计算机辅助网络计划滚动机制的研究与实现

在网络计划系统内，根据特定的约束条件和工程的实际进度，自动压缩或延长作业的延续时间，以获得一个可接受的网络计划的新版本，是一种十分必要的机制，本文了ＨＰＰ系统的滚动机制的设计原则和实现策略，ＨＰＰ的滚动机制已在实现工程中获得应用并取得良好的效果。

Study and Realization of Rolling Mechanism of Network Plan with Computer Aid

In the network plan system a mechanism is necessary which shortens or prolongs working time antomatically so as to obtain a new acceptable network plan according to specific constraining facters and actual project progress. This paper deals with the design principles and methods of realization of the rolling mechanism in HPP system. The HPP rolling mechanism has been used in practice and satisfectory results achieved.
