The network for an artificial intelligence software development project, along with the normal durations, minimum durations, direct costs, and reduction costs for each project activity, are given below (Figure 1). During the planning stage, the project manager estimates that the project duration would be 16 weeks. However, he would like to reduce the time to complete this project, to ensure that he is first to market. Answer the following questions: 1. Knowing that the overhead costs for each duration are $460 (for 16 weeks), $430 (for 15 weeks), $350 (for 14 weeks), $270 (for 13 weeks), $180 (for 12 weeks), $160 (for 11 weeks), and $120 (for 10 weeks), calculate the total cost for each duration.

2. Plot the total direct costs, indirect costs and project costs for each duration on a cost-duration diagram. What is the optimal cost-duration combination?(its french!)
