This chapter developed the concept of breaking down a project into activities in order to draw its graph, or network. 这一章提出将一个工程项目分解为若干工作这一概念,其目的是便于绘制网络图。
We give the proof about the optimality criterion and describe an efficient algorithm for piecewise linear fractional programs on the network. 为进一步解决网络图上非线性目标函数的优化问题提供了依据。
