Due to the limitation of the condition such as funds, most of the cities and small towns are still using traditional fire alarm and fire control scheduling model, this model of a series of defects and the insufficiency, such as fewer people police what insufficient contradiction is outstanding, the one-sided emphasis on fire control communication command system construction, has neglected the fire digital simulation and fire command decision making the organic combination of the fire command decision depends mainly on the commander's subjective judgment and experience, due to the effective information is difficult to obtain, easy to cause fire decision-making mistakes. The fire happened every process and link all and space geographic factors closely related, if has the time and space distribution, intensity and frequency, social economic vulnerability, loss evaluation, fire emergency plan etc. And fire command decision measurement is set troops fighting collective behavior, according to the complicated disaster, selecting the best fire battle plan. Therefore, the integrated use of fire science, geographic information system and so on many kinds of subject technology used for fire emergency command decision, the establishment of an agile inquires the all kinds of relevant information, advance fire analysis model, provides a quick support scheme and aid decision making fire mode analysis and emergency decision making system, and use of the limited manpower and material resources maximize saves the efficiency, reduce the decision-making deviation, reduce fire loss, has become the new period "digital fire" the development direction and trend.
