帮忙看看这个代码有什么问题吧，输出的结果很奇怪

model:
sets:
  distribution/1..71/:k;
  demandplace/1..71/:d,b;
  cost(distribution,demandplace):cij,x;
endsets
data:
b,d,k,cij=@ole('D:\data2.xls');
enddata
[obj]min=@sum(cost(i,j):0.035*cij(i,j)*d(j)*x(i,j))
        +@sum(cost:x*k*b)
        +@sum(demandplace(j):3.125*d)+750000*@sum(distribution(i):@sign(@sum(demandplace(j):x(i,j))-2)+1);
@for(demandplace(j):@sum(distribution(i):x(i,j))=1);
@for(cost:@bin(x));

end

把数据表也发上来才能运行
