    摘要:

    “三夏”農(nóng)忙時節(jié),,農(nóng)機跨區(qū)作業(yè)已經(jīng)成為重要的農(nóng)業(yè)機械服務(wù)模式,可以更好地利用和配置農(nóng)機裝備,,提高農(nóng)田作業(yè)效率,。由于跨區(qū)農(nóng)機集群的區(qū)域分布性和動態(tài)時變性的特征,設(shè)計一個可靠的農(nóng)機集群維護服務(wù)網(wǎng)絡(luò)具有非常重要的意義,。本文針對動態(tài)分布的跨區(qū)農(nóng)機集群,,綜合考慮包含靜態(tài)服務(wù)站與動態(tài)服務(wù)車的運維服務(wù)網(wǎng)絡(luò)服務(wù)設(shè)施選址與服務(wù)區(qū)域劃分,建立混合整數(shù)非線性規(guī)劃的決策模型,,并設(shè)計了結(jié)合線性方法和組合Benders分解的高效算法,,以獲取靜態(tài)服務(wù)站的位置和服務(wù)范圍,同時確定各個階段動態(tài)服務(wù)車的數(shù)量和位置,。河南省的實例表明,,構(gòu)建的數(shù)學(xué)模型和求解算法可以有效解決跨區(qū)農(nóng)機裝備維護服務(wù)網(wǎng)絡(luò)設(shè)計問題,為服務(wù)設(shè)施選址和服務(wù)區(qū)域劃分提供了方法指導(dǎo),。參數(shù)敏感性分析結(jié)果表明,,最優(yōu)的動態(tài)服務(wù)車數(shù)量為26,當(dāng)動態(tài)服務(wù)車數(shù)量大于26時,,總服務(wù)成本隨著動態(tài)服務(wù)車數(shù)量的增加而增加,,并且增加幅度越來越大,。

    Abstract:

    Maintenance service network is built by the manufacturer to provide timely maintenance and ensure reliable operation for machinery. It is of great strategic significance to design a reliable maintenance service network. Especially in the “three summer” and “harvesting, ploughing and sowing” period in agriculture, cross-region operation had become an important agricultural machinery service mode, which bring a great challenge to the maintenance of agricultural machinery. Thus, focused on dynamic moving and geographical distributed agricultural machinery, the joint optimization problem of the static and dynamic service facilities location and service region districting was proposed. A novel mixed-integer nonlinear programming model-based decision model was developed, and an effective solution algorithm integrating linearization method and Benders decomposition was designed to determine the location of static service stations and dynamic service vehicles. The service region districting problem was addressed simultaneously to assign service units to these selected service stations. Finally, a real case study in Henan Province was conducted to verify the performance of the developed mathematical model and proposed solution algorithm. Computational results showed that the optimal number of dynamic service vehicles was 26 and the total service costs were increased with the increase of number of dynamic service vehicles when the number was greater than 26. 
