Research on Improving Labor Productivity in Chinese Railway Enterprises

Our research aims to summarize the implementation results of the former strategy of reducing redundant personnel and improving productivity in Chinese railway system. Based on the experience and advanced methods of foreign railway enterprises, the thesis studies the way and measures for the Chinese railway enterprises to improve the labor productivity in the new historical period and provides policy suggestions for further improving labor productivity in Chinese railway enterprises.

Memory,Identity and Cross-Cultural Communication:The Evolution of the Image of Chinese Railway Workers in Canada and the Reconstruction of Multiculturalism

International migrants confront many new challenges from the impact of global populism and geopolitics,but we also see the growth of a new identity culture.The Chinese community in Canada constructs its identity through the collective memory of the image of Chinese railway workers,and realizes the cross-cultural communication of a new identity culture in the course of the interaction of symbolic cultural practices.Since the 1980s,the image of Chinese railway workers has changed from"the indispensable evil"to"pioneers in nation-building"and"a tragic group subjected to injustice."This is a product of the collective memory of the Chinese ethnic group's pursuit of identity in Canada's multicultural reconstruction.The Chinese ethnic group has reshaped an image of Chinese railway workers that has been widely disseminated through cross-cultural means.They have aimed at gaining social acceptance and fundamental recognition of a Chinese-Canadian identity with the help of their"native cultural heritage and historical resources"in Canada.The construction of this identity culture through collective memory has consolidated the foundations of multiculturalism.

Seat inventory control methods for Chinese passenger railways

Railway seat inventory control strategies play a crucial role in the growth of profit and train load factor. The railway passenger seat inventory control problem in China was addressed. Chinese passenger railway operation features and seat inventory control practice were analyzed firstly. A dynamic demand forecasting method was introduced to forecast the coming demand in a ticket booking period. By clustering, passengers' historical ticket bookings were used to forecast the demand to come in a ticket booking period with least squares support vector machine. Three seat inventory control methods: non-nested booking limits, nested booking limits and bid-price control, were modeled under a single-fare class. Different seat inventory control methods were compared with the same demand based on ticket booking data of Train T15 from Beijing West to Guangzhou. The result shows that the dynamic non-nested booking limits control method performs the best, which gives railway operators evidence to adjust the remaining capacity in a ticket booking period.

Seismic Risk Assessment of the Railway Network of China’s Mainland

Earthquakes pose a great risk to railway systems and services around the world.In China alone,earthquakes caused 88 rail service disruptions between 2012 and 2019.Here,we present a first-of-its-kind methodology to analyze the seismic risk of a railway system using an empirically derived train service fragility curve.We demonstrate our methodology using the Chinese railway system.In doing so,we generate a set of stochastic earthquake scenarios for China based on a national-scale seismicity model.Using disruption records,we construct an empirically grounded fragility curve that relates the failure probability of train services to peak ground acceleration.By combining the simulated earthquakes,the fragility curve,and empirical train flow data from 2016,we quantitatively assess the seismic impact and the risk faced by the Chinese railway system.The maximum train trip loss could reach 2400 trips in response to a single seismic event,accounting for 34%of the national daily train trips.Due to the spatially uneven daily train flow and seismicity distribution,the seismic impact on the railway system in different seismic zones is highly heterogeneous and does not always increase when the hazard intensity increases.More specifically,the results show that the railway lines located in the Qinghai-Tibet and Xinjiang seismic zones exhibit the highest risk.The generated impact curves and the risk map provide a basis for railway planning and risk management decisions.
