Fire risk evaluation device, fire risk evaluation method and program

摘要

Problem to be solved: to provide a fire risk evaluation apparatus, a fire risk evaluation method and a program for more appropriate evaluation of fire risk in consideration of uncertainty regarding fire.The risk evaluation device 10 isUncertainty distribution on peak value of heat generation rate during fire occurrenceAcquisition and acquisition of the uncertainty distribution of fire extinguishing time required for fire extinguishingBased on uncertainty distribution on peak valuesA calculation condition setting section for creating a behavior pattern of a plurality of heating speeds having a peak value of a predetermined rate of change in the behavior of the heating rate and theBased on the distance and behavior pattern of the target and fire sourceFor each behavior patternAn analysis method for calculating the uncertainty distribution of the event occurrence time, which is the time until the attention event occurs.Based on uncertainty distribution of event occurrence time and uncertainty distribution of extinction timeBy statistical processingThe probability that the extinction time is longer than the event generation time isThe probability calculation unit which is calculated as an event occurrence probability that an attention event occurs in the object of interest..Diagram
