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

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.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 expected completion time of the laddered project?

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 takes more than 34 days?

An activity has an optimistic time estimate of 7 days,a most likely estimate of 12 days,and a pessimistic estimate of 20 days.What is the expected duration of the activity?

At a burst point in a backward pass,the largest succeeding late start becomes the late finish for that node.

Draw a network of any size that has at least one of each of the following features: merge activity,burst activity,hammock activity,ladder activity,critical path,serial activities,concurrent activities,and float.Mark these features on your network.

There's an old saying,"The job is not finished until the paperwork is done." From an activity network standpoint,this does not necessarily mean that the paperwork can't begin until the last non-paperwork activity is completed.It might be possible to work on some paperwork as early activities are completed.In order to depict this in an activity network:

The least amount of float is found:

A project's duration can be reduced by:

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

A project has the precedence requirements and activity durations shown in the table.After he draws the network,the project manager decides to represent a few activities by a hammock activity.Which is a legitimate hammock activity for this project?

A backward pass is performed when it is necessary to undo some work that has been performed in order to complete it properly.

What are hammock activities and when should they be used?

Hammock activities break a task into greater levels of detail so that each task is represented as two or more subtasks that each have their own duration and precedence requirements.

The late start time should be calculated using a forward pass through the network.

Construct a network using the information in the table and identify the critical path.

The longest route through the network is the ________.

Use the values in the table to calculate activity durations and variances for the project.Which path is critical? How closely should the other path be watched and why?

The amount of time an activity may be delayed from its early start without delaying the finish of the project is the:
