作业成本在农机配备理论中的应用

The Application of Work Cost in Farm Machinery Allocation

因利用现有的农机配备理论解决具有交叉作业的问题时,约束条件多、模型庞大,计算较为繁琐,在一定程度上加大了农机配备理论研究的难度与工作量。为了探求较为简化的模型,在对原有的配备模型原理进行分析的基础上,利用动力机器和作业机具的作业成本作为判断依据,绘制农事阶段图,再依此建立配备的线形规划模型,使原模型在一定程度上得到了简化,并以实例进行验证。

Because the model of farm machinery allocation making lots of restraints when deal with the problem of cross work and making difficulty for study, The article using work cost of tractors and tools draws the farm working stage, and sets up line programming model to simple it, then testify it using examples.
