UNIT VII

Part 1

Develop an in-depth schedule for the project you selected and used to develop the statement of work and work breakdown structure in Unit III. Please refer to the Integrated Project in Chapter 10 on page 363 (Project Scheduling) of the textbook for more information. Be sure to include the following components:

· an activity precedence diagram,

· an activity duration table, and

· a network diagram and Gantt charts.

·

Please complete Case Study 10.1: Project Scheduling at Blanque Check Construction on page 360 of the textbook and answer the three questions at the end.

Q2(ANS)

According to my research level and literature review the expert opinion and past history both are the best to solve problem for calculating the critical path ,which may also tell us the duration or project delay to handle or run our construction company.

Q3(ANS)

These both have some strengthens and weaknesses and both give the results probably same , but according to literature AOA is the beneficial for modeling it will be helpful and in the business field it will be important AON will be less widely used , in case of large and complex projects it is easier to employ the path process used in the AOA . according to AOA we achieve the every milestone and particularly used the dummy projects or activities the concept of dummy project is not simple and easy it require more training and practice . AON Convention ,AOA network used both nodes and arrow to label the project.

Part 3

Develop a network activity chart and identify the critical path for a project based on the information provided in the Gantt chart below. Draw the activity network as a Gantt chart. What is the expected duration of the project?

An activity precedence diagram:

The total paths can be calculated there the first diagram can be defined the overall paths which are given below

ABEFIJ=5+10+5+10+12+6=48

ABEFGHJ=5+10+5+10+14+3+6=53

ACEFIJ=5+8+5+10+12+6=46

ACEFGHJ=5+10+5+10+14+3+6=51

ADFIJ=5+1+10+12+6=34

ADFGHJ=5+1+10+14+3+6=39

Critical path:

The 2nd path can be constructed for the critical path which have the longest path duration

ABEFGHJ=5+10+5+10+14+3+6=53

Its known as a critical path for the given activity.

Part 4

Using the information provided in the Gantt chart below, construct the project activity network using the activity-on-node (AON) methodology, and label each node. Identify the critical path and other paths through the network.

SOLUTION:

1

Part 1:

6

The critical path can be choose which have the minimum slack and then find the duration or delay of critical path first of all we find the critical path of given activity the critical path have minimum slack but delay should be maximum, which are given below

ACDFH=3+7+3+4+5=22days/min

With the critical point of slack, the flexibility of the project is limited
