Question

The Situation: An important client has just e-mailed you with an urgent request to rush her job, no matter what the cost. In turn, she agrees to pay all rush charges. You need to e-mail her back with a quote of the rush costs (cost to crash) and the number of days you can shave off her job. The data you need to develop the cost quote is provided below (these are the only activities that can be crashed): Determine which activities are on the critical path, its length, and the length of the other paths (there are a total offive paths). Be sure to indicate the critical path Start shortening the critical path (using the crash time table). Keep in mind that two pathways may become critical as you begin shortening the original longest path. What is the fewest number of days you can finish her job? What is the total dollar cost to crash he job lil

Explanation / Answer

Following are the paths

A -B -K= 12 + 14 + 9 =35 Days

C-D-G-M = 10 +17+15+3 = 45 Days

C-E-H-N = 10 + 18 + 8 +11 = 47 Days

C-E-H-P =10 + 18 +8+8 = 36 Days

F-I-J-P = 12+7+12+8 = 39 Days

Critical path =

C-E-H-N = 10 + 18 + 8 +11 = 47 Days

1) Fewest No of days =

Here activity C & E can be crashed .

C & E can be crashed by 2 & 1 days respectively.

So Fewest no of days = 47 - 2 -1

= 44 Days

2) Crash Cost =

Activity C + Activity E = 5000 + 18000

Crash Cost = $ 23000
