摘要
文章以考虑技术进步为前提,以设备的经济寿命为研究对象,引入了指数分布的技术演化模型,建立了技术进步与当前旧设备残值和未来新设备总费用之间的定量关系,提出了一个技术进步条件下无穷期限的设备更新决策模型,运用该模型分析了技术进步和其它相关参数对设备经济寿命的影响。
The economic life of equipment under technological progress was studied, and the exponential model of technological progress was introduced, and the quantitative relationships were also established between technological progress and salvage values of current old equipment and total cost of future new equipment, and a decision model of equipment replacement in infinite horizon was put forward, and the effects of technological progress and other relative parameters on the economic lives were analyzed in this paper.
