The optimal models and algorithms for making up pairs and non-pairs locomotive turn-around diagram are given out. Specially, a more efficient way to consider both the optimum and the equilibrium of this problem is also presented as follows: at first formulate the network flow model of this problem and solve it by the method of the minimal cost flow and then use the labeling method to readjust the solution.

对成对和不成对机车周转图编制问题进行了探讨，给出了其最优配置的数学模型和算法；在此基础上，提出了把均衡性与最优化综合考虑的不成对机车周转图的改进算法——首先建立网络流模型用最小费用流算法求得问题的初始最优解，然后用标记法对该解进行调整，使其在最优的基础上达到均衡。

That is, network coding has a larger rate region in a multicast CIOQ switch. Moreover, the graph-theoretic characterization was given out. With the concepts of stable set polytope from the enhanced conflict graph, it is pointed out that computing the offline schedule can be reduced to certain graph coloring problems.

文章证明了对一个流中的分组进行线性网络编码可以承载不允许网络编码时不能够承载的交换流量模式，也就是说，网络编码允许CIOQ交换结构在实现组播服务时有更大的速率区域，并给出了基于图论方法的描述。
