关于lingo优化时出现的优化值不确定的问题

sets:
times/1,2,3,4,5/:need,t,total;
style/1,2,3/:value,blow,high,begin,a,num;
links(times,style):x,y,z;
endsets

    @for(times(i)：@sum(style(j):x(i,j)*y(i,j)))>=1.13*need(i));   !第一种方式；

    <A href="mailto:!@for(times(i)：@sum(style(j):x(i,j)*y(i,j)))" target="_blank">!@for(times(i)：@sum(style(j):x(i,j)*y(i,j)))>=need(i));     !第二种
    <A href="mailto:!@for(times(i)：@sum(style(j):x(i,j)*high(j)))" target="_blank">!@for(times(i)：@sum(style(j):x(i,j)*high(j)))>=1.13*need(i));    ! 方式

data:
value=2 1.30 3;
blow=850,1250,1500;
high=2000,1750,4000;
begin=1000,2600,3000;
a=2000,1000,500;
num=12,10,5;
need=15000 30000 25000 40000 27000;
t=6 3 6 3 6;
enddata

这是我编写的程序，不知道为什么在运行第一种方式的时候，他出现的值是稳定，但是当运行第二种的时候，优化值就会出现不同的多个值，这样子是不是正确呢，希望路过的大虾拔刀相助！！！万分感谢！！

<A href=.....  那句是什么意思啊

这程序能不能在句子后解释一下啊

lsj5432723

这时难看懂
