A Note on Using Test Number Distinguishing Optimal Solution in Transportation Problems

求解运输问题的表上作业法中一般用检验数判别可行解是否为最优解,但此方法并不适用于判别非基本最优解和部分基本最优解.

In the table-working method of transportation problems,test number is generally used to distinguish whether the feasible solution is the optimal solution,but this method isn＇t suitable for distinguishing non-basic optimal solution and partial basic optimal solution.
