求高手看看这一段lingo程序有什么错误。

求高手看看这一段lingo程序有什么错误。

格式有问题 要写max= 而不是max z=

model:
max=35*x11+12*x12+16*x13+38*x14+5*x15+2*x16+25*x21+8*x22+9*x23+24*x24+6*x25+8*x26+12*x31+8*x32+11*x33+27*x34+3*x35+2*x36+38*x41+15*x42+14*x43+39*x44+2*x45+9*x46+0*x51+9*x52+8*x53+25*x54+10*x55+5*x56+0*x61+0*x62+0*x63+14*x64+6*x65+7*x66;

中间有一个集名写错了 最后两句都有问题 倒数第二句不是等式或者不等式关系 最后一句里面的l用在下标里面是什么意思
sets:
jingdian/1..11/:c,t,l;
links(jingdian,jingdian):r,cc,tt;
endsets
