英文摘要：

The resource-constrained Max-npv project scheduling problem was studied. Firstly, the mathematical model of the problem was given, then a branch and bound algorithm for the resource-constrained Max-npv project scheduling problem was designed on the basis of rapid recursion search method. The feasibility of branch and bound algorithm was verified by using an example. The results show that the project profit drops with the increase of the cash discount rate, while increase with the prolongation of the project deadline.
