In the context of frequent public emergencies, emergency logistics distribution is particularly critical, and because unique advantages unmanned aerial vehicles (UAVs), model coordinated delivery UAVs gradually becoming an essential form distribution. However, omission start-up costs prevents cost UAV battery replacement sorting, assembly verification packages from being factored into total cost. Furthermore, most existing models focus on route optimization cost, which cannot fully reflect...

Because of their flexibility, controllability and convenience, Automated Guided Vehicles (AGV) have gradually gained popularity in intelligent manufacturing because to adaptability, controllability, simplicity. We examine the relationship between AGV scheduling tasks, charging thresholds, power consumption, order address issue how affects flexible units with multiple AGVs. Aiming promote AGVs load balance reduce times while meeting customer demands, we establish a model objective minimizing...

While previous study has confirmed significant correlation between infrastructure construction and air quality, little is known about the nature of relationship. In this paper, we intend to fill gap by using Panel Smooth Transition Regression (PSTR) model discuss nonlinear relationship transportation quality. The panel data includes 280 cities in China for period 2000-2017. We find that investment positively correlated quality when GDP per capita below RMB 7151 or number motor vehicle...

We introduce a new class of interval-valued preinvex functions termed as harmonically h-preinvex functions. establish inclusion Hermite–Hadamard for function via Riemann–Liouville fractional integrals. Further, we prove Hermite–Hadamard-type inclusions the product two In this way, these findings include several well-known results and newly obtained existing literature special cases. Moreover, applications main are demonstrated by presenting some examples.
