摘要
对于一个系统的优化,除了采用系统工程中常用的数学方法外,还可以采用对计划评审技术所对应的PERT图进行相应的调整处理,达到对系统资源分配进行优化,以提高系统效率的目的。这种方法的具体做法是:通过对PERT图中的关键路径和最短路径的长度进行调整,即通过调整这两种通路上的边所对应的资源分配,以此提高系统效率。该方法简单直观,因此在系统优化中具有较大的实用价值。
With respect to optimizing a system, apart from the common mathematical approaches in the systems engineering, the PERT diagram corresponding to program evaluation and review technique can also be applied to achieve optimization of the systems resources allocation so as to increase the systems efficiency. The concrete procedure of this method is by adjusting the lengths of the critical path and the shortest path in the PERT diagram, i.e. adjusting the resources allocation corresponding to the lines of both paths to increase the systems efficiency. With its simplicity and visibility, the great practical value is possessed in the system optimization.
