A linear programming approach to maximize savings by stretching noncritical activities.

In this research, some concepts of linear programming and critical path method are reviewed to describe recent modeling structures that have been of great value in analyzing project time-cost trade-offs problems. This paper mainly provides a framework for the approach of stretching noncritical act...
