飞行管理 程序
{:soso__16982562632156684720_3:} 谁有95年建模B题飞行管理的相关程序啊？？？急求！！！！！！ 百度上有相关论文，但是没有程序也白搭，哪位大神有啊？？？？{:3_59:}{:3_59:}{:3_59:} 这个约束条件可以写成什么样的程序呢？急求！！！ 大神们！！！百度里给的那种答案，飞行管理模型中这个怎么求啊？只要给个最终结果就好了！！！ 大神~~~~~~们~~~~~ 附1 的计算（lingo编程）:model:

附2 的计算（matlab编程）:
a=;b=;
x=a+b*i;
c=*pi/180;
v=exp(i*c);
k=length(a);
for n=1:k
for m=1:k
cita(n,m)=(angle(v(n)-v(m))-angle(x(m)-x(n)))*180/pi;
end
end

附3 最优解的计算lingo程序：
因与在lingo编程里不易区分，因此将表示为beita
model:
sets:
plane/1..6/:cita;
link(plane,plane):alpha,beta;
endsets
min=@sum(plane:@abs(cita));
@for(plane(n):
@bnd(-30,cita(n),30);
);
@for(link(n,m)|n#ne#m:
@abs(beta(n,m)+0.5*cita(n)+0.5*cita(m))
>alpha(n,m);
);
data:
alpha=0.000000,5.391190,32.230953,5.091816,20.963361,2.234507,

大神，还在不？我想请教一下，任意两架飞机相对飞行速度与飞机质点连线夹角有程序么？有结果么？？？还有刚才程序都是求什么的？能简单说明下么？？ 上面程序的ALPHA，你自己看下程序。只是给你提示，每个人设的都不一样，你要自己编自己的公式呢。 angler啊 发表于 2011-8-9 22:39 static/image/common/back.gif
