Fire Safety Representation of City Facilities by Colored Face Graph

Use of Face Graphs to Categorize City Facilities

抄録

Categorization of city facilities such as theaters, hospitals, bars, hotels, department stores, and railway stations, is dealt with in this paper by using 24 fire-safety-related items evaluated by experts in this field. The data was qualitative - e.g., excellent, good, fair, poor, or bad - for each item and represented graphically by colored face graphs for each facitity. Visual discrimination of these faces into groups yielded a good categorization for fire safety evaluation of city facilities and good agreement with the results obtained through numerical cluster analysis.
