LINDO程序之中不能用 分号和除号所以你写的约束条件的最后两个式子是不对的，同时LINDO程序之中不能有括号！
程序如下：
max 3100x11+3100x12+3100x13+3800x21+3800x22+3800x23+3500x31+3500x32+3500x33+2850x41+2850x42+2850x43

2)x11+x12+x13<18
3)x21+x22+x23<15
4)x31+x32+x33<23
5)x41+x42+x43<12
6)x11+x21+x31+x41<10
7)x12+x22+x32+x42<16
8)x13+x23+x33+x43<8
9)480x11+650x21+580x31+390x41<6800
10)480x12+650x22+580x32+390x42<8700
11)480x13+650x23+580x33+390x43<5300
12)16x11+16x21+16x31+16x41-10x12-10x22-10x32-10x42=0
13)8x11+8x21+8x31+8x41-10x13-10x23-10x33-10x43=0
end
结果如下：
