本文的核心内容是港作拖轮规模的合理配置与研究。 - This paper explores the internal laws between such port production elements as the harbor tugs " disposition , the port " s production throughput and the number and time of the arrived ships ; under the framework of " the development project of qingdao harbor in five years " by qingdao government ; through collecting large amounts of statistic data ; under the premise of scientific induction , arrangement and calculation to all of the port " s production elements which affect the regular harbor tugs " disposition , especially under the premise of much statistic analysis to the arrived ships ; on the basis of the overall analysis to the qingdao harbor " s production from 1999 to 2000 ; through the analysis to the present disposition scale of the harbor tugs and the port " s production and management . additionally it predicts the change of the port " s production elements according to the total object of the port " s development in order to work out a relatively scientific calculation method for disposing the harbor tugs scientifically as well as decreasing blindness in disposing the harbor tugs , and also make the disposition scale of the harbor tugs scientific and reasonable with each passing day so as to answer the demands of the port " s production and management along with it " s development
本文是在青岛市政府关于《青岛港未来五年发展规划》的框架下，通过搜集大量的统计资料，在对青岛港1999年至2000年生产全面分析的基础上，对影响港作拖轮规模配置的港口生产各要素进行科学的归纳、整理、计算，特别是在对到港船舶的大量统计分析的前提下，通过对目前港作拖轮的配置规模与港口生产经营情况的分析，探索港作拖轮的配置与港口生产的吞吐量、到港船舶艘次数等港口生产要素间内在的规律，并根据港口发展规划的总体目标预测未来港口生产各要素的变化情况，以期能为各港口科学合理地配置港作拖轮、减少配置港作拖轮中的盲目性提出较为科学的计算方法，使港作拖轮的配置规模日趋科学、合理，满足港口生产经营及未来发展的需要。 - 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。
