“…In the paper [6], the authors proposed to modernize the traction system of a diesel locomotive by using several diesel engines. Another way to modernize the traction system is to use the traction system of a diesel locomotive with hybrid power [7,8]. In these works, the authors proposed and substantiated the feasibility of using a hybrid power system in the traction system of diesel locomotives performing shunting work at the station.…”

In this work, the structure of the traction system of a shunting diesel locomotive with hybrid power, which performs both shunting work at the station and hauling work, is proposed. In order to develop the structure of the traction system, which will work effectively in both modes of operation of the shunting diesel locomotive, an analysis of the structures of the traction systems of diesel locomotives with hybrid power, produced by the world's leading companies, is carried out. In order to choose the optimal type of storage device, an analysis of the advantages and disadvantages of supercapacitor batteries and lithium-ion batteries is carried out. On the basis of the analysis of the structures of traction systems of diesel locomotives with hybrid power of leading companies and the advantages and disadvantages of supercapacitor batteries and lithium-ion batteries, the structure of the traction system of a shunting diesel locomotive with hybrid power, which performs both shunting work at the station and hauling work, is developed. In the proposed traction system structure, each traction motor receives power from a separate traction converter. The power for powering the traction motors during shunting work is transmitted from supercapacitor batteries, when carrying out hauling work - from lithium-ion batteries. This study can be used in the design of the traction system of a new and in the modernization of an existing shunting diesel locomotive.

“…After obtaining the weights of different objective functions with the entropy weight method, the optimal-solution-solving ideal point method needs to be improved. The weights of different objective functions are added to the distance function, solving the improved distance function subject to the constraints of Equations ( 6)-( 9), as specified in Equation ( 15): (15) where X = (x 1 , x 2 , . .…”

Urbanization has aggravated the conflict between continuously increasing urban travel demands and limited supply. Moreover, the inability to expand urban roads due to previous land planning and utilization has resulted in significant traffic congestion, traffic safety issues, and environmental problems. To address these problems, this work attempted to develop a multiobjective model to optimize the passenger traffic system while considering carbon emissions, transport costs, and resource utilization. In addition, the ideal point method and entropy weight method were combined to obtain the optimal solution. Based on the operational data on traffic modes and travel data on passengers in Harbin, the northern capital of China, the proposed method was used to solve the case in Harbin. The results show that the proportion of buses increased by 1.05%, that of subways increased by 36.60%, that of taxis decreased by 11.86%, and that of private cars decreased by 25.78% after optimization. Furthermore, the analyses of the results show that the optimized passenger traffic system structure can promote the sustainable development of urban transport and demonstrate the practicality of the proposed method for solving multiobjective optimization problems. Relative to the ideal point method and genetic algorithm, the proposed method is more applicable for optimizing the passenger traffic structure in Harbin. In addition, this study explored the sensitivity of the optimization goals to the four motorized modes. The results show that subways and private cars are the key areas to prioritize in adjusting the urban passenger traffic system structure. Based on the analysis results, recommendations for the development of transportation in Harbin are given. This study provides a reference for decision-makers to formulate policies for the urban sustainable development of Harbin as well as for transportation development in other cities.
