    摘要:

    針對(duì)面向植保服務(wù)訂單的多飛防隊(duì)協(xié)同作業(yè)模式,綜合考慮訂單時(shí)間窗、病蟲(chóng)害侵染狀況、多機(jī)協(xié)同等關(guān)鍵因素,建立以作業(yè)總收益最大、作業(yè)總時(shí)長(zhǎng)最小為優(yōu)化目標(biāo)的飛防隊(duì)作業(yè)調(diào)度模型;設(shè)計(jì)了訂單優(yōu)先級(jí)排序算法和基于帶精英策略的非支配排序遺傳算法(NSGA-Ⅱ)的作業(yè)路徑規(guī)劃算法,并對(duì)調(diào)度模型進(jìn)行了求解。以陜西省武功縣植保作業(yè)為例,對(duì)飛防隊(duì)作業(yè)調(diào)度模型及算法進(jìn)行了驗(yàn)證,實(shí)驗(yàn)表明,建立的模型及算法能輸出滿足時(shí)間窗約束的Pareto最優(yōu)解集,具有良好的搜索性能以及穩(wěn)定的收斂性能。該研究可為無(wú)人機(jī)飛防隊(duì)的調(diào)配與決策分析提供科學(xué)依據(jù),為農(nóng)機(jī)智能調(diào)度系統(tǒng)開(kāi)發(fā)提供參考。

    Abstract:

    In recent years, with the development of technologies of agricultural aviation plant protection, plant protection drones was used more and more in the prevention and control of pests and diseases. Aiming at the multi-team collaborative operation mode for plant protection orders in the region, the key factors such as order time window, farmland infection status and multi-machine coordination were comprehensively considered, and a multi-objective scheduling model for UAV plant protection team with the maximum total revenue and the shortest total operation time as the optimization objective was established. The order priority sorting algorithm and the path planning algorithm based on the non-dominated sorting genetic algorithm (NSGA-Ⅱ) were designed to solve the model. A case study of plant protection operations in Wugong County, Shaanxi Province was carried out to illustrate the validity of the proposed model and algorithm. Experiments showed that the model and algorithm designed can output the Pareto optimal solution set satisfying the time window constraint, and can give reasonable transfer path and time arrangement for UAV plant protection team. Moreover, the algorithm had good search performance and stable convergence performance, which can meet the needs of real scheduling problems. At the same time, research showed that increasing the order window time was beneficial to increase the total operating income and reduce the total operation time. The research can provide a scientific basis for the deployment and decision analysis of the UAV plant protection team, and provide reference for the development of the agricultural machinery intelligent dispatching system.
