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 =$125 per day crashed b) 350-250/3-1= $50 per day crashed c) 900-400/6-4= $250 per day crashed d) 500-200/3-2= $300 per day crashed
e) 550-300/2-1= $250 per day crashed
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 ABE= normal length 12 (critical path)
Path CDE= normal length 11
B for 1 day @additional cost $50 and E for 1 day @additional cost of $250. Total $300.
c) Find the new budget (or cost of the project). [2 points] Normal Cost 300+250+400+200+300 = $1,450 Crashed Cost= $1,450 + $300 = $1,750
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 =$250 b) 350-250/3-1= $50 c) 900-400/6-4= $250 d) 500-200/5-2= $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 BCD= normal length 14 (critical path)
Path AD= normal length 10
B for 1 day @additional cost $50
PROBLEM 3 [8 points] Month | ACWP | BCWS | BCWP | 22 | $540 | $523 | $535 |
a) Calculate the CV (Cost Variance). [2 points] 535-540= -5
b) Is the CV over or under
