LINDO程式之中不能用 分號和除號所以你寫的約束條件的最後兩個式子是不對的，同時LINDO程式之中不能有括號！

程式如下：

max 3100x11+3100x12+3100x13+3800x21+3800x22+3800x23+3500x31+3500x32+3500x33+2850x41+2850x42+2850x43

st

2)x11+x12+x13

3)x21+x22+x23

4)x31+x32+x33

5)x41+x42+x43

6)x11+x21+x31+x41

7)x12+x22+x32+x42

8)x13+x23+x33+x43

9)480x11+650x21+580x31+390x41

10)480x12+650x22+580x32+390x42

11)480x13+650x23+580x33+390x43

12)16x11+16x21+16x31+16x41-10x12-10x22-10x32-10x42=0

13)8x11+8x21+8x31+8x41-10x13-10x23-10x33-10x43=0

end

結果如下：
