Trading off Time–Cost–Quality in Construction Project Scheduling Problems with Fuzzy SWARA–TOPSIS Approach

The increasing number of construction projects together with the limited resources organizations led to tough competition for achieving project goals. Time, cost, and quality have been known as iron triangle. Project managers attempt allocate appropriate make best decisions accomplishing shortest durations, lowest costs, highest quality. No study has examined time–cost–quality trade-off problem decision-making approaches. In this study, fuzzy multi-criteria (MCDM) methods are exploited choose mode performing each activity. For purpose, SWARA method is applied determine importance weights time, addition, TOPSIS (Technique Order Preference by Similarity Ideal Solution) technique used rank select activity execution modes. proposed model implemented on two medium- large-size evaluate its efficiency. Several modes duration, considered Finally, sensitivity analysis conducted taking three different conditions into account: duration modes, cost solution compared obtained from SWARA–TOPSIS method. schedule developed according results in show significant improvements overall objectives so that can be completed fewer durations costs along higher Because closer cost. also most likely high-quality level. application approach create new opportunities research knowledge development field scheduling.
