Consider the following data for a project. Draw the project network. Compute the total direct cost for each project duration. If the indirect costs for each duration are $1,200 for 16 days, $1,130 for 15 days, $1,000 for 14 days, $900 for 13 days, $860 for 12 days, $820 for 11 days and $790 for 10 days, compute the total project cost for each duration. 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?
