【摘要】 设备的年经营费(包括维简费和大修理费)与时间的关系大部分是线性关系。据此,本文利用连续贴现率、还原率并考虑连续形式的设备贬值,推导出三种形式(不考虑利息和设备贬值、只考虑利息、考虑利息和设备贬值)的设备最佳更新期连续模型,并用实例对模型进行了检验,结果令人满意。更多还原

【Abstract】 The relation between annual running cost (including maintenance and overhaul costs) and time is mostly a linear one.Based on this,three continuous models of optimal renewal interval of equipment (i.e.model not taking into account of interest and devaluation of equipment,model taking into consideration of interest only,and model considering both interest and devaluation) are established by using continuous discount rate,recovery rate and continuous devaluation of equipment.The models are checked by examples and the results are satisfactory.更多还原
