On this basis, in order to minimize the two objectives of the transport costs to model, to convert it into a network flow model with a stratified, with the minimum cost maximum flow algorithm.

在此基础上以运输成本最小化为二级目标建立模型，将其转化成带有分层的网络流模型，用最小费用最大流算法进行求解。

Then we construct a capacity cost network from the debt credit degree network. Finally, by applying minimum cost circulation flow problem, we give a polynomial algorithm for this model.

然后由债务信度网络构造了容量费用网络，利用最小费用循环流问题给出了该模型的一个多项式算法。
