A computer implemented method of determining a probability of a fire within one or more rooms of a building , the method comprising: determining a geometry of a room in response to a floor plan ; determining whether one or more articles are located within the room and a flammability of each of the one or more articles ; determining whether one or more hazards are located within the room ; determining a probability of a fire in the room in response to at least one or more articles which are located within the room , the flammability of each of the one or more articles , and the one or more hazards which are located within the room ; determining a geometry of a second room in response to the floor plan ; determining whether one or more articles are located within the second room and a flammability of each of the one or more articles ; determining whether one or more hazards are located within the second room; determining a probability of a fire in the second room in response to at least one or more articles located within the second room, the flammability of each of the one or more articles , and the one or more hazards which are located within the second room; adjusting the probability of a fire in the room in response to the probability of a fire in the second room; generating a dynamic fire threat input map of the room on a computing device that displays the probability of a fire in the room ; determining a location and a type of one or more evacuation points within the room ; determining an accessibility of each of the one or more evacuation points within the room automatically based on the type of evacuation point , the location of the evacuations point , and of any fire escape devices are required to be located proximate the evacuation point ; and displaying the accessibility of each of the one or more evacuation points on the dynamic fire threat input map . determining a geometry of a room in response to a floor plan ; determining whether one or more articles are located within the room and a flammability of each of the one or more articles ; determining whether one or more hazards are located within the room ; determining a probability of a fire in the room in response to at least one or more articles which are located within the room , the flammability of each of the one or more articles , and the one or more hazards which are located within the room ; determining a geometry of a second room in response to the floor plan ; determining whether one or more articles are located within the second room and a flammability of each of the one or more articles ; determining whether one or more hazards are located within the second room; determining a probability of a fire in the second room in response to at least one or more articles located within the second room, the flammability of each of the one or more articles , and the one or more hazards which are located within the second room; adjusting the probability of a fire in the room in response to the probability of a fire in the second room; generating a dynamic fire threat input map of the room on a computing device that displays the probability of a fire in the room ; determining a location and a type of one or more evacuation points within the room ; determining an accessibility of each of the one or more evacuation points within the room automatically based on the type of evacuation point , the location of the evacuations point , and of any fire escape devices are required to be located proximate the evacuation point ; and displaying the accessibility of each of the one or more evacuation points on the dynamic fire threat input map . <EOS>
