Consider the following data for the project newt work that corresponds

to the warehouse expansion case problem.

Answer the following questions taking into consideration the

additional information provided.

a$.$ Develop the project newt work with activity scheduling $($i$.$e$.,$ a

table defining start time and finish time of each activity as well as

the slack and the critical path$).$ What is the expected project

completion time? What is its corresponding variance? $[8$ Marks$]$

b$.$ Determine the probability that the project can be completed in $40$

weeks and $46$ weeks? $[4$ Marks$]$

c$.$ Using the expected activity times as the normal time and the

following crashing activity information provided below. Determine the

activity crashing decisions $($activities$,$ # of crashing day per

activity, cost of crashing per crashed activity and the total cost$)$ in

order to reduce the expected project completion time by $5$ weeks $($i$.$e$.,$

$5$ weeks less than the expected project completion time obtained in

part al$)[8$ Marks$]$
