Tommy Pickles, CEO, is contemplating producing smaller ovens for use in high school and college kitchens. The activities necessary to build an experimental model and related data are given in the following table: NORMAL CRASH NOR CRASH COST (S) COST (S) IMMEDIATE PREDECESSOR(S) TIME ACTIVITY (WEEKS (WEEKS 4 1,500 2,300 400 1,400 900 3,600 1,600 1,800 2,500 400 1,700 1,200 5,100 2,200 4 D, E What is the project completion date? a) b) Crash this project to 10 weeks at the least cost. c) Crash this project to 8 weeks (which is the maximum it can be crashed) at the least cost.Explanation / Answer
a.
Most lenghty activity in the table is A, D & G which takes 4, 8 and 2 weeks respectively to completely. Thus total of 14 weeks it will take for the project to be completed.
b.
Though C and F activities are parth of the project, it does not delay anyone thus we need not crash it. Only we need to shorten A, D & G to 4 Weeks and B, E & G to 2 weeks. The most cost effective way is to bring down D & E by 4 and 2 weeks respectively wherein the cost of crashtime is the least per week compared to other activities in line.
So Crash D & E by 4 and 2 weeks respectively.
c.
Though C and F activities are parth of the project, it does not delay anyone thus we need not crash it. Only we need to shorten A, D & G to 6 Weeks and B, E & G to 4 weeks.If we crash D fully to the crash time it will take 3 weeks and reduce A to 3 weeks while leaving G as it is. for Path A, D and G it will take 8 weeks time.
SImilarly for B, E and G we need to crash B and E which are cost effective for per week crash time. then B will take 2 weeks, E will take 4 weeks while leaving G as it is will complete set of activities in 8 weeks of time.
Thus finally Crashing A, B, D and E to Crashtime will make the project to complet in 8 weeks.
