Topic Description Narration a non-circular, forward graph is called a non-circular graph ( directed acyclic Graph dag figure. AOE (activity on edge) network: As the name implies, use the edge to represent the active network, of course, it is also a DAG. Unlike AOV ,
critical path: The path length from the source point to the sink point is the longest route called the critical path. A (1..N) in the figure represents the time spent between two activities. : The key
case of a shell completion event, in order not to affect the duration: Shell completion Activities at the earliest, it started at a point, and it must start at two o ' night. The maximum power value of 3 means that all activities must be completed after three hours, while the shell will take only 2 hours to complete. Therefore, the middle of the idle time has one hours, in order not to affect the entire du
/*Name: The critical path for topological sequencing (depth-first search)Copyright:Author: A clever clumsyDate:17-11-14 21:02Description: The key path of topological sequencingIn a weighted graph, the event is represented by a vertex, an activity is represented by a forward edge, and the weight on the edge represents the cost of the activity, such as the duration
Related concepts:(1)AOE (activity on Edges) network if there is a forward edge in the non-forward loop of the weighted direction graph to indicate the activities in a project , the weight on the edge represents the duration of the activity (Duration), When a vertex is used to represent an event , such a graph is called a network with an edge representing the activity, or AOE (activity on Edges). The AOE Network is a weighted, forward-free, circular
use AOE net to estimate the time of project completion?Two principles:?? Only events that are represented by a vertex can start with activities from that vertex?? Only events that enter a vertex end, and the event that the vertex represents can occur?Calculate critical pathsFirst, in the AOE network, the path from the beginning to the end with the maximum
