基于时间窗的农机资源时空调度模型

针对农田与农机资源的匹配与调度应用需求,抽象出基于时间窗的农机资源时空调度数学模型,以动态规划的思想逐步分解决策过程,完成每个决策的最优解解算,并进行模型寻优分析和复杂度分析.基于GIS等技术,开发了农机资源时空调度原型系统,可实现数据录入、模型运算、调度指令生成以及中心自动导航等功能.结合北京市某农机协会,开展了初步的应用试验.试验表明,模型可实现农机的快速、自动调度,有利于提高大型农机组织的农机管理和利用率.

Time-windows Based Temporal and Spatial Scheduling Model for Agricultural Machinery Resources

To meet the scheduling demands of dispatching the agricultural machinery to the reasonable farmlands, time-windows based temporal and spatial scheduling model for agricultural machinery resources was built, which serialized decision-making processes and got optimal solutions for each process. The prototype system was developed, which realized functions like data input, model computing, dispatching command generation, center navigation and so on. Cooperating with an agricultural association in Beijing, the system was tested in practice. The experiment results showed that the model could perform well in practice, which improved the management and working efficiency of the agricultural association.
