Activity R on a CPM network has predecessors M and N,and has successor S.R has duration 5.N's late finish is 18,while M's is 20.S's late start is 14.Which of the following is definitely true?

PERT calculations typically include the duration variance of each activity.What is the purpose of this calculation,i.e.what's the role of variances in PERT analysis?

The critical path can be determined by use of either the "forward pass" or the "backward pass."

An activity on a PERT network has these time estimates: optimistic = 1,most likely = 2,and pessimistic = 5.What is its expected activity time?

The critical path for the network activities shown below is ________ with duration ________.

If an activity whose normal duration is 13 days can be shortened to 10 days for an added cost of $1,500,what is the crash cost per period?

Two critical path activities are candidates for crashing on a CPM network.Activity details are in the table below.To cut one day from the project's duration,activity ________ should be crashed first,adding ________ to project cost.

Two critical path activities are candidates for crashing on a CPM network.Activity details are in the table below.To cut one day from the project's duration,activity ________ should be crashed first,adding ________ to project cost.

What is the basic difference between PERT and CPM?

If an activity whose normal duration is 15 days can be shortened to 10 days for an added cost of $2,000,what is the crash cost per period?

The critical path for the network activities shown below is ________ with duration ________.

Which of the following is NOT performed by Microsoft Project?

The difference between AON and AOA networks is that:

Which of the following statements concerning CPM activities is false?

Shortening the project's duration by deleting unnecessary activities is called "project crashing."

A project organization:

A project being analyzed by PERT has 38 activities,16 of which are on the critical path.If the estimated time along the critical path is 90 days with a project variance of 25,what is the probability that the project will be completed in 88 days or less?

A(n)________ divides a project into more and more detailed components.

The standard deviation of project duration is the average of the standard deviation of all activities on the critical path.

Which of the following statements regarding time-cost tradeoffs in CPM networks is false?
