An Enhanced Branch-and-Price-and-Cut Algorithm for the Multi-Trip Vehicle Routing Problem with Time Windows

Hu, Hongjian; Qin, Hu; Xu, Gangyan; Huang, Nan; He, Peiyang - 2023

In this paper, we study the capacitated multi-trip vehicle routing problem with time windows (CMTVRPTW) and its use in different scenarios, which have a common feature: vehicles can make multiple trips. This feature is widely used in the real world; not only can it reduce the number of vehicles...

The Hitting Time Density for a Reflected Brownian Motion

Yang, Xuewei - 2011

Reflected Brownian motion has been played an important role in economics, finance, queueing and many other fields. In this paper, we present the explicit spectral representation for the hitting time density of the reflected Brownian motion with two-sided barriers, and give some detailed analysis...
