A dynamic vague multiple attribute decision-making method for emergency capability assessment

In order to assess the emergency capability of emergency departments dynamically, this paper introduces a dynamic vague multiple attribute decision-making (DV-MADM) method where all assessment values are represented by vague values. Firstly, the method utilizes the dynamic vague weighted averaging (DVWA) operator to aggregate the original assessment information collected at different periods into the complex assessment information. Secondly, the VIsekriterijumska optimizacija i KOmpromisno Resenje (VIKOR) is modified and developed to solve the complex assessment information. Finally, the emergency departments are ranked according to the ascending orders of S, R and Q values and the best department is selected. A numerical example is used to determine the effectiveness and feasibility of the proposed method.
