网络计划的进度监控及其定量分析

THE PROGRESS MONITORING OF ACTIVITY NETWORK PLANNIG AND ITS QUANTITATIVE ANALYSIS

时间紧迫的计划项目其进度的督监、记录及控制是非常必要的。本文在PERT/CPM网络计划中引入了期望进度矩阵、实际进度矩阵、进度偏差矩阵以及PERT网络进度图的概念,并介绍了这几个概念在进度的监控、评价方面的用途。

Activity net work planning has been applied widely in the various kinds of fields sincel950s' and its theory has improved constantly too.However,the research work on monitoring, reporting and controlling of activity network plan's execution are not enough.There is no a ripe method having been used in this field up to now.Today in the application of activity network technology, more and more managers find that it isn't very difficult to design and creat an initial activity network planning, but has to process the deviation between the actual progress and the expectant progress is much more difficult.So that how to remove the deviation has become a key point for application of activity network technology.Then the problem about the progress monitoring of network plan has become a new and important research project.In the article,the matrix of expectant progress,matrix of progress matrix of progress' deviation and progress plotting of PERT network are introduced into PERT/CPM network plan,and the analysis of progress monitoring procedure of PERT network progress is described.This method is a very useful tool not only for the monitoring,reporting and controlling of network plan progress, but also for the evaluation of whole engineeing's execution procedure.
