The Phased Evaluation and Information Visualization of City Building Fire Hazards

The fire developing process was divided into four partial periods, and the influential factors of every partial period were analyzed. Combining the workers´ abilities and management conditions, the 3 evaluation model of building fire was made. Use the method of AHP to determine the degree of importance between factors of the peer grade, i.e. weight. The 3 level fuzzy comprehensive evaluation method was applied to evaluating the building fire hazard. Using modern computer technology VB6.0 and MapInfo, the visual information management system was constructed. The evaluation and classification of building fire hazards were made based on the basic data, and the result can be shown in the map at real-time. Taking the building A in Qingdao City as an example, the evaluation result was consistent with the practice. And the system can help to realize the visualization and dynamic management.
