Exam 8: Scheduling

The series of connected activities (or intermediate events)between any two events in a network is called __________.

__________ law suggests that work expands to fill the allotted time.

Any time two or more paths of a network come together,the probability of both paths being on time is the product of the probabilities for the individual paths.This scenario is referred to as __________.

Describe the process for determining the critical path in a network.

Assume that task J has a most likely duration of 20 days,an optimistic duration of 13 days,and a pessimistic duration of 30 days.If the optimistic and pessimistic durations are 95 percent estimates,the standard deviation for task J is ________ days.

Explain the meaning of slack in a network.

The authors,when discussing networks,describe a(n)__________ as the result of completing one or more activities.It is an identifiable end state,which does not use any resources,occurring at a particular time.

Task F has duration of 10 days and an earliest start date of 20 days.Based on the given data,determine the early finish duration for task F.

In a network,if the delay of an activity will delay completion of the project,the activity is called a(n)__________.

In CPM(PDM),an activity can be conducted at a normal pace or an expedited pace,known as ________,at a greater cost.

The calculation of the standard deviation for the beta distribution is based on the assumption that __________.

__________ have a weakness of being difficult to follow when multiple paths exist,but __________ are more helpful in the hands-on task of managing the project.

Explain why it is important to evaluate non-critical paths that possess large variances and / or path times that are close to critical in duration.

The difference between the late start and early start for an activity is called its __________.

When using the beta distribution,the denominator of the formula for standard deviation should ________.

The arrangement of all activities (and,in some cases,events)in a project arrayed in their logical sequence and represented by arcs and nodes is called a __________.

Describe the benefits of forming a network of activity and event relationships that graphically portrays sequential relations between tasks in a project.

Project task E has the following estimates: (1)optimistic time - 10 days,(2)Pessimistic time - 20 days,and (3)Most likely time - 12 Days.The expected time using the beta statistical distribution is __________ days.

Explain the difference between Total Slack and Free Slack in a network.

The authors define __________ as the time an activity can be delayed without affecting the start time of any successor activity
