一、问题的提出 我厂有20台1982年投产的EQ140翻斗车,平均每台运行12万公里。虽然还不到大修里程,但是,这批车服役期间工期任务紧迫,施工条件相当恶劣,加上这批车液压自卸部分改装设计欠合理,质量较差,因此,动力性能明显下降,经济性能很差,车况损坏严重。 我们对这20台翻斗车的投资及投产以来历年的经济效益进行了调查统计,用经济管理的理论和方法进行计算分析和经济比较,确定了这批车的经济寿命期为4年,现在更新,经济上是合算的。 二、用计算单位生产成本平均费用法,确
First, the issue put forward I plant has 20 units put into operation in 1982 EQ140 dumpers, an average of 120,000 kilometers per run. Although less than overhaul mileage, but the deadlines during the service of these vehicles during the mission, the construction conditions are rather harsh, coupled with some of these cars hydraulic dump part of the conversion design is not reasonable, the quality is poor, so the power performance decreased significantly, the economic performance Very poor, serious damage to the car. We conducted a survey and statistics on the economic benefits of the 20 dump trucks since their investment and production started in the past years. The economic analysis and economic comparison between the theories and methods of economic management have confirmed that the economic life of these vehicles is 4 years and are now updated Economically cost-effective. Second, with the average unit cost of production costs Act, indeed
