Abstract To investigate the impact of recycling modes on stability cross-border supply chain (SC) systems, this paper decomposes a SC system, consisting two countries with different capabilities for electronic products, such as Singapore and Vietnam, into three product-market chains (PMCs). Discrete dynamical models output rate decisions system are developed based four modes. The Nash equilibrium solutions conditions obtained via nonlinear dynamics principles; stable regions chaotic...

In this paper, an output dynamic game model of intertwined supply chains operating in two different countries is established. The Nash equilibrium point the and its stable region are obtained using nonlinear principles. complex properties system, such as stability, period-doubling bifurcations, chaos, investigated numerical simulations. Our results suggest that level system’s profits undergo bifurcation chaos with increase adjustment speed. An interesting phenomenon occurs higher tariffs...

Based on the complex network theory, we explore an express delivery system in China, which consists of two networks, namely, air (ADN) and ground (GDN). Systematic structural analysis indicates that both networks exhibit small‐world phenomenon, disassortative mixing behavior, rich‐club phenomenon. However, there are significant differences between ADN GDN terms degree distribution property community structure. On basis Barabási‐Albert model, have proposed a model incorporating features to...

The connectivity of the urban public transport network and convenience transfers between modes transit are important factors that affect whether passengers choose transport. Identifying key nodes connectivity, direct access, transfers, clarifying main restrict efficiency play roles in improving establishing a “green city”. On this premise, paper constructs two single-layer networks composite can reflect transfer relationship ‘bus–bus’, ‘metro–metro’, ‘metro–bus’ based on method Space-P....

Taking logistics time, cost, and carbon emissions as optimization objectives, air transportation is included in the cross-border paths of multimodal transportation. Considering scale effect transportation, a multiobjective model including road, water, railway, constructed. The problem along “Belt Road” regions for cities inland studied via NSGA-II method. research results show that Chengdu Xi’an should bear large number be constructed national airport-type hub. foreign destinations are...

This paper focuses on the application of higher-order and multilayer networks in identifying critical causes relationships contributing to hazardous materials transportation accidents. There were 792 accidents that occurred road from 2017 2021 which have been investigated. By considering time sequence dependency causes, causation network (HMTACN) was described using model. To investigate structure HMTACN such as importance links, divided into three layers weighted k-core decomposition: core...

Abstract We study the emergence of cooperation in an environment where players prisoner's dilemma game (PDG) not only update their strategies but also change interaction relations. Different from previous studies which according to imitation rule, this article, are updated with limited foresight. find that two absorbing states—full and full defection—can be reached, assuming can delete relations unilaterally, new created mutual consent both partners. Simulation experiments show high levels...

Artificial intelligence is an important branch of cognitive science. has been applied to medical, education, logistics and other industries, which broad prospects for development. Hotel industry uses artificial technology complete intelligent search, face recognition, combined with large data calculation planning reasonable path in warehousing. Taking China's hotel as the research object, this paper analyses application industry. In warehousing process, technologies including compile storage...

Abstract Emergence of cooperation in evolutionary prisoner's dilemma game strongly depends on the topology underlying interaction network. We explore this dependence using community networks with different levels structural heterogeneity, which are generated by a tunable upper‐bound total number links that any vertex can have. study effect structure analyzing finite population analogue replicator dynamics. find heterogeneity mediates cooperation. In low level has negative However, positive...

The Belt and Road has developed rapidly in recent years. Constructing a comprehensive traffic network is conducive to promoting the development of Road. To optimize layout network, this paper identifies important cities. First, weighted super adjacency matrix defined, which includes sea, air, railway transportation trans-shipment between these modes. With matrix, (B&RCTN) constructed. identify node cities, proposes method calculate multi-layer centrality considers inter-layer...

This paper defines the weighted super adjacency matrix based on existing matrix. paper, for first time, combines trade network, competitive and complementary network to construct multilayer innovatively interlayer connections. Based this, we build networks three major agricultural products in western region along “Belt Road”. The then proposes analytical methods, including a classification algorithm local relations comparative analysis of development priorities relations. former is used...

In hazardous materials transportation systems, accident causation analysis is important to safety. Complex network theory can be effectively used understand the causal factors of and their relationships within accidents. this paper, a higher-order method proposed establish (HMTACN), which considers sequences dependences factors. The HMTACN composed 125 first- 118 nodes that represent causes, 545 directed edges denote complex among causes. By analyzing topological properties, results show has...

In recent years, the state has issued a series of policies to encourage priority development public transport. But expanding size cities and growing population pose major challenge for transportation. this paper, we study urban bus system with non-Markovian higher-order network model considering path-dependent characteristics first time. An empirical on transport Xi'an(BT-X) was conducted. The theoretical network(THBTN) is established, improved weighted k-core decomposition method based road...

Abstract Robustness of higher‐order network (HON) with dependency is different from first‐order (FON), as the attack orders and number iterations are totally different. To measure robustness HON dependency, this study proposed new strategies on node edge failure through measuring size giant component global efficiency. And two real‐world systems hazardous materials transportation accident causation system Chinese high‐speed railway were empirically studied. Results show that more fragile to...

To investigate the dynamic complexity of chain-to-chain output decisions in a closed-loop supply chain system cross-border e-commerce (CBEC), this study decomposes into four product–market (PM) chains, based on platform’s information-sharing strategy and manufacturer’s selected logistics mode (direct mail or bonded warehouse). By combining game theory with complex systems theory, discrete models for competition among PM chains under scenarios are constructed. The Nash equilibrium solution...
