Urban Fire Risk Evaluation Based on 2-tuple AHP—Taking the 8th Division with Shihezi City for Example

摘要

The evaluation of urban fire risk is an important gist of scientific and effective urban firefighting management, planning and construction. In this study, taking the 8th division with Shihezi city (Shi-City) as an example, an evaluation index system of urban fire risk is first built through analyzing the influential factors of fire risk in urban areas, which contains four first-class indexes and twenty-two second-class indexes. Then, to overcome the weaknesses of the analytic hierarchy process (AHP), 2-tuple fuzzy linguistic representation model is incorporated into AHP to calculate the weights of indexes. After that, an urban fire risk evaluation model is proposed. Finally, the developed model is applied into the fire risk evaluation of Shi-City and the fire risk rating of Shi-City is derived as slightly higher than medium, which can offer significant guidance for fire control and safety management.
