Group decision‐making in an unconventional emergency situation using agile Delphi approach

This paper presents a group decision‐making approach for managing unconventional emergency situations using the internet. In unconventional emergency events, the expediency of developing a response strategy is of utmost importance in group decision‐making environment. The research of this paper aims to rapidly develop and execute the response approach to the unconventional emergency events. We develop an agile Delphi decision‐making platform based on ASP.NET. The platform proposed in the paper also provides the function of identifying risk preference and cognitive style of the decision‐making experts, which allows experts to conduct appropriate alternative portfolio and enables researchers to find a new combination of experts to make the decision‐making more efficient. This paper concludes with an empirical analysis in which the sedimentation event that occurred at Wuhan subway is illustrated using the proposed methodology.
