Question: consider the following network for a small project all times...

Question details

Consider the following network for a small project. All times are in weeks; and the network proceeds from node 1 to node 6.

Activity    Initial Node Final Node Estimated Duration
A 1 2 4
B 2 3 6
C 2 4 2
D 3 4 5
E 3 5 1
F 4 5 1
G 4 6 10
H 5 6 8
  1. Draw a network diagram representing the project below. Put the node numbers in circles and draw arrows from node to node, labeling each arrow with the activity letter and estimated duration.
  2. Determine how many paths there are in this network diagram, and write the paths and their lengths below. For example, a path might be written as A-B-E-G with a length of 12 weeks.
  3. Given the above information, what is the minimum amount of time this project will take to complete?  
  4. Which activities or tasks are on the critical path?
  5. Assume activity A has an optimistic duration estimate of 2 weeks, a most likely estimate of 4 weeks, and a pessimistic estimate of 12 weeks.What would be the PERT estimate for this task? Show your work/calculations to get full credit.
