The following precedence diagram shows all the activities involved in the construction of one floor of a high-rise building. The duration of each activity is also given (in days).  There are 18 typical floors to be constructed for this high-rise building.

When Should Activity C Start?

For the given overlapping network diagram:

(1) Describe the relationship between all activities.

(2) Calculate the Early Start Date and Early Finish Date of each activity.

(3) Determine the project duration.

What is finish time of the project?

See below for a project's precedence diagram and each activity's duration given in the table. 

(1) If the project manager for the following project wants to be at least 80% sure about the scheduled completion time, how many weeks the project should be scheduled?

(2) What is the possibility that the project will complete in less than 32 weeks?

What is earliest finish date of activity F?

An overlapping network diagram is given below, what is the Early Start Date of Activity C? 

30 similar houses are to be built in a housing project. For each house, 10 trade activities need to be carried out, and their relationships are given in the following network diagram. The duration of each trade activity for one house is listed in the table. 

Assume all the trade activities need to be carried out continuously and the total project needs to be finished in the shortest possible time.

(1) Calculate the total duration, starting week and finishing week for each trade using the LOB method.

(2) Determine the total project duration.

What is latest start date (LSD) of activity E?

Explain what are time schedule, resource schedule and target schedule? (in about 120 words)

For the given overlapping network diagram:

(1) Describe the relationship between all activities. (For example, AC is Finish to Finish).

(2) Calculate the Early Start Date and Early Finish Date of each activity.

(3) Determine the project duration.
