Here is a list of activity times for a project as well as crashing costs for its activities. Determine which activities should be crashed and the total cost of crashing if the goal is to shorten the project by three weeks as cheaply as possible. There are three paths (top, middle and bottom). Each path contains three sequential activities which must be performed in the order they are listed (e. g., A before B, B before C). Note that Activity C is contained on both the top and middle paths. Path Activity Duration (weeks) First Crash Second Crash
Top A 5 $8 $10
B 6 7 9
C 3 14 15
Middle D 3 9 11
E 7 8 9
C 3 14 15
Bottom F 5 10 15
G 5 11 13
H 5 12 14

Suppose that a major city’s main thoroughfare, which is also an interstate highway, will be completely closed to traffic for two years, from january 2014 to december 2015, for reconstruction at a cost of $535 million. if the construction company were to keep the highway open for traffic during construction, the highway reconstruction project would take much longer and be more expensive. suppose that construction would take four years if the highway were kept open, at a total cost of $800 million. the state department of transportation had to make its decision in 2014, one year before the start of construction (so that the first payment was one year away). so the department of transportation had the following choices: (i) close the highway during construction, at an annual cost of $267.5 million per year for two years. (ii) keep the highway open during construction, at an annual cost of $200 million per year for four years. now suppose the interest rate is 80%. calculate the present value of the costs incurred under each plan.
