Exam 14: Materials and Resource Requirements Planning

If a project path has an expected duration of 10 days and a standard deviation of three days,what is the probability that the path will be completed in 13 days or less?

A simple sequential project (each task must be completed before the next one can begin)has the time estimates (in days)shown below: What is the likelihood the project will be completed in 10 days?

Given the tasks,estimated durations,and crash costs shown below,what is the total cost of the steps needed to provide the cheapest way to reduce the project length by three days?

Given the project data below,what is the expected length of path A,B,C?

A project manager has discovered that three tasks are on the critical path for a particular project.She has developed the time estimates (in days)shown in the table below.Complete the table and determine the probability that the project will be completed in 20 days or less.

Given the tasks,estimated durations,and crash costs shown below,which task would you crash first?

The four tasks below must be completed in order (a single path of tasks).Given the task information,what is the probability that the path of tasks will be completed in 20 days or less?

If a project path has an expected duration of 10 days and a standard deviation of three days,what is the probability that the path will be completed in 10 days or less?

Which of the following statements best describes "crash cost"?

Task X has a most likely duration of 10 days,a best-case duration of 8 days,and a worst-case duration of 15 days.What is the probability that it will be completed in 10 days or less?

A simple sequential project (each task must be completed before the next one can begin)has the time estimates (in days)shown below: What is the probability that the project will be completed within 8.5 days? (Choose the closest answer.)

Annie is planning a large surprise party for her sister Gwendolyn.She has developed the following plan,including estimates of the time (in hours)and cost necessary to perform each of the tasks required. If Annie saves $40 for every hour she can reduce from her plan,what is her total net benefit from crashing this project by six hours?

Given the project plan shown below,which task has the largest standard deviation (uncertainty)relative to its expected duration (standard deviation divided by expected duration)?

Given the tasks,estimated durations,and crash costs shown below,if the benefit to crash the project by each day is a maximum of $750,how many days would it be worthwhile to crash the project?

Annie is planning a large surprise party for her sister Gwendolyn.She has developed the following plan,including estimates of the time (in hours)and cost necessary to perform each of the tasks required. Annie will save $40 for every hour she can reduce from her plan.Annie has decided to crash her project and use the money she saves to purchase a larger gift for Gwendolyn.Which task should she crash first?

Given the project data below,what is the standard deviation of durations for path A,B,C?

Annie is planning a large surprise party for her sister Gwendolyn.She has developed the following plan,including estimates of the time (in hours)and cost necessary to perform each of the tasks required. Annie will save $40 for every hour she can reduce from her plan.If Annie crashes only task A to its minimum duration,how much will she save on the project?

Given the project plan shown below,for each task assume that the best-case duration is 80 percent of the most likely duration,and the worst-case duration is 150 percent of the most likely duration.What is the expected completion time for the critical path?

Which of the following statements is true regarding crash costs?

Given the tasks,estimated durations,and crash costs shown below,which task would you crash last in order to minimize the project length?
