摘要
本文利用最低成本原理(最小年度作业费用法)和Lotus 1—2—3集成软件,为呼伦贝尔盟岭北地区的国营农场建立了拖拉机及其机具系统的配备计算模型。在进行计算时,最低成本原理不仅考虑到了机组作业单位面积的能量消耗、机组作业速度、机组的田间效率以及拖拉机的牵引效率等因素,而且考虑到机组作业的成本和作业的适时性损失。利用Lotus集成软件,省略了复杂的程序编制工作,实现了输入、输出的格式化和一体化。
In this paper, the selection-calculation models of tractor and it's implement system are set up with the principle of the Least-cost(the annual Least-cost of operating machine) and Lotus 1-2-3 for state farms in the North of the Xing'an Mauntains of Hulunbel'er League. The energy requirement of operating unit on unit area, the operating speed of unit, the field efficiency of operating unit, and the drawbar efficiency of tractor are not only thought out but the annual cost of operating unit and the timeliness loss of operating' when the tractor and it's implement system are selected and calculated with the principle of the Least-cost. Making use of Lotus 1-2-3, the complex programming is omited, and the format of input/output is easy formed in the same table.
