  Recently, unmanned aerial vehicles (UAVs), also known as drones, has emerged
as an efficient and cost-effective solution for package delivery. Especially,
drones are expected to incur lower cost, and achieve fast and environment
friendly delivery. While most of existing drone research concentrates on
surveillance applications, few works studied the drone package delivery
planning problem. Even so, the previous works only focus on the drone delivery
planning of a single supplier. In this paper, thus we propose the supplier
cooperation in drone delivery (CoDD) framework. The framework considers jointly
package assignment, supplier cooperation, and cost management. The objective of
the framework is to help suppliers minimize and achieve fair share of the cost
as well as reach a stable cooperation. The trade-off between using drones and
outsourcing package delivery to a carrier is also investigated. The performance
evaluation of the CoDD framework is conducted by using the Solomon benchmark
suite and a real Singapore dataset which evidently confirms the practical
findings.
