摘要
为弥补关键链在软件项目进度管理应用中的缺陷,提出一种改进的基于三角模糊数的关键链管理方法。该方法使用三角模糊数表征活动工期,将工期中隶属度为1的时间作为活动的最可能工期,由此构建网络图,并考虑资源约束确定项目的关键链。为项目设置缓冲以吸收不确定因素对项目进度的影响,由此监控项目进度。通过案例演示该方法的使用过程,证实了该方法的有效性和实用性。
This paper proposes an improved critical chain management method based on triangular fuzzy number against the defect of application of critical chain in software project schedule management. It estimates activity durations with triangular fuzzy number, and takes the value whose degree of belonging to the activity durations is 1 as the highest possibility time of activity. Based on the highest possibility time of activity, activity-network is made. The project critical chain under resource constraints is built. Uncertainty in the project is absorbed through inserting buffers. Schedule control is performed by monitoring the penetration level in the buffers. Application process of the method is illustrated with a case, which proves the method is effective and practical.
