3D printing is a process of making three-dimensional objects using additive\nprocesses where layers are laid down in succession to create a complete object.\nCompanies across the globe are actively piloting and leveraging the inherent\nbenefits of 3D printing technology. Today, 3D printing is expanding\nthe landscape of supply chains and providing critical medical supplies to fight\nthe COVID-19 pandemic. This article explores 3D printingâ??s current technologies\nand trends and identifies its key benefits and advantages that shape\nthe future of many industries. Additionally, the article highlights 3D printing\napplications in different industries. Finally, the article investigates the crucial\nrolls the technology plays in filling the critical gap in the supply chains of the\nhealthcare industry during the recent pandemic....
In this paper, we consider a system of strongly coupled logistic maps involving two parameters. We classify and investigate the\nstability of its fixed points. A local bifurcation analysis of the system using center manifold theory is undertaken and then\nsupported by numerical computations. This reveals the existence of a flip and Neimarkâ??Sacker bifurcations....
This article briefly analyzes the development status of China (Chongqing) Pilot\nFree Trade Zone and Chongqing Port Logistics firstly, and then, the mechanism\nof interaction between the free trade zone economy and the logistics\ndevelopment of Chongqing Port is discussed from a qualitative perspective.\nFinally, according to the development status of Chongqing Port Logistics,\nsome countermeasures are put forward to solve its development problems\nand realize the benign interaction between the free trade zone economy and\nChongqing Port Logistics....
Enterprises are constantly experiencing higher levels of supply chain disruptions\nin their operations due to the expansion of industriesâ?? business networks.\nIt becomes very necessary for enterprises to continually assess risks in\ntheir business operations. To mitigate the adverse consequences of such potential\nsupply chain risks on the performance of enterprises, it becomes imperative\nfor Ghanaian enterprises to implement adequate supply chain risk\nmanagement strategies. The purpose of this paper is to outline potential risks\nin the supply chain network of Ghanaian enterprises and investigate the impact\nof these potential risks and supply chain risk management (SCRM)\nstrategies on enterprise performance. Data for the study was collected from\n210 enterprises in Ghana and analyzed by modeling the constructs of supply\nchain risks, supply chain risk management (SCRM) strategies and enterprise\nperformance and also measuring the complex relationships among the constructs\nusing a structural approach. The structural model result shows that,\nenterprises with distinct organizational structures dedicated to supply chain\nrisk management with the purpose of mitigating supply chain risks tend to\nperform better than their competitors. The results also indicated a negative\nassociation between supply chain risks and the performance of Ghanaian enterprises.\nThis research provides direction for managers to adopt and develop\nadequate enterprise supply chain risk register and supply chain risk management\n(SCRM) strategies to mitigate the consequences of supply chain risks in\ntheir planned business operations....
Generally, road characteristics (such as the longitudinal slope and pavement damage) have an important effect on logistics\ndistribution path, not only the vehicle fuel economy and driving safety but also the benefits and efficiency of logistics companies. It\nis necessary to explore the influence of road characteristics on logistics distribution path planning. First, a road characteristics\nevaluation value is defined to quantify road characteristics. With the application of analytic hierarchy process (AHP), the road\ncharacteristics evaluation index system with three criteria and eleven indices was built, and then the calculation of the road\ncharacteristics evaluation value is proposed based on the fuzzy comprehensive evaluation method. Secondly, a mathematical\nmodel of logistics distribution path planning is proposed, in which road characteristics and distance are comprehensively\nconsidered. Thirdly, an adaptive genetic algorithm (AGA) is presented with customized crossover operator for the solution of the\nmathematical model. Finally, through simulation by a real example, the influences of road characteristics and distance on the\noptimal distribution path are discussed, and the results show the model considering the road characteristics and distance\ncomprehensively achieves superior distribution paths to that considering the distance or road characteristics only....
