工程施工关键线路 工程施工关键线路提要：关键线路并不是一成不变的，在一定条件下关键线路可以转化成非关键线路，当计划管理人员采取一定的技术组织措施 源自物业论文 工程施工关键线路 在单代号网络图和双代号网络图中，线路（指从网络图的起点节点出发，沿着箭线的方向到达终点节点，中间由一系列节点和箭线所组成的通道）均分为：关键线路和非关键线路两种。 其中关键线路指网络图中工期最长的线路，即主要矛盾线。在网络图中，关键线路具有以下性质：关键线路的线路时间（指完成网络图某条线路的全部工作所必须的总持续时间，它代表该条线路的计划工期）代表整个网络图的计划总工期；位于关键线路上的工作均为关键工作；关键工作没有时间储备，它完成的快慢直接影响整个网络图计划工期的实现；在网络图中关键线路不止一条，有时可能同时存在若干条； 关键线路并不是一成不变的，在一定条件下关键线路可以转化成非关键线路，当计划管理人员采取一定的技术组织措施，缩短某些关键工作的持续时间时，就有可能使关键线路发生转移，由原来的关键线路变成非关键线路。关键线路一般用粗实箭线或双箭线表示。 源自物业论文 Measures for the routine management of moral education in Middle SchoolsMethod of conventional management of moral education in middle schoolFirst, the guiding ideology:School moral education is an organic whole of the whole education work, always adhere to the school adhere to the moral education, education for this product, and actively promote the quality education, the school building efficient curriculum system of moral education, moral education, improve the sense of attraction and appeal, enhance the moral education work for through and timeliness.
