Railway Network Blocking Problem: An Optimization Modeling Formulation about Flow Routing Problem

Hongpeng Ma, Yixiang Yue, Congli Hao
In this paper, we mainly study on modeling formulation for railway network blocking problem. We propose model formulation for RBP. The objective function of RBP model is to minimize the costs of flow traveling and delay for the train in marshalling station, by deciding which block is built and specifying...

A Comparative Research on the Optimal Anchor Angle of Anchor Cable Frame Project

Xiao Tong
It often happens in anchor cable projects that the beams of anchor cable fail to exert the optimal effect or even the projects fail due to the irrational design of anchorage angle. In response to this, based on the principal theoretical formula, the expression of the optimal anchorage angle was deduced,...
