中文摘要：

时间是决定R＆D项目成败的关键因素，因此业主通常都设置激励机制以确保项目按期完成，但长期以来对激励机制本身的优化并没有深入的研究。为此，本文首先对激励机制进行了界定，然后在传统资源约束型项目进度问题中引入了激励机制和柔性资源约束，从合同双方联合的角度构建了R＆D项目的激励机制优化模型。通过求解该模型，可获得与特定截至日期相对应的最优激励强度，该激励强度下的项目进度使合同双方同时获得最大收益。最后通过数值算例对研究结果做了说明。

英文摘要：

Time is the primary factor to the outcome of R＆D project, so the client usually setup incentive mechanism to insure the project being completed on schedule, but there is no expert study on the optimization of incentive mechanism itself. In this paper, we define the conception of incentive mechanism, introduce incentive mechanism and flexible, resource constraint to traditional resource constrained project scheduling problem to formulate incentive mechanism optimization model of R＆D project from both sides of the contract. By solving the model we can obtain the optimal incentive intensity to given dead date. Both sides of the contract can attain maximal income under the schedule with the optimal incentive intensity. Ultimately, the outcomes of the paper are illustrated by an instance.
