| Title: A decision making method based on interval type-2 fuzzy sets: an approach for ambulance location preference | |
| Abstract: Selecting the best solution to deploy an ambulance in a strategic location is of the important variables that need to be accounted for improving the emergency medical services. The selection necessitates both quantitative and qualitative analysis. Fuzzy set based approach is one of the well-known theories that help decision makers to handle fuzziness, uncertainty in decision making and vagueness of information. This paper proposes another decision making method of Interval Type-2 Fuzzy Simple Additive Weighting (IT2 FSAW) as to deal with uncertainty and vagueness. The new IT2 FSAW is applied to create a preference in ambulance location. The decision making framework defines four criteria and five alternatives of ambulance location preference. Four experts attached to a Malaysian government hospital and a university medical center were interviewed to provide linguistic evaluation preceding analyzing with the new IT2 FSAW. Implementation of the proposed method in the case of ambulance location preference suggests that the ‘road network’ is the best alternative for ambulance location. The results indicate that the proposed method offers a consensus solution for handling the vague and qualitative criteria of ambulance location preference. | |
