Abstract
Unmanned aerial vehicle (UAV) routing is transitioning from an emerging topic to a growing research area as the 3D flexible utilization of airspace, promogulated by UAVs, is a potential game changer in solving the urban air mobility challenge by allowing to reshape transportation and logistics in the future. This has revealed a need to classify different types of research and examine the general characteristics of the research area. This research aims to assist in identifying the main topics and emerging research streams and provides a published overview of the current state and contributions to the area of the UAV routing problem (UAVRP) and a general categorization of the vehicle routing problem (VRP) followed by a UAVRP classification with a graphical taxonomy based on the analysis of UAVRP current status. To achieve this, an analysis of the existing research contributions promulgated in this domain is conducted. This analysis is used to identify the current state of UAVRP and the gaps related to the UAVs’ flight dynamics and weather conditions, which significantly influence the fuel consumption of the UAV when modeling the UAVRP.
Highlights
Unmanned aerial vehicles (UAVs) have been the subject of immense interest in recent years and have developed into a mature technology applied in areas such as defense, search and rescue, agriculture, manufacturing, and environmental surveillance [1,2,3,4,5]
We identify the current state of UAV routing problem (UAVRP) and the challenges in current state of the general vehicle routing to address the specific nature of the UAVRP
UAV routing should be done to have a seamless flight during the operations and the required navigation control is derived from a command, which is provided by a scheduler [123,124,125,126]
Summary
Unmanned aerial vehicles (UAVs) have been the subject of immense interest in recent years and have developed into a mature technology applied in areas such as defense, search and rescue, agriculture, manufacturing, and environmental surveillance [1,2,3,4,5]. UAVs have the potential to significantly reduce the cost and time required to deliver materials as, in general, they are less expensive to maintain than traditional delivery vehicles such as trucks and can lower labor costs by performing tasks autonomously [11,12,13,14] To support this emerging area, a new problem category arises, the UAV routing problem (UAVRP). The main objectives of this paper are to identify the unique characteristics of the UAVRP and present the first overview of the current state of research. This is achieved by analyzing the existing research contributions promulgated in this domain. The majority of research has been focused on automated guided vehicles (AGVs) [25], mobile robot routing [26,27,28,29,30,31,32,33,34], or six degrees of freedom aerial robots [35], which are UAVs
