本文综合考虑联合收获机机械作业成本及收获作业的适时性损失，以总成本最小为目标，以最佳经济功率及最佳经济幅宽时的各种机型及其配套割台单位功率或单位幅宽所应该负担的最佳面积及所支付的费用为基础，利用整数线性规划的理论，建立了农业生产单位联合收获机选型配备模型；并利用计算机计算准确、快速的特点，编制了计算机选型配备程序。利用该程序，可以通过人机对话简洁明了的方式输入不同的有关参数，即可快速、准确地得到多方案选型配备结果，为农业生产单位联合收获机选型配备提供科学的依据。
In this paper, we consider the cost of mechanical operation of harvester and the loss of timely operation of harvesting operations. With the objective of minimizing the total cost and using the best economic power and the best economic breadth, various models and their supporting header unit power or unit Based on the theory of integer linear programming, the model of combined harvester selection and production in agricultural production units was established based on the optimal area of the width and the cost to be paid. The computer was also calculated accurately and quickly by computer Selection and preparation procedures. By using this program, different relevant parameters can be input in a concise and easy way through man-machine dialogue to obtain the results of multi-plan selection and selection quickly and accurately, which provides a scientific basis for the selection and combination of agricultural combine harvesters.
