文摘This paper discusses the tree a core data structure of one kind of project progress management software,and the implementation and optimization of algorithms of searching and traversal. In the algorithm D&C method is used throughout the process. We also try to change method of backtracking some key nodes so as to increas the speed of traveling throughout the tree.
文摘为解决工程施工进度管控关键链技术应用中存在的缓冲区计算方法粗略,缓冲区监控方法脱离实际施工的问题,通过引入风险控制系数、资源影响系数、工序复杂系数、工序位置系数以及环境系数五个指标,运用层次分析法和CRITIC(Criteria Importance Through Intercriteria Correlation)客观赋权法构建缓冲区优化模型;将缓冲区消耗率和项目工作链完成进度百分比相关联,建立了缓冲区动态监控机制。运用缓冲区优化模型和动态监控机制改进关键链技术,将改进关键链技术应用于泵站工程施工进度管理。结果表明:该方法所得到的缓冲区尺寸较为合理,可以实现缩短计划工期和实现缓冲区动态监控,为水利工程施工进度管控提供借鉴。
