Q.1
Explain project management (PERT) & Project scheduling of PERT.
Answer
: Some key points about PERT are as
follows:
1. PERT was developed in connection
with an R&D work. Therefore, it had to cope with the uncertainties that are
associated with R&D activities. In PERT, the total project duration is
regarded as a random variable. Therefore, associated probabilities are
calculated so as to characterise it.
Q.2
Write a short note on Monte-Carlo simulation? What are the Limitations of using
Simulation?
Answer : Simulation is also called experimentation in
the management laboratory. While dealing with business problems, simulation is
often referred to as ‘Monte Carlo Analysis’. Two American mathematicians, Von
Neumann and Ulan, in the late 1940s found a problem in the field of nuclear
physics too complex for analytical solution and too dangerous for

Q.5
Define PERT & CPM. Write down the basic difference between PERT and CPM.
Answer : A PERT chart is a project
management tool used to schedule, organize, and coordinate tasks within a
project. PERT stands for Program Evaluation Review Technique, a methodology
developed by the U.S. Navy in the 1950s to manage the Polaris submarine missile
program. A similar methodology, the Critical Path Method (CPM) was developed
for project management in the private sector at about the same time.
