This paper studies a joint production scheduling and outbound distribution planning
problem in which orders are processed by several machines in series with the same …

The split delivery vehicle routing problem with two-dimensional loading constraints (2L-
SDVRP) is a complex practical problem in the field of logistics. It aims at finding the optimal …

In classical routing problems, each customer is visited exactly once. By contrast, when
allowing split deliveries, customers may be served through multiple visits. This potentially …

This study proposes a daily vehicle routing model for minimizing the total cost of
replenishing inventory within a supply chain. The first major contribution of this research is to …

We study two integer programming (IP) models for the multi-trip vehicle routing problem with
time windows, service-dependent loading times, and limited trip duration (MTVRPTW …

This study investigates a multi-depot multi-trip vehicle routing problem with time windows
and release dates, which is a practical problem in the last mile distribution operations. This …

We investigate the exact solution of the vehicle routing problem with time windows, where
multiple trips are allowed for the vehicles. In contrast to previous works in the literature, we …

This paper studies an unpaired pickup and delivery vehicle routing problem allowing for
multi-visit. The problem consists of two interacted decisions: the pairing of supply and …

The multi-trip vehicle routing problem (MTVRP) extends the well-known VRP by allowing
vehicles to perform several trips in a workday. The motivation arises from the new …

This paper proposes a tabu search algorithm for the two-echelon vehicle routing problem
with time windows and simultaneous pickup and delivery (2E-VRPTWSPD), which is a new …
