PROBLEM 1

Use the network diagram below and the additional information provided to answer the corresponding questions. [15 points] a) The crash cost per day per activity. [10 points]

A= (800-300) / (7-3) = 500/4 = 125

B = (350-250) / (3-1) = 100/2 = 50

C = (900-400) / (6-4) = 500/2 = 250

D = (500-200) / (3-2) = 300/1 = 300

E = (550-300) / (2-1) = 250/1 = 250

b) Which activities should be crashed to meet a project deadline of 10 days at minimum cost? What is the cost impact of crashing these activities? [3 points]

Path Duration: A-B-E = 12 days

B is cheapest ($50) 12 –10 = 2 2X 50 = 100

B for 2 days at $100

c) Find the new budget (or cost of the project). [2 points]

New budget: 300 + 250 + 400 + 200 + 300 + 350 = $1800 PROBLEM 2

Use the network diagram below and the additional information provided to answer the corresponding questions. [13 points] a) The crash cost per day per activity. [10 points]

A = (800-300) / (5-3) = 500/2 = 250

B = (350-250) / (3-1) = 100/2 = 50

C = (900-400) / (6-4) = 500/2 = 250

D = (500-200) / (5-2) = 300/3 = 100

b) Which activities should be crashed to meet a project deadline of 13 days at minimum cost? What is the cost impact of crashing these activities? [3 points]

Path Duration: B-C-D = 14 days

B is cheapest ($50) 14 -13 = 1

1 x 50 = 50

B for 1 day at $5
