What is difference between CPM and PERT?

PERT is that technique of project management which is used to manage uncertain (i.e., time is not known) activities of any project. … CPM is that technique of project management which is used to manage only certain (i.e., time is known) activities of any project.

What is dummy activity?

A dummy activity is an activity added to a project schedule as a placeholder. … A dummy activity is intended to show a path of action in a project activity diagram and is employed when a logical relationship between two activities cannot be linked by showing the use of arrows linking one activity to another.

What is activity network in data structure?

activity network (activity graph) A graphical method for showing dependencies between tasks (activities) in a project. The network consists of nodes connected by arcs. … The longest path through the activity network gives the completion time for the project represented by the network.

Which is activity oriented network diagram?

An Activity Network Diagram is a diagram of project activities that shows the sequential relationships of activities using arrows and nodes. … An Activity Network Diagram is a diagram of project activities that shows the sequential relationships of activities using arrows and nodes.

What are used to represent activity in a network diagram?

The ADM, or activity network diagram, uses arrows to represent activities associated with the project. In ADM: The tail of the arrow represents the start of the activity and the head represents the finish. The length of the arrow typically denotes the duration of the activity.

What is activity on arrow network diagram?

The original form of network diagram that has effectively been superseded by the precedence diagram format. In an activity-on-arrow network, activities are represented by a line between two circles. A network diagram is created by connecting activities according to their dependence upon each other. …

What is activity on node?

Activity-on-node is a project management term that refers to a precedence diagramming method which uses boxes to denote schedule activities. These various boxes or “nodes” are connected from beginning to end with arrows to depict a logical progression of the dependencies between the schedule activities.

How do you draw activity on arrow network diagram?

Arrow Diagram ProcedureList all the necessary tasks in the project or process. … Determine the correct sequence of the tasks. … Diagram the network of tasks. … Between each two tasks, draw circles for “events.” An event marks the beginning or end of a task and can help visually separate tasks.More items…

What is the best characteristic of an activity network diagram?

An AND depicts the sequencing of the activities, the activities that must be completed before other activities can start (in series), the activities that can be performed at the same time (in parallel), and those activities critical to a project’s completion time.

What should a network diagram include?

A logical network diagram illustrates the flow of information through a network and shows how devices communicate with each other. It typically includes elements like subnets, network objects and devices, routing protocols and domains, voice gateways, traffic flow and network segments.

How do you explain a network diagram?

A network diagram is a graphical representation of the project and is composed of a series of connected arrows and boxes to describe the inter-relationship between the activities involved in the project. Boxes or nodes represent the description of activities and arrows show the relationship among the activities.

Which event is an oriented network diagram?

PERT uses event-oriented network diagrams in which arrows join successive events. For example, at a foundation construction project, the various events could be’foundation layout started,” foundation excavated,” sideboards fixed,” concreting completed’ etc.
