AE-JE Foundation CE: Construction Management: Quiz 2

Crashing of a network

1) Decreases the project completion time

2) Increases indirect cost

3) Increases number of working hours

4) May change the critical path of the network

of these, correct statement(s) is/are

A project network diagram is shown in the figure below

Normal time and crash time for each activity are given below

The minimum time required for the completion of the project is:

Consider following statements regarding various costs associated with a project:

(i) For any project, direct cost is increased when project duration is reduced.

(ii) Indirect cost increases with increase in project duration.

(iii) Crashing of a network decreases the direct cost.

(iv) Crashing of a network increases the indirect cost.

Correct statement (s) is/are:

For the following detail of network, which of the following activity should be crashed first?

In time-cost optimization, using CPM method for network analysis, crashing of activities along critical path is done starting with activity having

Cost slope is the ratio of

The normal duration and normal cost of activity are 27 days and Rs 55,000, respectively. The activity crash duration is 23 days, and the indirect cost is Rs 1000 per day. If the cost slope is 1700 rupees per days, then the total cost after crashing of the activity will be-
