The purpose of this paper is to study the container transportation by rail and by road as alternative policies for carriage and to choose the effective one. A methodology to evaluate both transportation and ranking them has been developed. The Sequential Interactive Modelling for Urban Systems (SIMUS) as a tool to aid decision-making problems with multiple objectives has been applied. The methodology of the research includes two scenarios taking into account the weights of criteria -the first scenario does not use the weights of criteria and for the second one it is necessary to apply the weights which are pre-defined. The methodology of the research includes four steps. The first step defines the quantitative and qualitative criteria for assessment of container transportation. The investigated strategies for transportation that have been studied are intermodal rail transport and road transport. The weighs of criteria have been determined in the second step. They are used only in the second scenario. The third step of the research formulates the alternatives of carriage by containers and includes two ways of transportation: by container block trains and by trucks. The SIMUS method has been applied in the fourth step for ranking the variants of transportation. The method solves successive scenarios formulated as linear programming. This step involves ranking of alternatives and the choice of optimal type of transportation. The methodology is approbated for the routes Sofia-Varna from the railway and road network of Bulgaria. It was found that the technologies that include rail transport are the best variants of transportation. The methodology can be applied for assessment different types of transportation and different transport policies.

“…It is the joint coordination of multiple modes of transport by road, sea, rail, and air. It emphasizes the integration and seamless connection between transport modes [31]. Multimodal container transport uses containers as the transport unit and organically combines different modes to form continuous and comprehensive integrated cargo transportation [32].…”

“…Many scholars have conducted research from different perspectives of managing transportation activities, such as organizational management, business activities, and the impact of external risk on support transportation decisions. From the perspective of organizational management, scholars use effective cooperation of internal freight forwarders to coordinate transportation processes [35] or use external customer needs as a breakthrough Sustainability 2020, 12, 1487 5 of 26 point to establish reasonable transportation routes and methods [31] to achieve logistical coordination and minimize costs.

Logistics activities are an important source of energy consumption and environmental issues. Research conclusions and practical experience show that promoting the development of container multimodal transport is an effective way to reduce the level of carbon footprint. The key to influencing the development of container multimodal transport lies in the cooperation of all participants and links (modes of transport, transport businesses). Evaluating the synergy degree is a key step in this development process. This paper takes the whole process of container multimodal transportation as the research perspective, analyzes the operation process, and treats the process as a production system composed of four subsystems: facilities and equipment, organizational management, business operations, and information interactions. Through in-depth interviews and an analysis of the academic literature and policy documents, we establish a synergy degree evaluation index system and measurement model of container multimodal transport based on synergy theory and case studies. The research results are consistent with the actual situation. From 2015 to 2018, the synergy of container multimodal transport system of China's G port developed slowly, but generally moved in a more orderly direction.Sustainability 2020, 12, 1487 2 of 26 of cargo transportation; by 2020, the volume of port railway collection and distribution and container multimodal transport will increase significantly. Multimodal container operation is an important economic activity and plays a vital role in transportation and low-carbon development.In actual operation, logistics companies tend to choose a single mode of transport when conditions permit. The reason is that the participants and links (modes of transport, transport businesses) are not coordinated, due to the following: (1) There is a lack of effective connection between infrastructures. For example, many ports have no dedicated railway lines, which greatly increases transportation costs.(2) There is no uniform standard for equipment. The size standards of road trucks are different from the standards of railway loading units, and the conversion is very troublesome, requiring loading and unloading, resulting in increased costs. (3) The devices are not completely intelligent. The development of special railway wagons, railway dual-use trailers, and river-sea combined carriers is lagging, and the connection efficiency is low. (4) There is a lack of multimodal transport integration service providers. Due to the lack of a large logistics network platform and effective deployment, small transportation companies are blind, and there is often repeated transportation and wasting of resources. (5) Information docking and sharing are difficult. There is no uniform information exchange standard and format between enterprises, and each enterprise is an information island. In addition, there is a lack of effective connection between multiple modes of transport, and the costs of short barges, reloading, loading and unloading...

Abstract:For interaction between dry port and sea port, rail-sea multimodal transport is the main transportation and organization mode. The extended construction of corridors of rail-sea multimodal transport needed to be studied further. It will help to establish unified mechanism of transportation coordination, realize compatible standard transport rules, and promote the development of enterprises of sea and dry ports. Take Ningbo-Zhoushan sea port as an example, the options of multimodal transport corridors from Ningbo-Zhoushan to southwest areas are analyzed and optimized. In this paper, a TOPSIS decision model based on entropy weight is proposed, helping to effectively select the optimal multimodal transport plan. It is concluded that the best transport plan of 20 feet container from Ningbo-Zhoushan to Chengdu and Guiyang is the direct railway transport. The best transport plan of 20 feet container from Ningbo-Zhoushan to Kunming is the goods transported by rail from Ningbo-Zhoushan to Chongqing and then road from Chongqing to Kunming. Finally, it is suggested that promote the extension and radiation of port function and invest in the construction and operation of dry port.
