统筹法是一种着眼于任务总进度的组织管理技术。它把一项复杂的任务(例如矿山工程设计任务,选矿试验研究任务,土建工程建设任务等)分解成为许多作业,绘制成统筹图,确定数学模型后进行定量的分析计算,找出紧急线路(又称关键线路)及非紧急线路的松弛度(即时差),从而对资源进行合理的计划和调配,即可以利用非紧急路线存在的时差,调用其人力、物力、财力去支援紧急线路,使整个任务如期或提前完成。 统筹法包括PERT和CPM,前者一般译作“计划协调技术”或“计划评审技术”,后者一般译作“关键线路法”。其实PERT和CPM并无根本区别,只是前者着重于时间控制,而后者着重于成本控制。后者作业时间一般是确定性的,而前者却往往是不确定性的。在后来的发展中,两者逐渐融合,即既考虑 The co-ordination law is an organizational management technique that focuses on the overall progress of the task. It decomposes a complex task (such as mine engineering design task, beneficiation experiment research task, civil engineering construction task, etc.) into many operations, draws a plan, determines the mathematical model, performs quantitative analysis and calculation, and finds emergency lines ( Also called the critical line) and non-emergency line slack (instantaneous difference), so as to make reasonable planning and deployment of resources, that is, to use the time difference existing in the non-emergency route, call its manpower, material resources, and financial resources to support emergency lines, so that The entire task is completed on schedule or ahead of schedule. The co-ordinating laws include PERT and CPM. The former is generally translated as “plan coordination technology” or “plan review technology”, and the latter is generally translated as “critical route method”. In fact, there is no fundamental difference between PERT and CPM, but the former focuses on time control while the latter focuses on cost control. The latter’s working time is generally deterministic, while the former is often uncertain. In later developments, the two gradually merged, that is, both
