基于整数非线性规划的农机系统优化配备研究

Study of Farm Machinery System Optimization Based on Integration Nonlinear Program Method

针对以往农业机器系统优化配备研究存在的不足,提出了基于作业面积及收获作业天数可变的情况下,建立整数非线性规划的一般数学模型,选用适用于求解整数规划问题的粒子群算法进行求解。同时,结合实例进行分析计算,证明了该一般模型的有效性,得出农业机器系统优化配备获得整数最优解的必要性及经济性,可为当前农业企业在选择配备大功率农机具时提供一定的理论依据。

Based on the issue that the previous results of farm machinery system,the paper advanced that built nonlinear integer program model of the farm machinery system based on the case of operating area and harvest operating days are variable and used improved particle swarm optimization as the solving method of the farm machinery system.And with examples of optimized calculation to prove the validity of the general model,and concluded that agricultural machinery system optimization to obtain an integer optimal solution are necessary and economic.The results can provide some theoretical basis for the current agricultural enterprises to choice high-power farm machines.
