| 中文摘要:“三夏”农忙时节，农机跨区作业已经成为重要的农业机械服务模式，可以更好地利用和配置农机装备，提高农田作业效率。由于跨区农机集群的区域分布性和动态时变性的特征，设计一个可靠的农机集群维护服务网络具有非常重要的意义。本文针对动态分布的跨区农机集群，综合考虑包含静态服务站与动态服务车的运维服务网络服务设施选址与服务区域划分，建立混合整数非线性规划的决策模型，并设计了结合线性方法和组合Benders分解的高效算法，以获取静态服务站的位置和服务范围，同时确定各个阶段动态服务车的数量和位置。河南省的实例表明，构建的数学模型和求解算法可以有效解决跨区农机装备维护服务网络设计问题，为服务设施选址和服务区域划分提供了方法指导。参数敏感性分析结果表明，最优的动态服务车数量为26，当动态服务车数量大于26时，总服务成本随着动态服务车数量的增加而增加，并且增加幅度越来越大。 |

| 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. |
Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
