What is a subcritical path?
An additional parallel path through the network with the total durations shorter than the critical path is called a sub-critical or non-critical path. Activities on sub-critical paths have no drag, as they are not extending the project’s duration.
What is critical route?
The critical path (or paths) is the longest path (in time) from Start to Finish; it indicates the minimum time necessary to complete the entire project.
What is supercritical activity?
Supercritical Activity: These Activities have negative float. It results when activity duration is more than timeavailable. It indicates abnormal situation requiring as to how to compress the activity. Subcritical path: The path with the next least floats than critical path is subcritical path.
What happens when the project is scheduled by CPM?
Critical Path Method (CPM) Scheduling is the most widely used scheduling technique in the Transportation market. This scheduling technique is used to plan and control a project and to calculate the minimum completion time for a project along with the possible start and finish times for the project activities.
How do you create a critical path in P6?
Press F9, and then click the Options button. Find the setting “Define Critical Activities as”. Choose Longest Path. Reschedule your Project.
What are near critical activities?
Near critical activities are those whose float (slack) is equal to one shift or less. These activities have a high potential of becoming critical. Activities with float between one and two shifts should be on a “watch list”, as they have the potential of becoming near critical.
What is sub critical activity?
Sub critical path means the second longest path in the network. It is shorter than the critical path but longer than all other paths in the network. All activities on the sub critical path are not critical. Some of the activities may be critical.
What is negative float for a task?
Negative float, also known as negative slack, is the amount of time beyond a project’s scheduled completion that a task within the project requires. Total float is the amount of time a task within a project can be delayed without endangering the project deadline.
What are the benefits of CPM?
There are several benefits associated with the CPM.
- Enhanced scheduling.
- Improved project management.
- More efficient distribution of human resources.
- Cost/budget control.
- Poor adaptation to change.
- Inability to determine the exact duration of tasks.
- A lot of time and effort required.
- Constant resource planning required.
