Link prediction is an important issue for network evolution. For many real networks, future link prediction is the key to network development. Experience shows that improving reliability is an important trend of network evolution. Therefore, we consider it from a new perspective and propose a method for predicting new links of evolution networks. The proposed network reliability growth (NRG) model comprehensively considers the factors related to network structure, including the degree, neighbor nodes and distance. Our aim is to improve the reliability in link prediction. In experiments, we apply China high-speed railway network, China highway network and scale-free networks as examples. The results show that the proposed method has better prediction performance for different evaluation indexes. Compared with the other methods, such as CN, RA, PA, ACT, CT and NN, the proposed method has large growth rate and makes the reliability reach the maximum at first which save network construction resources, cost and improve efficiency. The proposed method tends to develop the network towards homogeneous network. In real networks, this structure with stronger stability is the goal of network construction. Therefore, our method is the best to improve network reliability quickly and effectively.

The article covers the issues of the Russian railway development as part of the supply chain. The author discusses management process specific features in respect of the Northern Railway network construction and historical aspects concerning the Russian Empire during the reign of Alexander III. Solution to this problem was to develop specific (extraordinary) mechanisms of public governance. They included a special Institute of the Commission of experts and a special form of legislative acts called the all-Merciful manifestos. The study revealed disadvantages of such autocratic governing practice for railway construction and proved inefficiency of this approach to develop controlling mechanisms.
