The earliest method of used for planning of project was
CPM
PERT
Milestone chart
barchart
The occurrence of the completion of an activity is called its
head event
tail event
dual role event
none of these
Crashing is
reduction in duration
reduction in resources
reduction in cost
reduction in size
In a project, the major quality control methods are
Testing & Sampling
Inspection & Testing
Inspection & sampling
Inspection, testing & sampling
Which of the following is not related to the cost slope
Crash cost
Normal cost
slack
Crash time
Direct cost includes cost of
Cost of materials, equipment and manpower
Cost of materials only
Cost of material, manpower
Cost of rent offices
Cost slope is given by
crash cost - normal cost / crash time - normal time
crash cost - normal cost / normal time - crash time
normal cost - crash cost / normal time - crash time
crash time - normal time / normal cost - crash cost
Cost slope gives the
increase in cost by increase in time
decrease in cost by increase in time
decrease in cost by decrease in time
increase in cost by decrease in time
Latest start and finish time in CPM is determined by
Forward pass
Backward pass
Upward pass
Downward pass
Total float is equal to
LST + EST
LST - EFT
LST - EST
LFT + EST
In PERT, the variance of an activity is determined by
(b-a)/6
(b−a)2/6
(b−a)/62
((b−a)/6)2
If the optimistic, most likely time and pessimistic time for an activity are 7, 8 and 10 respectively, the standard deviation is
0.5
0.25
0.20
0.35
Zero float for any activity means that the activity is
super-critical
sub-critical
Critical
Non critical
If an event has a TE of 10 days and a TL of 14 days, what is the Slack?
4 days
10 days
14 days
24 days
Which of the following is a key component of a construction site's emergency preparedness plan?
A list of aesthetic design elements
Accessible fire extinguishers and a clear evacuation plan
A budget for material procurement
A schedule for non-critical tasks
CPM, what happens if insufficient man-hours are allocated to a critical path activity?
The project's budget remains unaffected
The activity duration increases, delaying the entire project
Only non-critical activities are delay
The project's aesthetic design is compromised
Which one is not an example of direct cost
cost of materials
cost of equipment and machinery
cost of manpower
supervision charges
Which of the following is an example of indirect cost
overhead charges
Establishment charges
both a & b
only a
If the optimistic, most likely time and pessimistic time for an activity are 7,8 and 10 respectively, the variance is
0.5
0.125
0.225
0.25
A dummy activity
is artificially introduced
is represented by a dotted line
does not require time
all of these
Critical path
is always longest
is always shortest
maybe longest
may be shortest
CPM adopts
probabilistic approach
deterministic approach
stochastic approach
periodic approach
The settlement between the two parties can be done by
a third party or agency acceptable to both parties acting as a mediator and giving a settlement
disputes can be settled through litigation in a court of law
settlement of disputes by arbitration
all the above
If the variance of a dataset is 81, what is the standard deviation?
9
