| 摘 要： | 离散时间-费用权衡问题(DTCTP)是项目进度文献中被研究最多的双目标优化问题,它通常以三种形式出现:1)P1:截止日期问题;2)P2:预算问题;3)P3:工期-费用曲线问题.然而,对问题研究都集中在P1上,P2被关注较少.首先建立了与一般项目网络对应的P2的数学模型,在分析模型特征基础上,设计求解模型的遗传算法.最后,通过3个数值实例,验证模型的正确性和算法的有效性.

| Abstract: | The discrete time-cost trade-offs problem(DTCTP) with bi_criteria optimization model is a most widely concerned in project scheduling literatures,which has been studied under three possible forms: 1)P1: the deadline problem.2)P2: the budget problem.3) P3: the time/cost profile problem.However,all the current researches focus on P1,by contrast,P2 is almost completely ignored.In this paper,the mathematic model of the P2 is firstly established,which is corresponding to the generic project networks.Based on the character of the model,a genetic algorithm is developed to solve the model.Finally,three numerical examples are used to demonstrate the effectiveness of the model and the algorithm. |
