Presenting a goal programming model in the time-cost-quality trade-off

Time, cost and quality are important objectives of each project, which project managers are always looking for completion of them in the shortest possible time, with the lowest cost and highest quality to be succeeded in the projects. One of the main challenges in this case is choosing the right approach to achieve these objectives. In this regard, the most commonly used approach is the use of balancing method. Indeed, using this method can be the most optimal mode of project implementation activities that the lowest and highest quality at the lowest cost, time has obtained. In this paper, a goal programming model is developed to find suitable solutions to manage the cost, time and quality of the project. In order to examine the developed model, a case study has been accomplished in the project implemented by Arak Machine Sazi Company. Computational results show the applicability of the model and the efficiency of proposed method.
