貌似自己写的很多错啊...先谢过了!

再问： 不是吧，mcm1988B题啊！网上一搜就出来原题了，原题中有图表，不好往这里贴。用lingo该咋写，我们老师是用lindo写的，我感觉他那种写法效率不高。。。麻烦大神帮我用lingo写个。真心感谢！
再答： model: Title: train problem; sets:huowu/1..7/:t,w,k; train/1..2/:x; link(huowu,train):h,num; endsets data: t=48.7,52.0,61.3,72.0,48.7,52.0,64.0; w=2000,3000,1000,500,4000,2000,1000; k=8,7,9,6,6,4,3; l=1020; we=40000; enddata [OBJ] min=2*l-@sum(link(i,j):h(i,j)*t(i)*num(i,j)); @for(huowu(i):@sum(link(i,j):h(i,j)*num(i,j))
