For the position in the fire scene The flammability value of the object. The higher the value, the more flammable the object. For time Position in the fire scene Oxygen concentration, For the position in the fire scene The activation energy of an object at , which means the energy required for the object to start burning. is the gas constant, is the maximum fire suppression intensity of damage control equipment. For time Position in the fire scene The fire suppression strength of the damage control equipment, is the second adjustment factor for temperature; time Position in the fire scene Temperature include: ， in, is the initial temperature, is the time adjustment factor, is the temperature fluctuation amplitude, The temperature along the fire scene The wave number in the axial direction indicates the temperature in the fire scene along The propagation frequency in the axial direction, The temperature along the fire scene The wave number in the axial direction indicates the temperature in the fire scene along The propagation frequency in the axial direction, The temperature along the fire scene The wave number in the axial direction indicates the temperature in the fire scene along The propagation frequency in the axial direction; The object structure damage model includes: ， in, For time Position in the fire scene The structural damage degree of the object at is the adjustment factor for the flammability value, For the Acting in the direction The stress tensor on a surface, is the adjustment factor of the stress tensor, is the stress tensor limit value of the object, is the damage activation energy of the object, which means the energy required for the object to start being damaged. is the adjustment factor of the stress tensor gradient, For the Acting in the direction The stress tensor gradient on a surface is This is the correction item for damage control by damage control equipment; A damage control equipment interaction model is set up, and combined with the fire extinguishing instructions issued by the user to the damage control equipment, the fire intensity, the degree of damage to objects and the utilization of damage control equipment resources are minimized.
