摘　　要：研究目的:目前的工程项目面临着环境不确定性和资源限制等因素的制约,使传统的网络计划技术已无法满足日趋复杂的建设项目对进度计划的可行性和稳健性的要求,因此,有必要提出应用模糊关键链编制项目进度计划的新方法。研究结论:在考虑实际项目的资源约束和不确定性问题的基础上,提出应用模糊关键链进行项目进度调度的方法,即采用改进的遗传算法求出在期望工期下的关键链和各工作的最优开始时间,并给出确定项目缓冲区和输入缓冲区大小的算法。该方法融合了关键链方法的优势,着眼于整体项目,可以编制出可行而稳健的项目进度计划,尤其适用于实际过程中资源约束和不确定项目的进度编制,可作为项目管理人员编制进度计划的一个有效工具。Research purposes： Nowadays the construction projects face the limitations of environmental uncertainty and constrained resource, so the method for traditional network planning can not satisfy the demands of increasingly complex construction projects for the feasibility and steadiness. Thus, it is necessary to use fuzzy critical chain for making the construction project schedule. Research conclusions：Based on the consideration of the constraints and uncertainties of resources to the construction projects, the new method is offered for making construction project schedule with critical chain method, namely using improved genetic algorithm to identify critical chain, determine the optimal start time of each activity under a desirable schedule and present the algorithm for determining the sizes of the project buffer area and feeding buffer area. The feasible and stable project schedule can be made with this method, because this method integrates the advantages of critical chain method and focuses on the whole project. This method is especially suitable for making the project schedule under the constraints and uncertainty of resources and can be as an effective tool for making the project schedule.
