论异节拍流水施工中流水工期差异的实质

基于异节拍流水施工可以按照不窝工有间歇(即分别流水)或不间歇有窝工的形式组织,研究了异节拍流水施工中流水节拍产生两种流水工期差异的条件,及差异值与流水节拍值的关系。结果表明:流水工期差异为当m个施工段需要n道工序进行流水施工时,任意连续的3个流水节拍值中,若位于中间的流水节拍值为最小值,不窝工有间歇的流水工期(T)与不间歇有窝工的流水工期(T')的关系是T>T',并且其工期差值与3个连续流水节拍中的最小值和另一侧的流水节拍最大值的差值有关,是m-1的倍数;否则,T=T'。

Essence of Difference in Flow Duration in Different Flow Construction

On the basis of different flow construction and according to the form of non-idleness and interval or non-interval and idleness,different flow construction results are researched and the difference in two flow duration and the relationship between D-value and flow duration are also studied.The results show that the difference in flow duration is that when m construction sections and n work procedures are put into flow construction,there is takt time among any three continuous flows,and the middle takt time is the minimum.The relationship between flow duration(T) of the non-idleness and interval and the flow duration(T′) of the non-interval and idleness is that T>T′,and the D-value of them is related to the D-value between minimum of the three continuous flow takt time and the maximum from another side,which is the multiple of m-1,otherwise,T=T′.
