Consider the network presented in the following table.Calculate a.All possible paths b.The critical path c.The slack available at any non-critical points d.The minimum project duration

A network consists of the following list.Times are given in weeks. a.Draw the network diagram. b.Calculate the expected duration and variance of each activity. c.Calculate the expected duration and variance of the critical path. d.Calculate the probability that the project will be completed in less than 28 weeks.

Which of the following statements regarding critical paths is true?

PERT,but not CPM,has the ability to consider the precedence relationships in a project.

Gantt charts give a timeline for each of a project's activities,but they do not adequately illustrate the interrelationships between the activities and the resources.

WBS stands for which of the following project management tools?

Given the critical path below,calculate the following: a.The crash cost per unit time savings for each activity. b.The maximum total crash time savings and cost. c.The maximum total time-savings with a $3000 budget.

Which of these statements regarding time-cost tradeoffs in CPM networks is true?

In PERT analysis,the identification of the critical path can be incorrect if a noncritical activity takes substantially more than its expected time.

Identify,in order,the six steps basic to both PERT and CPM.

A simple CPM network has three activities,D,E,and F.D is an immediate predecessor of E and of F.E is an immediate predecessor of F.The activity durations are D=4,E=3,F=8.

The control of projects involves close monitoring of which of the following?

A project being analyzed by PERT has 60 activities,13 of which are on the critical path.If the estimated time along the critical path is 214 days with a project variance of 100,what is the probability that the project will take 224 days or more to complete?

The network below represents a project being analyzed by the critical path method.Activity durations are indicated on the network. a.Identify the activities on the critical path. b.What is the duration of the critical path? c.Calculate the amount of slack time at activity H. d.If activity I were delayed by ten time units,what would be the impact on the project duration?

A project organization that becomes permanent is often referred to as a:

What was the name of the construction project to rebuild the Pentagon after the terrorist attacks on Sept.11,2001?

The network analysis method that allows activity times to vary is ________.

One responsibility of a project manager is to make sure that the project meets its quality goals.
