Consider the following project activities:

a$.(*)$ Draw the project network diagram.

b$.(*)$ Identify all the paths through the network and their

lengths.

c$.(*)$ Identify all the critical activities and path$($s$).$ How

long will the entire project take?

d$.(**)$ After you complete part b and before you perform

the forward and backward passes, you should already

be able to tell that activities A and $N$ are on the critical

path$($s$).$ Why?

e$.(**)$ After constructing the project network diagram,

management comes up with the following informa$-$

tion regarding how many days certain activities can be

crashed and at what cost:

Suppose that every day the project goes on costs the com$-$

pany $$3,500.$ How many days should management crash

the project? What activities should it crash? What is the

new project length? Consider the following project activities:Im$$tin
