Network Diagram Cp Most Optimistic

Then in order to provide connectivity to the network we join nodes 6l and 6 by a dummy activity.

Network diagram cp most optimistic. B perform a forward pass and backward pass through the network to determine the critical path the expected duration of the project and the slack time for each activity. C what is the probability that the project. By looking at the activity network diagram the team can easily see that the expected completion time as defined by the critical path is 50 days. Where t e is the expected time t o is the optimistic time t m is the most probable activity time and t p is the pessimistic time.

The line above shows the critical path. Instead we can retain them as different nodes. Construct a network diagram. An important point may be observed for the above diagram.

Network diagrams are useful in project management in many ways. Any delay of a task on the cp will delay the entire project zero slack on cp. Slack or float. Consider the following parts in the diagram 3 4 6 and 3 l5 6 we took nodes 6 and 6l as one and the same.

Network diagrams in project management are a visual representation of a project s schedule. The duration of an activity is calculated using the following formula. Optimistic time the team might want to know what the best case optimistic time in terms of time. Optimistic 4 most likely pessimistic 6.

Start studying network diagrams. Problem4 using the following project information choose the right network diagram optimistic time estimate weeks most likely time estimates weeks pessimistic time estimates weeks immediate predecessor s activity none 12 10 16 4 4 10 d e d e 10. A draw the pert network diagram for the project labeling all activities and times. The most optimistic.

Some of the benefits of using network diagrams include. Networkdiagrams paint a clear picture of how varying tasks fit in to a project and their specific interdependencies. A network diagram in project management is useful for planning and tracking the project from beginning to finish. Learn vocabulary terms and more with flashcards games and other study tools.

The most pessimistic. Most likely time and pessimistic time. The most likely. Cpm activity on node network diagram the second and more important difference is that traditional cpm applies a single duration and cost estimate for each activity whereas traditional pert applies a 3 point weighted average duration estimate optimistic most likely and pessimistic for each activity and does not consider cost.

It is the shortest time taken to complete the activity. 5 2 12 9 10 7 5 50 days that s the most likely time. Well known complements to network diagrams include the pert and gantt charts. Calculate the time earliest te and time latest tl for all the activities from the network diagram figure 8 24 the critical path is identified as1 4 4 6 6 7 with a project duration of 22 days.

It is not necessary to go into the theory behind the formula.
