| 摘 要： | 鉴于已有时差概念并不能充分反映CPM网络紧前和紧后工序时差的内在联系，文中引入三个新时差（前共后单时差，前单后共时差，双共时差）概念。针对目前工程项目管理中通用的时标网络图一早时标网络图和迟时标网络图，在路长定理的基础上，给出其理论依据，并在时差分析的基础上，随机绘出时标网络图，三个新时差的引入将有助于今后时标网络图的绘制，使网络技术的应用更具灵活性和实用性。

| Abstract: | In view of the fact that the existing concepts of float cannot reflect fully the intrinsic relation both preceding activities and succeeding activities of CPM network, three new concepts of activity floats are proposed. To the popular time-scaled network diagram-early time-scaled network diagram and late time-scaled network diagram, based on the theory of the path length theory, we give the theoretical basis, and protract the time-scaled network diagram stochastically. Three new concepts of activity floats which are put forward help to plot time-scaled network diagram, and make the applications of network more practical and feasible. |
