Question:
Assume the network and data that follow. Compute the total direct cost for each project duration. If the indirect costs for each project duration are $400 (19 time units), $350 (18), $300 (17), $25 (16) compute the total project cost for each duratin. Plot the total direct, indirect and project costs for each of these durations on a cost-time graph. What is the optimum cost-time schedule for the project and the cost?
