Exercise 2 Slide 12
Given the data and information that follow,
compute the total direct cost for each duration. If the indirect costs for each
project duration are $90 (15 time units), $70 (14), $50 (13), $40 (12), and $30
(11), compute the total project cost for each duration. What is the optimum
cost-time schedule for the project? What is this cost?

Answer:
We must compute this project for
understand the result. This is calculating of the project:
First i will making line project schedule for know line critical project. This is the line:
The critical line is act A, D, G
and I
Second i will compute the total direct cost for each duration
If we’re looking the result of
compute the project. So the total cost of project normal is 730 and candidate
of crashing is act G
And last, we will compute
indirect cost
