假設生產甲X噸,乙生產Y噸,根據題干給出的約束條件得到:
X+2≤86
5X+3≤150
取邊界值得X=6,Y=40,最大利潤=3*6+4*40=178,即最大利潤為178,生產甲的數量是6噸。

該題為最短物質運輸時間問題,軟考大部分這類題目均可以通過找對應的最小數來解決。
第一步:先在表格中找最小的對應關系:
A運輸到甲:17小時;
B運輸到?。?0小時;
C運輸到丙:18小時;
D運輸到丙或?。?9小時;
第二步:判別是否有能替換的關系
上一步之后,由于乙城市沒有送,可以找運輸到乙時間最短的C送,然后丙由D送;
第三步:總結最終方案
A運輸到甲:17小時;
B運輸到?。?0小時;
C運輸到乙:19小時;
D運輸到丙:19小時;
則最短的運輸時間為:17+20+19+19=75小時。
