摘 要：正The time-cost trade-off problem studies how to modify project activities to achieve the trade-off between the completion time and the total project *** real world,the trade-off between the total project cost and the completion time,and the uncertainty of the external environment are both considerable for *** this paper,a new fuzzy random time-cost trade-off model is proposed,in which the philosophy of chance-constrained programming is introduced as decision-making *** approach by integrating fuzzy random simulation and genetic algorithm is produced to search the quasi-optimal *** the whole,this paper is to illustrate the process of achieving the optimal balance of the completion time and the project total cost in mixed uncertain environment with randomness and fuzziness.
