Questions and Answers

1.

Which of these is not correct
- A.
  
  PERT is probabilistic in nature.
- B.
  
  CPM is deterministic in nature.
- C.
  
  CPM is event-oriented.
- D.
  
  CPM and PERT use similar terminology but were developed independently.
2.

_________ is not a rule of network construction.
- A.
  
  Only one arrow defines each activity.
- B.
  
  A network must have only an initial and only one terminal node.
- C.
  
  Final nodes and identical initial can identify two activities.
- D.
  
  None
3.

It is known that in a project, activity 4-6 has a duration of six days and a total float of three days. The E and L times at node 4 are 8 and 11, respectively, while, at node 6, both are equal to 17.Which of the following is not a true statement about 4-6?
- A.
  
  Its free float is three days.
- B.
  
  Its independent float is 0.
- C.
  
  It is a critical activity.
- D.
  
  The ES of this activity is 8.
4.

Pick the wrong relationship:
- A.
  
  Interfering float = Total float – Free float
- B.
  
  Total float =Free float + Independent float
- C.
  
  Total float ≥ Free float ≥ Independent float
- D.
  
  Free float = Total float – Head event slack
5.

Given, expected duration of the project = 47 days, variance = 9 days. What is the probability of not completing the project in 50 days? Z : 0.33 1.0Area : 0.1293 0.3413
- A.
  
  0.6293
- B.
  
  0.8413
- C.
  
  0.1587
- D.
  
  0.3707
6.

Given, expected duration of the project = 47 days, variance = 9 days. Expected Time for Project Completion: 50 days Z : 0.33 1.0Area : 0.1293 0.3413 What is the probability of completing the project within three days, more or less than the expected time?
- A.
  
  0.5000
- B.
  
  0.6826
- C.
  
  0.2586
- D.
  
  0.3174
7.

________ is not true about crashing?
- A.
  
  Always pay attention to the critical path and select between critical activities only.
- B.
  
  Crashing cost per day = (Crash cost – Normal cost) / (Normal time – Crash time).
- C.
  
  Always choose the activity with the least crashing cost.
- D.
  
  All are true
8.

CPM is:
- A.
  
  Critical Project Management
- B.
  
  Critical Path Management
- C.
  
  Critical Path Method
- D.
  
  Crash Project Method
9.

Mark the incorrect statement:
- A.
  
  A project can be called a set of activities that can be performed in a particular logical sequence.
- B.
  
  An activity cannot be represented by more than one arrow, but an arrow can represent one or more activities.
- C.
  
  An arrow which is representing an activity may have any kind of length and shape.
- D.
  
  All are correct
10.

Point out which of these is not required in Precedence relationships.
- A.
  
  All the predecessor(s) of an activity should be focused on.
- B.
  
  Should only focus on immediate predecessor(s).
- C.
  
  Should drop redundant predecessors.
- D.
  
  All of these
