消防部门在接到森林火情后,由于无法精确得知森林火场的风速、气温、湿度、火势蔓延程度等相关信息,加之时差现象,致使消防部门派出的救援人数有可能过少,此时就必须进行增援.本文在无风、有风的情况下,建立森林损失费用与救援费用最小的优化模型,确定了最佳增援人数. After receiving fire from the forest fire department, the fire department can not accurately know the wind speed, temperature, humidity, spread of fire and other related information, combined with the time difference, resulting in the fire department dispatched the rescue may be too small, then It is necessary to reinforce.This paper establishes an optimization model with the least cost of forest loss and rescue cost in the absence of wind and wind, and determines the best number of reinforcements.
