1. The AOE network is closely related to the AOV network. If a directed edge is used in a DAG to represent various activities of a project, the directed edge is used to indicate the activity duration, and the vertex is used to represent the event, this directed graph is called an Activity On Edge (AOE network;

As we said earlier, topology sequencing is primarily about solving the problem of whether a project can be sequenced, but sometimes we need to solve the problem of the shortest time required to complete the project. If we want to get the shortest time for a flowchart, we have to analyze their topological relationships and find the most critical process, which is the shortest time.
On the basis of the AOV network, we introduce a new concept. In a weighted direction diagram of a representation pr

We briefly introduce some concepts of AOE network and key path, and then analyze the main function of solving the critical path program. The existing AOE net Figure 7-9-4 shows that we use the adjacency table storage structure, attention and topology ordering when the adjacent table structure is different, where the ARC table node added weight field, used to store the arc of the weight value.

Prerequisites
1. Because the entire project has only one start point and one end point, under normal circumstances (no ring), there is only one inbound point and one outbound point of 0 in the network.
2. Unlike the AOV network, some activities in the AOE network can be performed in parallel. Therefore, the shortest time for project completion is the length of the longest path from the start point to the completion point. The path with the longest len
