This paper discussed the methods to build up multimodal military logistics transportation networks, defined the topological structures of two-dimensional combined transportation networks without multiple edges and the expression of transportation networks’ attribute values. A route optimization model for multimodal transportation based on military supply was established, which turned out to be a high-order model due to the fact that safety attribute was a multiplicative parameter. To solve this problem, this paper proposed two improvement methods, respectively simplifying the original non-linear high- order 0-1 programming model into second-order 0-1 model and linear 0-1 model, which made it far less complicate to get the solutions. For further demonstration, this paper chose a case scenario which involved 74 nodes for simulation analysis, using Lingo 9.0 for programming to get the solutions of the high-order model, the second-order model and the linear model. The consistent results proved the models’ correctness and feasibility in getting solutions. It was specially worth noting that the improved linear 0-1 programming model was able to get real-time overall optimum solutions, demonstrating very good real-time performance, stability and solution-getting ability.

Containerization and multimodal transport are the development direction of railway cold-chain transportation. The increasing market demand also put new requirements on railway cold-chain transportation. The fact that China is a country covering vast territory with backward cold-chain transport equipment restricts the range of railway refrigerated freight transport. Therefore railway cold-chain transportation lost its comparative advantage that combined large freight volume and long transport distance. For solving this problem, railway transportation department uses 45ft integrated diesel-electric refrigerated container as cold-chain carrier, at the same time, adopts stop and refueling strategies in transit to extent continuous refrigerating time.

The signal system, playing a crucial role in ensuring operation safety of rail transit, must be evaluated to make sure its safe running. However, it lacks of the comparative research of safety assessment methods that are suitable for the key equipment of rail transit signal system. Based on the signal system of rail transit related research and safety assessment theory, several safety assessment methods, including fuzzy comprehensive method which was explored in the safety assessment of switches, have been analyzed in this paper so as to present the characteristics of these methods and applicable range and conditions.

In the trends of rail transit network development, this paper gives a brief analysis of the superiority and impact factors of the modern tram network development. On this basis the authors present three kinds of adaptation modes of the modern tram network development. These three modes respectively focus on the small and medium-sized cities groups, the new town in big cities and the ecological tourism zone. At the same time the authors conduct the case studies.

Network operation perplex train delay and passenger flow delay which are the two typical representations of delays. Several train diagram models were set up to analyze train delay propagation characteristics and passenger flow affect. The most prominent characteristics is network dynamic property, and main factors are utilization of carrying capacity, distribution of delay and location of delay. Therefore computer simulation is applied for a case study of Shanghai Metro’s Line 2 to find the influence law of these factors. Firstly, the simulation results help summarize several challenges of delay propagation for Urban Rail Transit (URT) Organization. Secondly, it is found that Operation Reliability is an important indicator of Urban Rail Transit Organization. The mutual effect between delay propagation and carrying capacity has been mainly reflected in actual URT Organization. Lastly, this paper provides URT with strategies to deal with these influence relation.

This paper focuses on the schedule design problem for liner shipping to hedge against uncertainties. As a complement of Robust Optimization, a new optimization method—Wave Optimization (WO) is proposed, which is more suitable for socioeconomic systems. Then a mixed-integer nonlinear programming model based on WO is presented to solve the vessel schedule design problem. A real-life case study is investigated and proves that the proposed model could be solved effectively and efficiently for the realistic scale problem.

In order to fully realize the potential of Urban Rail Transit (URT) system in maintaining the viability of major cities, one of the key elements—the competency of staff operating the URT system—must be managed effectively. As driverless URT systems have the ability to achieve higher efficiency while still maintaining the required safety standard, more driverless URT systems are being built and operated. When an URT becomes driverless, the operating concept of the URT will become significantly different from that of an URT with drivers as well. This has resulted in new challenges to the management of staff competency for a driverless URT system. This paper started off with discussions of the Competency Curve and then used the driverless Singapore North East Line (NEL) as a study case to examine the two main challenges faced when managing staff competency in a driverless URT context: the manual driving of a driverless train, and the driverless train control in the Operating Control Center (OCC). Strategies towards the handling of the above-mentioned new challenges were proposed based on the experiences gained on the ground.

To achieve uniform distribution of loads over three bogies, the authors use two sets of load balancing mechanisms at the underframe of car body. The practical tests show that the load balancing mechanism has two problems: low efficiency, the difference between vertical forces at both ends being equalised reaches about 25%; response latency, the force at the passive end is always slightly delayed, which affects the uniform load effect when the vehicle operates at high speeds. This paper gives the principle and stress analysis of the railway freight vehicle load balancing mechanism, and provides the methods to improve the efficiency of the mechanism.
