A contractor is in the process of evaluating different scenarios for a project she wants to bid. She has already determined the WBS and the associated WPs and estimated the durations and the costs. She also determined the payment schedule she will propose. The data is tabulated below. The period is in weeks. The discount rate is given as 0.02% per week. Costs are incurred, and payments are made at the end of the activities. Besides the payments during the project execution, there will also be a payment of amount 300,000TL once the project is finished. Give a mathematical programming formulation using the summation signs with the bounds explicitly stated and solve the formulation using any IP solver.
