1.AOV and DagThe activity network can be used to describe the arrangement of the sub-projects in the production planning, construction process, production process, process flow and other projects.generally a project can be divided into several sub-projects, which are called activities (activity). With these activities completed, the whole project was completed. For example, the representative of the computer Professional course, learning is a project,

1. Concepts In a directed graph that represents an engineering project, vertices are used to represent activity, and arcs are used to represent priority relationships between activities. In this way, directed graphs are used to represent active networks, activity on vertex network ). The most typical example is the priority relationship between the course and the course. If all vertices in an AOV network are in the topological sequence, the

directed acyclic graph: acyclic directed graph, abbreviated DAG (Directed acycline graph). A graph spanning tree is a forward tree, and a number of strongly connected components of a non-connected and forward graph generate a number of forward trees, which are formed to generate forests. Application in engineering planning and managementIn addition to the simplest case, almost all projects can be divided into several sub-projects called "Activities", and these sub-projects are usual

In a direction diagram of a representation project, an activity is represented by a vertex, and an arc is used to denote the priority relationship between activities, such that a graph is a vertex representing an active network, which we call the AOV network (activity on Vextex Network). The arcs in the AOV network indicate that there is some kind of restriction relationship between the activities, the

Topological ordering as an application of diagrams, understanding the topological ordering must first understand the AoV diagram.The AoV network represents a vertex in a forward graph, with arcs representing the precedence relationship between vertices. As shown in the AOV network, if there is a path from the vertex VI to the vertex VJ, the vertex VI is the precu

I will introduce the basic storage methods, DFS and BFS, undirected graphs, Minimum Spanning Tree, shortest path, and active network (AOV and AOE) in detail.C ++Graph application. We have already introduced the first five aspects in the previous article. Today we will introduce the last one --Activity Network(AOV,AOE). Activity Network (AOV, AOE) This part is rel
