アメリカのエネルギー研究所であるアルゴンヌ国立研究所が、ドローン配送が省エネになるかどうかは平均風速に依存するとする研究を発表した。
この研究によると、風速が10マイル/時を超えた場合、ドローンの省エネ効果はなくなり、風速が20マイル/時を超えるとディーゼルトラックと同等のエネルギーを必要とすることが分かった。
この研究は、ドローン配送が省エネになるかどうかを比較するため、直接的なドローン配送のエネルギー消費量を地域エネルギー消費量や施設コストと比較したものである。
研究者たちは、気象条件、技術進歩、需要の不確実性などを考慮しながら、配送業界にドローン配送の可能性を示唆している。

Abstract

Drone delivery, once thought of as fictitious, is becoming a reality with the efforts of both forward-looking enterprises and supportive government policies. This emerging mode of e-commerce delivery raises many concerns. One important concern is the energy efficiency of direct delivery drones compared with conventional delivery trucks at a regional systems level. In this study, we develop and apply methods to quantify the regional energy impacts of drone delivery, then we assess these impacts and compare them with the impacts of truck delivery. To study this problem, we develop an optimization model that determines an optimal set of fulfillment centers (FCs) with variable service capacities that allow drones to make direct e-commerce deliveries. We adopt two drone delivery energy estimation models from the literature and use them as inputs to demonstrate the potential range of energy needs. We also develop another optimization model to account for the energy consumption of diesel trucks (DTs) and battery electric vehicles (BEVs). We test the models using validated simulation data for the Chicago metropolitan area in the U.S. to quantify the energy implications of these three delivery modes. For drone delivery, we further extend our analyses by considering the impact of wind speed and flight patterns. Our results show that direct delivery drones require 15.8% more energy than BEVs on an average windy day, and they need 15% more energy than DTs on a very windy day. We provide essential parameter values for reproducibility and list relevant open problems.
