Exam 9: Project Scheduling: Networks, duration Estimation, and Critical Path

What is the early start time for Activity G given the activity times and precedence requirements shown in the table?

A gentleman farmer maniacally works on academic projects to raise funds for his true passion,farming.He has identified seven tasks and developed three time estimates (all in days)of the next big project on the farm,replacing the fence at the comedy pasture.Tasks,precedence requirements,and time estimates are shown in the table.What is the probability that the project is completed in 31 days?

An activity with two or more immediate predecessors is a(n):

In assigning a value for the most pessimistic (b)duration,the project manager should estimate the duration of the activity to have a 99% likelihood that it will take b or less amount of time.

Use the information in the table to determine the late finish time for Activity B.

A project has the precedence requirements and activity durations shown in the table.After he draws the network,the project manager decides that activities E and F can be represented by a hammock activity.What are the duration and the early start time associated with this hammock activity?

What is the slack time for activity E?

Activity Z has estimates a = 5,b = 10,m = 7;activity X has estimates a = 4,b = 11,m = 6;and activity Y has estimates a = 3,b = 12,m = 8.Which of the following statements is best?

What is the early start time for Activity D given the activity times and precedence requirements shown in the table?

The amount of time that an activity may be delayed from its early start without delaying the entire project is ________.

Preceding activities are those that must occur before others can be done.

Project Test Bank is composed of activities we will refer to as A,B,C,and D for convenience (and lack of creativity).Durations and precedence requirements are shown in the table.Each of these activities can be conveniently laddered into two sub-activities of equal duration,so activity C in the original project becomes two activities,C1 and C2,each of which lasts 7 days.The first half of each activity serves as the predecessor to its second half and the first half of the original following activity.What is the difference in the late start time for activity C in the original project and activity C1 in the laddered project?

Ray's shipment of materials hit every red light and traffic jam on the way to the site.Upon arrival,half of the material was judged defective,necessitating a trip back to the supplier,and then the same arduous journey back to the site once the new materials were loaded.Traffic was a little better on the second round but the flat tire and subsequent repair caused as much if not more delay than the first trip.In the final analysis:

The term ordered activity means:

Use the network diagram and activity lengths in the nodes to determine the early start time for activity D.

Based on the activity network pictured,what is the best statement?

________ activities have two or more immediate predecessors.

Activities C,D,and E in the project represented by the network are to be hammocked.What are the early start and late finish times of the hammock activity?

Use the information in the table to determine the early start time for Activity B.

Activity float is the difference between the late finish and early finish for the activity in question.
