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.read more
