| 摘 要： | 本文对流向受限运输问题的求解作了进一步探讨。讨论了虚运价取适当值时,最优解中不含有非退化的限制配点,去掉模型中的某些约束条件不影响问题的可行解,并指出不改变运输问题最佳调运方案的前提下,使总运费下降的条件及方法.

A Further Study of Algorithm of Transportation Question for Restricted Flow Direction |
| |
| Abstract: | This paper taper further study to the algorithm of transportation question for restricted flow direction1. It discussed that the optimum solution does not contain non-degenerate restrict distribution point when a suitable value of imaginary transport price is taken and that it does not affect the feasible solution of the problem by removing some restricted condition of the model. Meanwhile, it points out the descent condition and method of total transportation expeses based on maintaining the optimum allocate and transpot plan. |
