图对同一个逻辑问题可有不同的表达方式。不同方式的图之间存在着逻辑同构变换问题。本文以计划网络从节点型向箭线型变换为实际背景,提出了网络结构的“节点、箭线子模”概念,建立了形成网络结构的计算机算法——逐节生长法,在若干工程应用中证明是正确的。这种方法改变了手工绘制箭线型初始网络图,相当程度取决于经验和技巧的状况,有利于网络计划技术的推广应用。同时,也对解决图论中的逻辑同构变换问题进行了探索。
Figure on the same logic problems can have different expressions. There is a logical isomorphism between different ways. In this paper, the planning network is changed from node type to arrow type to actual background, and the concept of “node, arrow line submodule” of network structure is put forward. The computer algorithm of forming network structure - Engineering proved to be correct. This method has changed the hand-drawn arrow-line initial network diagram, to a considerable extent depends on the experience and skills of the state, is conducive to the promotion and application of network planning technology. At the same time, it also explores the problem of logical isomorphism transformation in graph theory.
