KOE Automation developed a proposal for introducing a new computerized office system that will improve word processing and interoffice communications for the Rector Building. Contained in the proposal is a list of activities that must be accomplished to complete the new office system project. Use the following relevant information about the activities.

$\backslash$table$[[$Activity$,$Description,$\backslash$table$[[$Immediate$],[$Predecessor$]],$Time $($weeks$),$Cost $($e $1000$s$)],[$Normal$,$Crash,Normal,Crast$],[,,10,8,30,70],[,$Plan needs Order equipment,A$,8,6,120,150],[$B$,$Order equipment,B$,10,7,100,160],[$C$,$Install equipment,A$,7,6,40,50],[$E$,$Conduct training course,D$,10,7,120,150],[$F$,$Test system,C$.$ E$,3,3,60,-]]$

a$.$ Develop a project network.

b$.$ Develop an activity schedule.

c$.$ What are the critical activities, and what is the expected project completion time?

d$.$ Assume that the company wants to complete the project in six months or $26$ weeks. What crashing decisions do you recommend to meet the desired completion time at the least possible cost? Work through the network and attempt to make the crashing decisions by inspection.

e$.$ Develop an activity schedule for the crashed project.

f$.$ What added project cost is required to meet the six$-$month completion time?

only direct cost

g$.$

The indirect costs for each duration are given:

$\backslash$table$[[$Project Duration,Indirect cost $(1000$s$)],[31,500],[30,450],[29,400],[28,350],[27,300],[26,250],[25,210],[24,190]]$

Rector Building offers you $10,000$ for every week you shorten the project from the original network.

a$)$ Would you take it$?$

b$)$ What is the optimum cost$-$time schedule? Compute the direct, indirect and total costs for each duration as well as identify the crashed activity.

c$)$ How much do you manage to get from the offer?ok
