【摘要】 本文运用系统动力学方法对国产大功率拖拉机机组系统的经济效益进行了动态仿真研究。建立了经济效益的仿真模型,利用某农场的基本数据,对比了东方红75机组系统与国产大功率160机组系统在经济效益方面的差异。动态仿真结果表明,大功率160机组系统的投资回收期和成本费两项指标都优于东方红75机组系统,因而投入这种机组系统在经济上是合理的。更多还原

【Abstract】 In this paper, the dynamic simulation of the economic benefits for Chinese big-power tractor system was studied with systems dynamics. A dynamic-economic benefit model was established, and the economic benefits of the big-power tractor system 160 were compared with that of Dong-Fanghong 75 system for a state farm. The economic simulation results showed that the big-power tractor system is superior to the Dong-Fanghong 75 system in thetwo index numbers--the Recovery Time of Investment and the productioncosts. It proves that using big-power tractor system is more economic and more reasonable in state farms.更多还原
