TL;DR: This paper introduces a transportation resource sharing strategy to address the multi-depot green vehicle routing problem, and incorporates the time-dependency of speed as well as piecewise penalty costs for earliness and tardiness of deliveries.

TL;DR: Computational comparisons on benchmark instances indicate the superiority of Im-NSGA-II over NSGA- II and MOGA, and an empirical study in Chongqing, China confirms the practicability of the solution approach.

TL;DR: In this article, a 3D customer clustering algorithm with split load strategies is developed to reassign each customer to its favorable service provider considering multiple customer service characteristics, and a hybrid genetic algorithm with tabu search is designed to optimize the pickup and delivery routes and maximize the logistics resource utilization.

TL;DR: Wang et al. as mentioned in this paper summarized the pollution characteristics of microplastics in China's inland water systems, including their abundance, distribution, source, and key factors for microplastic pollution level.

TL;DR: Wang et al. as discussed by the authors proposed a collaborative multicenter vehicle routing problem with time windows and mixed deliveries and pickups (CMVRPTWMDP), which is a variant of the vehicle routing problems (VRP) with mixed delivery and pickups, and VRP with simultaneous deliveries and pickup and time windows.
