One New Method to Solve Time-Cost Tradeoff Problem

Time-cost tradeoff problem is one core problem in project scheduling, and also is one difficult problem which project manager have to face. Methods of solving the problem mainly contain method of network flow and method of mending the minimal cost. There into, for the method of mending the minimal cost are intuitionistic, convenient and lesser computation, these advantages make the method being used widely in practice. But disadvantage of the method is that the result of each step is optimal but the terminal result maybe not optimal. In this paper, method of reducing duration directly is designed on the basis of the method of mending the minimal cost, and the result of solving time-cost tradeoff problem is more optimized.
