The current global interest in improving the use of ever-scarcer natural resources calls for
the re-alignment of supply chain operations to include not only economic factors, but …

Automated guided vehicles (AGVs) are an unmanned transport system used for the
horizontal movement of materials. The dispatching and routing problem (DRP) for AGV …

This paper presents constraint programming-based solution approaches for the three-
dimensional loading capacitated vehicle routing problem (3l-CVRP) that consists of vehicle …

In this paper, we consider vehicle routing problems with backhauls and time windows
(VRPBTW). Different backhaul variants are studied, namely clustered backhauls (CB), mixed …

The vehicle routing problem (VRP) and its variants are a class of network problems that
have attracted the attention of many researchers in recent years, owing to their pragmatic …

This paper studies a particular integration of the Heterogeneous Fleet Vehicle Routing
Problem with three-dimensional loading constraints (3L-HFVRP), which considers …

Waste electrical and electronic equipment (WEEE), also known as e-waste, is one of the
most important waste streams with high recycling potential. Materials used in these products …

Abstract The Artificial Bee Colony (ABC) algorithm is widely used to achieve optimum
solution in a short time in integer-based optimization problems. However, the complexity of …

Cross-docking is a logistics strategy widely applied in numerous enterprises, where vehicle
scheduling is one of the most important factor in operational level for cost reduction. In sight …

Abstract Vehicle Routing Problem is based on the generalization of Travelling Salesman
Problem and it is a combinatorial optimization problem. Vehicle Routing Problem can have …
