This paper provides a comprehensive review of urban transportation network design problems according to CiteSpace, including main problem classifications, mathematical models, and solution methods obtained from CiteSpace clusters. The attempts present the systematic picture show future directions it.

The classification of shale is commonly based on lithofacies structure, mineral content, organic carbon physical and chemical parameters, element contents. A geochemical method the compositional data proposed which divides shale, sedimentary rocks, sediments, soils into six types, named siliceous, felsic, silicate, calcsilicate, dolomitic, calcareous components, numbered from type 1 to 6, respectively. Sedimentary rocks in China, including mudstone (shale), sandstone, carbonate siliceous are...

Urban public transportation contributes greatly to sustainable urban development. An network is a complex system. It meaningful for theory and practice analyze the topological structure of an explore spatial so as mitigate prevent traffic congestion achieve sustainability. By examining Xi’an bus network, degree distribution, average path length, aggregation coefficient, betweenness centrality station were computed using models in theory. The results show that node degrees are unevenly...

The structural deficiencies of the terminal delivery path often make it main culprit urban traffic congestion and environmental pollution. Traditional studies express networks regarded them as an independent entity, ignoring endogenous role road network morphology structure. To solve this problem, paper explored spatial dependency routes in Xi'an City based on idea a bipartite graph network. A matrix paths–urban roads was constructed by abstracting paths node-set B. In addition, three...

Ship diesel engine disassembly and assembly (SDEDA) is essential for ship inspection maintenance navigation safety. The SDEDA consists of various machinery parts operations. It crucial to develop a system operations improve the efficiency (D&A). Considering “AND” “OR” relations (modeled as links) among D&A nodes), an “AND/OR” network developed extend specialized graph model sequencing problem in context education training. Then, we devised mixed-integer linear program (MILP) optimize...

Xi 'an international inland port and airport are the important fulcrums for Shaanxi province to implement strategy of "One Belt One Road" develop its export-oriented economy. Based on general development situation analyzing their similarities differences, external cause internal synergy discussed. The contents from level, tactics level business explained respectively.

The Xi'an freight hub node and operation status are sorted out.With the purpose of breaking through existing limitations adapt to development needs Silk Road Economic Belt, paper proposes a international transportation with "one center + two carriers four channels".It elaborates on aspects: demand analysis, composition, layout supporting system.It is helpful provide useful suggestions for improving strategic position hub.

Based on the theory of collaboration, this paper explores necessity collaboration between Xi’an inland port logistics and regional economy under background constructing Shaanxi free trade zone. Grey relation method is used to make an empirical study relationship economy. Study results show that there a clear correlation them. In end, puts forward some countermeasures further promote linkages, positively respond zone construction new reform opening platform. The mostly first fully use...

With the purpose of guiding Xi’an inland port from strategy perspective, this paper uses SWOT analysis to determine key factors both internal and external situation. Then quantitative by expert scoring AHP is carried out calculate strength strategic azimuth. The results show that should take advantage opportunities completely perform more positive strategies. In particular, it build up alliance at first, construct port-vicinity industrial zone information system. Lastly, intermodal...
