In this article, we suggest a group decision method within an integrated computational framework for decision policy. Based on a co-creation workflow, epidemiological estimates, and socioeconomic factors, decisions are considered in a multi-stakeholder, multi-criteria context to elicit attitudes, perceptions, and preferences of relevant stakeholder groups. The complete framework has been applied in Botswana, Romania, and Jordan to assess mitigation actions related to the Covid-19 pandemic in order to mobilize better response strategies for other relevant future scenarios, and potentially more serious pandemics and other hazardous events. The framework was recommended as best practice in the EU under the European Open Science Cloud EOSC, Covid-19 Fast Track Funding.
