In [28], the author has proved the feasibility in mathematics. In this paper, we propose a direct sum decomposition algorithm of AFS structure based on the research in [28], which decomposes a complex AFS structure into several independent sub-AFS structures, thus the elements in the same sub-AFS structure are dependent on each other, the elements in the different sub-AFS structures are independent.

本文在文献[28]理论研究的基础上，具体提出了AFS结构直和分解算法，实现了把一个复杂的AFS结构划分为若干个相互独立的子AFS结构，使得同一个子AFS结构中的元素是相互关联的，而不同子AFS结构中的元素是相互独立的，即每个子AFS结构均是一个连通系统，从而有效地降低了分析AFS结构的难度。

If the vertex set of a graph can be partitioned into two disjoint nonempty sets V_(1) and V_(2), every vertex in V_(1) connects every vertex in V_(2) and there is no edge in V_(1) and V_(2), then we call this graph is a complete bipartite graph. If V_(1) contains m elements and V_(2) contains n elements, then we denote this complete bipartite graph K_.

当一个图中的点集合可以分成两个非空的集合V_(1)及V_(2)，若 V_(1)中的每一点都与V_(2)中的点有边相连，且在V_(1)及V_(2)中的点都没有边相连，则称此图为完全二分图；若 V_(1)中有m个点，V_(2)中有n个点，则此完全二分图记为K_。
