Problem 1 Consider the project information below. Assume that the overhead cost of the project is $75 per unit time. (35 points) a) What is the optimal project duration that will minimize the sum of direct and indirect costs and what is the total cost of this project? (15 points) b) The following payment schedule is associated with some events (nodes). The interest rate is 15%(r=0.15). Find the optimal payment schedule for this project.
