“…The basic idea is to select an optimal value and a worst value in the sample for each index, and construct a positive ideal solution and a negative ideal solution that do not actually exist. Taking these two solutions as the reference system, for each sample, the TOPSIS method respectively calculates its distances to the positive ideal solution and the negative ideal solution, and obtains the evaluation score based on the degree of proximity [64,65]. However, the traditional TOPSIS method uses the Euclidean distance when calculating the degree of proximity of the sample to the positive and negative ideal solutions.…”

Considering the green development initiatives vigorously promoted by China, this paper constructs an evaluation index system that covers six areas, including resource utilization, pollution control, living environment, ecological protection, circular economy, and quality of economic growth. This paper also establishes an improved comprehensive evaluation model by using the method of Vertical Projection Distance-Set Pair Analysis in order to optimize the traditional method of Technique for Order of Preference by Similarity to Ideal Solution. Based on the official data released by China, this paper quantitatively analyzes the green development level of 21 provinces in eastern and western China in the aforementioned six areas from 2005 to 2020, and makes a regional comparison between eastern and western China. The results show that the level of green development in eastern China is significantly higher than that in western China. In 2020, when the research period ends, the comprehensive evaluation values of green development in all the eastern provinces, except Hebei, are higher than 4.0; meanwhile, no province in the western region has a comprehensive evaluation value exceeding 4.0 in 2020, and there is a large gap between the eastern region and the western region in areas such as economic growth quality and pollution control. On this basis, this paper puts forward relevant suggestions in terms of the coordinated green development of the eastern and western regions of China in the future.

“…4. Topsis Method TOPSIS method developed by Hwang and Yoon in 1981 is a multi-criteria decision-making technique based on the idea of the shortest distance to the positive-ideal solution and the farthest distance to the negative-ideal solution (Marchetti and Wanke, 2020). The first step of this method is the preparation of the decision matrix.…”

“…The steps of the Topsis method are listed as follows (Marchetti and Wanke, 2020;Chen, 2019;Dutta et al, 2019;Bertolini et al 2020;Ramya and Devadas, 2019;Chakravarthi et al, 2020;Bathrinath et al, 2020;De Farias and Ferreira, 2019) Particularly wj: The weight of each j criterion, relative weight values of the normalized decision matrix elements based on purpose found towards importance given to the criteria. Then, the elements in each column of the matrix r given in the equality number 2 are multiplied by the corresponding wij value given in the equality number 3 and the matrix V shown in the equality number 4 is created.…”

This study is to determine the sustainable supplier selection criteria through the literature research and to choose the best sustainable supplier with the AHP-Topsis method. Nowadays, a sustainable supply chain has become one of the main methods of supply chain management when the growth of information about sustainability in companies bore in mind. Studies about assessment and evaluation of sustainability create the main requirement in sustainable supply chain management. In this study, Economic, social and environmental main criteria and 17 sub criteria have been determined. Weights of criteria are evaluated with methods of Analytic Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) As a result of the study, The universe of the research consists of all enterprises affiliated to Bursa Chamber of Industry and Commerce. The research sample consists of a business affiliated to Bursa Chamber of Commerce and Industry. it's been determined that the most important main criterion is "Economical", for the sub criteria, these are "Quality", "Human Rights" and "Green Production". As a result of the analysis, Supplier 4 is chosen as the one who has the highest score among all the existing suppliers of the company.

“…Combine the bulk cargo price prediction model with neural network algorithms to improve railway freight volume prediction speed and accuracy [12]. ey also combined the TOPSIS method to analyze the efficiency of bulk cargo transport in the Brazilian railway system, proposed some methods for optimizing the rail transport of bulk cargoes, and improved rail freight efficiency [13]. However, researchers' research on bulk cargoes mostly focuses on water transport, and the research on rail transport of bulk cargoes needs further innovation.…”

Due to the problems such as the excessive proportion of road transport and extreme carbon emission situation of China’s transport structure adjustment, this paper combines the fourth-party logistics with the bulk cargo green transport. It is advancing the adjustment of China’s bulk cargo transport structure using fourth-party logistics. This paper improves the particle swarm optimization algorithm to compare the integrated cost and carbon emissions of different bulk fourth-party transport networks to verify the benefits of the fourth-party logistics on bulk cargo transport networks’ cost reduction and emission reduction. The results show that using the fourth-party logistics model to promote the transfer of cargoes from road to rail can reduce the integrated cost of the transport network, reduce carbon emissions, and achieve green transport.
