? What kind of (big) data are needed, and who and when is supposed to provide these? With the Operational Research community unable to get hold of reliable hard data – especially during the pandemic, the solutions promoted from analytics seem questionable. We may have to employ instead auxiliary data from social media and rapid market surveys.
