确定关键路径图(国外英文资料)Critical PathWhat is the critical pathIn project management, the critical path is refers to the network terminal sequence of elements, this series has the longest and determine the total duration of the entire project completed in the shortest time.The period of the critical path determines the duration of the project. The delay of the terminal elements on any critical path will directly affect the projects expected completion time (for example, no float time on the critical path).A project can have multiple, critical paths in parallel. Another parallel path, which is slightly less than the critical path, is called the secondary critical path.Initially, the critical path approach only considers the logical dependencies between the terminal elements. Resource constraints are added to the key chain method.The critical path method was invented by dupont.Key line characteristicsKey routes have the following features:1, the duration of the activity on the critical route determines the duration of the project, and the duration of all activities on the critical route adds up to the period of the project.Any activity on the critical route is a critical activity, and any delay in any activity can lead to a delay in the completion of the project.3, critical path from the starting point to the route of the project at the end of the longest route, so if you want to shorten the construction period of the project, must be on the critical path to find a way to, on the contrary, if the critical path takes longer, is the entire project completion date will be extended.The time required for a critical route is the shortest amount of time you can complete a project.Activities on key routes are the least of the time.Explore the critical pathThe vertex represents the event, the arc represents Activity, and the weight On the arc indicates that the Activity is called the Activity On Edge Network. AOE is used to estimate the completion time of the project. Such as:Figure 1 i
