Static pickup and delivery problems: a classification scheme and survey

TLDR
A general framework to model a large collection of pickup and delivery problems, as well as a three-field classification scheme for these problems, is introduced.
Abstract
Pickup and delivery problems constitute an important class of vehicle routing problems in which objects or people have to be collected and distributed. This paper introduces a general framework to model a large collection of pickup and delivery problems, as well as a three-field classification scheme for these problems. It surveys the methods used for solving them.

A multifaceted heuristic for the orienteering problem

TL;DR: In this article, the authors presented an improved procedure based on four concepts (center of gravity, randomness, subgravity, and learning) for the orienteering problem, which is much faster and results in more nearly optimal solutions than previous procedures.

A new branching strategy for time constrained routing problems with application to backhauling

TL;DR: A new branching strategy for branch-and-bound approaches based on column generation for the vehicle routing problems with time windows that produced an average cost decrease when backhauling was permitted as compared to the cost involved when the client and the distributor routes were distinct.

Efficient solutions to some transportation problems with applications to minimizing robot arm travel

TL;DR: The authors give efficient solutions to transportation problems motivated by the following robotics problem: A robot arm has the task of rearranging m objects between n stations in the plane and needs to be moved to another station.

Analysis of an O(N2) heuristic for the single vehicle many-to-many Euclidean dial-a-ride problem

TL;DR: An O(N2) heuristic is developed to solve the single vehicle many-to-many Euclidean Dial-A-Ride problem based on the Minimum Spanning Tree of the modes of the problem, which exhibits statistical stability over a broad range of problem sizes.

A multi-start local search heuristic for ship scheduling—a computational study

TL;DR: The computational study shows that the multi-start local search method consistently returns optimal or near-optimal solutions to real-life instances of the ship scheduling problem within a reasonable amount of computation time.
