返回为指定离散化列发现的预测存储桶的中点值。 - After generalizing the characteristic of modern equipment , the mission of equipment management and general situation of chinese equipment management , basied on two forms of equipment management - - - - - - practicality & value , the author combined quantitative & qualitative methods with example to analyze and discuss questions , especially the reasonable update & depreciation , accordingly achieving the optimization of the technical efficiency & economic benefit 0 one of emphases of the thesis is methods application of equipment reasonable update , that is starting with economic benefit to looking for reasonable using fixed number of year . the thesis used inferior - converted numeric method and rate equation which based on the theory square and combined with harbor loading machines & tugboat ' s actual facts , calculated the economic life of the same machine in order to make sure harbor machines " reasonable using fixed number of year . at the same time , the author made use of midpoint value regress method and stochastic trapeziform forecast method to calculate and analyze and gain the reasonable conclusion o the other emphases is questions of harbor equipment
本文概括介绍了现代设备的特点、设备管理的任务以及我国设备管理发展的概况后，作者从设备经济管理的两种形态? ?实物形态和价值形态出发，采取定量与定性相结合，以定量为主，结合实例进行分析与论述，对港口设备的合理更新与折旧问题进行了着重研究，从而实现设备的技术效能和经济效益的最优化。本文研究的重点之一是设备合理更新的方法应用，即从经济效益出发，来寻求设备的合理使用年限。本文结合港口装卸机械和港作拖轮的实际，运用以正方形理论为基础的低劣化数值法和费用方程两种方法，计算了同一种机械设备的经济寿命，从而确定港机合理的使用年限，同时，运用了中点值回归法和随机梯形预测法进行计算和分析，得到了合理的结论。
