摘　　要：本文针对"统筹法"网络中总时差、节点时差、自由时差、安全时差、干扰时差、工序最早开始时间、工序最迟结束时间等经典概念,分析了这些概念存在的局限性,并对其进行了拓广,从单纯的时间领域拓广到长度领域,从不考虑方向性的时差概念拓广到考虑方向性的时差概念,等等;此外,简略表述了这些经典概念在拓广后的应用,例如,根据概念拓广后体现出来的性质,给出等效化简赶工网络的简单方法,以及计算工序排序结果的简单公式,等等。In this paper, aiming at some classical conceptions in ＂overall planning＂ network, such as total float, node float, free float, safety float, interference float, the earliest start time and the latest finish time, limitations of these conceptions are analyzed and extended from single time area to length area, and from conceptions of floats which don＇t consider direction to ones which consider direction, et al. In addi- tion,some applications of above classical conceptions are presented briefly, for instance, the properties which are reflected when those conceptions are extended, the simple method of simlifying time-cost tradeoff network equivalently, and the simple function of calculating result of scheduling.
