The order of contacts to be called after an emergency situation - fuzzy multicriteria decision-making approach

This article deals with a quantitative support of decision-making in emergency management in order to select and organize emergency contacts according to their importance in relation to the possible consequences of an emergency situation. The decision support model is primarily designed to meet the needs of gas distribution dispatch centres. However, it can be applied to other sectors as well. With regard to the limited information that the employee of dispatch centre has available immediately after the emergency, the entire system is designed to work with vague input data. The used model is designed as a multicriteria decision-making model with fuzzy evaluation. The initial step of the process starts with the evaluation of the severity of all possible threats using fuzzy scale. For each threat a list of possible contacts with their importance is created. When an emergency situation occurs, the severity of the threats resulting from the current situation is evaluated on the fuzzy scale. Then the synthesis of the default and current evaluation of the threats importance take a place. After that the importance of individual contacts is calculated and lexicographically arranged. The summary of these steps is the overall functional model for the decision support.
