CHAPTER 9: PROJECT SCHEDULING: PERT/CPM
QUESTIONS AND VERIFIED DETAILED SOLUTIONS
( MULTIPLE CHOICES) |100% CORRECT!!
(T/F) Critical activities are those that can be delayed without delaying
the entire project Correct Answers FALSE
(T/F) PERT and CPM are applicable only where there is no dependence
among activities Correct Answers FALSE
(T/F) A path through a project network must reach every node Correct
Answers FALSE
(T/F) A critical activity can be part of a noncritical path Correct
Answers TRUE
(T/F) When activity times are uncertain, an activity's most likely time is
the same as its expected time Correct Answers FALSE
(T/F) The earliest finish time for the final activity is the project duration
Correct Answers TRUE
(T/F) The length of time an activity can be delayed without affecting the
project completion time is the slack Correct Answers TRUE
, (T/F) When activity times are uncertain, total project time is normally
distributed with mean equal to the sum of the means of all of the critical
activities Correct Answers TRUE
(T/F) Crashing refers to an unanticipated delay in a critical path activity
that causes the total time to exceed its limit Correct Answers FALSE
(T/F) Constraints in the LP models for crashing decisions are required to
compare the activity's earliest finish time with the earliest finish time of
each predecessor Correct Answers TRUE
(T/F) The project manager should monitor the progress of any activity
with a large time variance even if the expected time does not identify the
activity as a critical activity Correct Answers TRUE
(T/F) The variance in the project completion time is the sum of the
variances of all activities in the project Correct Answers FALSE
(T/F) The latest finish time for an activity is the largest of the latest start
times for all activities that immediately follow the activity Correct
Answers FALSE
(T/F) The earliest start time for an activity is equal to the smallest of the
earliest finish times for all its immediate predecessors Correct Answers
FALSE
