“…The term "knowledge-based supply chain" was derived from the term "knowledge-based economy," which describes an advanced economy with a greater reliance on knowledge, information, and high skill levels, as well as an increasing need for business and government sectors to have ready access to all of these. Knowledge-based supply chains are those that make extensive use of cutting-edge technology and heavily depend on data, knowledge, information, and people skills as the cornerstone for inventive operations, and as such, are crucial to the knowledge economy's overall strategy (Yin et al, 2022).…”

“…4.0 technologies signi cantly reduce supply-demand mismatches, process hazards, and supply chain disruptions. This real-time information enables businesses to respond more quickly to supply chain interruptions and minimize risk (Yin et al, 2022). Placing supply chains online can help businesses achieve the next tier of operational performance while also saving money (Yadav et al, 2021).…”

“…According to Yin et al, (2022), emerging cutting-edge technologies like big data, arti cial and augmented intelligence, the internet of things, blockchain, and others have the potential to have a positive impact on all food supply chains and contribute to increasing food availability. Precision farming, gene editing, biological crop protection, and technologies that improve traceability from farm to fork are some examples of speci c technologies.…”

“…Sustainable management of knowledge and information about food supply chains therefore becomes crucial to ensure the survival of the world's population. According to Yin et al (2022) it is di cult to program human minds to remember every piece of information in the supply chain, especially when the information overloads. It is at this stage that the use of technology has to be embraced to improve information and knowledge management with regard to food supply chains.…”

This paper discusses the influence and relevance of cutting-edge technologies in the development of a knowledge-based supply chain to enhance food security. The application of technologies is based on the background that food supply chains require real-time monitoring and effective information flow from farm to farm with regards to food availability, preservation of quality, health, safety, and accessibility of food from production to the final user. The study used a quantitative approach and drew a sample of 65 employees and suppliers from three food manufacturing organizations (Probrands, Delta Beverages, and National Foods) that are currently using various cutting-edge technologies in Zimbabwe. Further, 80 downstream consumers were drawn from the commonly known food insecure remote areas in Zimbabwe to provide a fair review of the effectiveness of the current food supply chain system (using modern technology). Results show that a number of technologies can be effectively employed when developing a knowledge-based food supply chain. These include artificial intelligence, big data analytics, the internet of things, machine-learning, robotics, additive manufacturing, or virtual reality, among others. These technologies were found to be effective in resolving supply chain management challenges. As a result of reducing supply chain management challenges, food security was found to be improved and customer satisfaction enhanced. However, in the absence of such technologies, it was found that it is difficult to develop effective and sustainable knowledge-based food supply chains in Zimbabwe. It is recommended that all food producers, intermediaries, suppliers, consumers, and other stakeholders make use of knowledge-based food supply chains that are enhanced by different technologies to ensure food security and customer satisfaction.

“…Many studies on this topic mainly focus on the following aspects: (1) the topological characteristics of the entire network [18], such as the small-world [19,20] and scale-free [21,22] effects, which are analyzed on the basis of the classical statistical indicators [23] of complex networks, such as the average shortest path length or diameter, network efficiency, density, assortativity [24,25], etc. ; (2) the topological features or node importance [26,27] of metro stations, which are evaluated on the basis of the centrality parameters of network nodes [17], such as the degree centrality (DC) [28], betweenness centrality (BC) [29], closeness centrality (CC) [29], eigenvector centrality (EC) [8,28] and PageRank (PR) [30]; (3) the vulnerability [31][32][33][34], robustness [35][36][37] and resilience [38][39][40][41] of the metro-complex network, which are evaluated on the basis of (1) and ( 2); (4) the dynamic evolution law of a network or node, which is studied, and the rationality of the network development, which is assessed [42][43][44][45]; (5) the characteristics of the metro complex network with weighted passenger flow and traffic flow, which are analyzed [4,8,46].…”

With the prosperous development of the urban metro network, the characteristics of the topological structure and node importance are changing dynamically. Most studies focus on static comparisons, and dynamic evolution research is rarely conducted. It is necessary to track the dynamic evolution mechanism of the metro network from the perspective of development. In this paper, the Shenzhen Metro Network (SZMN) topology from 2004 to 2021 was first modeled in Space L. Five kinds of node centralities in eight periods were measured. Then, the dynamic evolution characteristics of the SZMN network topology and node centralities were compared. Finally, an improved multi-attribute decision-making method (MADM) was used to evaluate the node importance, and the spatiotemporal-evolution mechanism of the node importance was discussed qualitatively and quantitatively. The results show that, with the spatiotemporal evolution of the SZMN, the nodes became more and more intensive, and the network tended to be assortative. The different kinds of node centralities changed variously over time. Moreover, the node importance of the SZMN gradually dispersed from the core area of Chegongmiao–Futian to the direction of the Airport and Shenzhen North. The node importance evolves dynamically over time, and it is closely related to the changes in the node type, surrounding nodes and whole network environment. This study reveals the dynamic evolution mechanism of the complex topology and node importance in the SZMN, which can provide scientific suggestions and decision support for the planning, construction, operation management and resilient sustainable development of the urban metro.
