    Master Thesis
    A time-cost tradeoff analysis of a construction project in Baghdad city using project management techniques
    (Çankaya Üniversitesi, 2018) Abd, İbraheem Mohammed
    One of the most remarkable challenges facing the project management at present, that is ensuring the completion of the project in spite of being subject to specific constraints, including time limitations and other financial resources allocated to the project, so this requires accurate calculation of the time and cost. The project of building the Muslim bin Aqeel school in AL-Taji area is one of the huge projects that the ministry of Sunni Endowment seeks to accomplish in Baghdad province. This project was chosen as a project in which the work is delayed, which led to a delay in its completion at the scheduled time. On this basis, the project was studied again according to scientific and mathematical methods to create a model that finds a suitable tradeoff between time and cost to accelerate the accomplishment process, by using one of the methods of scheduling and management of the project which is the critical path method CPM, To plan the project, determine the relationships of activities, calculate the slack and critical times to determine the longest duration and the cost required to complete the project. The problem of time-cost tradeoff TCTP and the discrete time-cost tradeoff problem DTCTP, are modeled, using the mixed integer programming model, then by converting the model into an optimization programming language OPL model. Here, IBM ILOG CPLEX Optimization Studio is used to find the optimal to the problem. The results showed that it is possible to reduce the delivery time by 19.29% less than the expected time by increasing the total cost by 5.77%.
