Abstract:
Time, cost and quality are considered as the main components in managing each project. Previous studies have mainly focused on the timecosttrade-off problems. Recently quality is considered as the most important factor in project’s success, which is influenced by timeacceleration. That is the less time is spent, the more success is gained. In time-cost-quality trade-off problems, each activity can be done invarious execution modes and determination of these execution modes is seen as to minimize the project time and cost and maximize itsquality. In this paper, three integer programming models are provided and one of the main objectives is optimized in each model byassigning the proper bound to other objectives. Following the non-dominated solutions obtained by solving models, and by means of hybridapproach of Fuzzy AHP strategy and VIKOR method regarded as multi-criteria decision making methods, the best possible alternative(from among non-dominated solutions) has been suggested
