1. A dummy activity is artificially introduced in a network when necessary,
2. A dummy activity consumes some time.
3. A dummy activity is represented by a dotted arrow.
4. A dummy activity must necessarily be introduced in every network.
Which of the above statements are correct?

Detailed Solution for Test: CPM & PERT - 4 - Question 5

A dummy is introduced artificially and it is shown by a dotted arrow. It does not consume any time. It is not necessary to introduce a dummy always. Thus statements 1 and 3 are correct.

Codes:

Detailed Solution for Test: CPM & PERT - 4 - Question 6

A-4, B-1.C-2, D-3
Artifically introduced activity is dummy and it is shown by a dotted arrow.
Critical activity is represented by a single thick arrow.
Non-critical activity is represented by a single arrow. Dangler does not enter into any event.

Test: CPM & PERT - 4 - Question 7

With reference to the network shown in figure, which statement is incorrect?

Detailed Solution for Test: CPM & PERT - 4 - Question 7

Because dummy activity between events 3 and 7 imposes a restriction on the occurrence of event 7 unless event 3 also occurs.

Test: CPM & PERT - 4 - Question 8

Figure shows the network for a particular project which consists of four activities.

Normal duration time and crash time for each activity are given below:

The minimum time required for the completion of project is

Detailed Solution for Test: CPM & PERT - 4 - Question 8

This is the sum of crash times along the critical path.

Test: CPM & PERT - 4 - Question 9

In PERT analysis, event means
