摘要：Delay in project schedule is a common issue in construction industry. Considerable percentage of projects are falling behind the schedule causing damage to almost every involved party. In this thesis, schedule crashing for compensating delay and reducing the duration of project have been studied. A framework is developed for the process of crashing and quantitative risk evaluation. Framework consist of two parts, in first part linear programming approach is used for the formulation of crashing problem and it is solved using excel solver. In second part probabilistic Quantitative risk evaluation of schedule after crashing is done with the aid of @RISK7.5. An example of crashing is solved using the developed framework which shows that the optimum crashed duration of an undertaken project is 51 days at which the total project cost is minimum and it is also seen that the project duration can further reduce to 49 days but at this duration total project cost is not minimum. After 49 days crashing is not possible. Then quantitative risk evaluation is done and it is found that initial probability of project completion is more than that after crashing which shows that after crashing the project we get desired completion date but the risk of completing project on time is increased..
