Chapter 6, Problem 2E
a. AOA network diagram:
Explanation of Solution
Draw an Activity on Arrow (AOA) network diagram representing the project given in Table 6.2 of the book. To accomplish the network diagram, follow the following steps:-
1. Put the node numbers 1 to 9 in circles.
2. Find all of the activities that start at node 1. Draw arrows between node 1 and those finish nodes. Put the activity letter and duration estimate on the associated arrow. In this case, Draw an edge from node 1 to 2 and label it as A=2. Label A=2 means activity A has a duration of 2 days.
3. Continue drawing the project network diagram until all activities are included on the diagrams that have dependencies.
4. Label each arrow with the activity letter and estimated time. The below network diagram has 11 arrows corresponding to 11 rows in the table.
- Draw second edge from node 2 to 3 and label it as B=2...
b. All paths on the network diagram:
Explanation of Solution
To identify all the paths on the network diagram, just follow the arrows to identify distinct routes from node 1 to node 9.
To find out length of each path, just add the duration for all activities on that path.
| Path No | Route | Length / Total Duration |
c. Critical path for this project
Explanation of Solution
The longest path in the network diagram is the critical path...
d. Shortest possible time needed to complete this project:
Explanation of Solution
The critical path represents the shortest time requir...

Your task for this assignment is to create a network diagram for two projects. The activity, immediate predecessor and duration are given. You are to layout-long-hand or using some software-a network diagram for each project. For each diagram conduct a forward and backward pass, calculate the slack, and identify the critical path. When noting your early start, early finish, late start, late finish and slack, please use the format provided."
Project 1
in the textbook. All duration estimates or
hes are in days, and the network proceeds from Node 1 to
Node 9
Draw an AOA network diagram representing the project. Put the
node numbers in circles and draw arrows from node to node,

labeling each arrow with the activity letter and estimated time.
Draw an PDM network diagram representing the project. Determine
the early start,early finish,late start and late finish date for every
activity and mark them at the four corners of each activity.

3.
Identify all of the paths on the network diagram and note how long
they are, using Figure 6-8 as a guide for how to represent each
path.
