this paper shows the incompatability of system structure of the model of the network diagram, thus realizes the demonstration that algorithm for the total float of a on n and a on a is mistaken.
本文揭示了传统网络构图模型系统结构的不相容性,从而实现了传统网络总时差的计算是错误的论证。
the basic parameters of an event are total float time, free float time, and initial time and ending time.
工作的总时差、自由时差和工作的开始与完成时间是工作的主要时间参数。
in the practical engineering processes, the amount of resources is strictly limited, so in the actual engineering, the traditional cpm can not give the correct total float and critical path.
在实际工程中工序的资源量是受到严格限制的,传统的cpm法不能给出正确的工序总时差和关键路线。
the each time parameter of construction schedule network planning in the graph may be exposed immediately, the total float and the free float of each work especially.
图上可直接展示施工进度网络计划的各时间参数,特别是各工作的总时差和自由时差。
total float for the activity is 9 days.
该项工作总时差为9天。
the total float time is one of the important time parameters for a working task, and also is the basis for ascertaining critical work and critical paths in network planning.
