Secondly , the paper brings out problems which are need to be solved as emphases by analyzing objectively the plant ' s cost control actuality , the existing problems and its reasons . the analysis indicates that because of high dependence on planned economy , exterior factors seriously restricting the reasonable price of fuel , the electrovalence being made by exterior , the deficiency of its interior mechanism and the big random of cost control , the enthusiasm that the plant manages and controls cost independently is badly hurt . thirdly , aiming at these leading problems , applying the present cost control theory and the main cost control methods of electricity enterprises both home and abroad , the paper designs and evaluates its cost control project at these aspects of productive technology , management , logistic control , financial management and the manpower cost , and lodges corresponding cost control project of every tache 论文首先对当今国内外成本控制理论研究现状和应用现状进行了分析，包括成本性态分析、成本控制内容分析及成本控制程序与方法的分析，为论文研究打好了理论基础；其次客观全面地分析了永昌电厂成本控制的现状和存在问题及其产生原因，其中包括计划经济色彩浓厚、外部因素严重制约燃料成本的合理配比、电价确定权在外，它严重挫伤企业成本管理与控制的自主积极性，也包括企业内部机制不全、成本控制的随意性大等问题，这为本论文提出了需要重点解决的问题；然后针对永昌电厂在成本控制方面存在的主要问题，应用当今国内外成本控制的主要理论和发电企业成本控制主要方法，从生产技术、生产管理、物流控制、资金管理及人工成本等方面对永昌电厂成本控制方案进行了相对全面的设计和评价，提出相关环节的成本控制方案。
This thesis puts forward a valuation model to intangible assets valuation and offered a reference that can solve this problem this thesis adopts wacc combine capm model to confirm earning rate , uses ahp approach to confirm the weight , then confirm all kinds of intangible assets value according to their contribution in whole intangible assets , this approach is clear and easy to use 本论文针对无形资产评估这样一个系统工程提出了一个评估模型，为该问题的系统解决提供了一个可借鉴的参考。本论文采用wacc结合capm模型确定收益率，运用ahp法确定权重，根据各类无形资产在整体无形资产价值中贡献的大小，确定各类无形资产价值大小，这种方法直观明了、简洁实用。
Lwi replacement strategy replaces the lowest weight cache item , and the weight is determined by the following three factors : access frequencies of the cache item ' s projected attributes , access probability of the tuples satisfying cache item predicate on each projected attribute , and latest access time of the cache item 该策略以缓存项投影属性的访问频率、属性上满足缓存项条件的数据被访问概率、以及缓存项的最近被访问的时间确定权值，替换权值最低的项。模拟测试表明，在客户语义缓存中，该策略具有比传统lru和lfu策略更好的性能。

The author adopted the effect codfficient method and loading model established in coordination evaluation . in situation analysis of mrsd , the author adopted z - score method to make the index become the same and used the main composition analysis method to certain index power , used the number to compute . estimation future development of mrsd is important contents in the thesis , the author adopted the gray estimate polynomial the estimate index number and logarithms estimate etc different method to estimate development trended of mrsd . as the result , the author finded out the fittest estimate model in the thesis - - polynomial the estimate model 对矿区可持续发展系统发展态势的分析主要采用z - score指标归一化方法，而后利用主成分分析方法确定权重，并用归一化处理后的数值计算近年矿区可持续发展状况。对矿区可持续发展系统未来发展的预测也是本文的重要内容，本文主要采用灰色预测、多项式预测、指数和对数预测等不同方法分别对矿区的发展态势进行了预测，从中找出了最适合本文的预测模型? ?多项式预测。
This paper does preliminary and systematic research on theory and means of multiple objectives decision making under risk , and following are its mostly innovation points : 1 . giving one new notions : multiple risks and establishment of mathematical model of multiple objectives decision making under risk and the new way of assured weight through the medium of sensitivity analysis . 2 本篇论文对多目标风险型决策的理论和方法进行了初步的系统性探讨，主要做了以下几项研究工作： 1 、提出了决策中的‘多风险’的概念；建立了一般的多目标风险型决策的数学模型；给出了通过敏感性分析来确定权重的新方法。
The innovations of this thesis can be summarized into three points . firstly , the average relative velocity is introducd into a novel adptive weighted clustering algorithm as one important parameter of weight , then it increases the stability and self - adaptability of cluster head . secondly , a new approach to calculating weight is suggested by integrating subjective and objective factors . it is verified by comparison with other approaches to selecting weight . thus the velocity of weight responding to the changes of network topology is increased . finally , using a som neural network to create a classifying model enables every node to learn to identify by itself the role in manet 本文的创新点有三个:首先本文在wca和aow分簇算法的基础上,引入了平均相对移动速度作为权值重要的参数,提出了一种新的基于权值的自适应分簇算法,提高了簇头在移动中的稳定性和自适应性;其次,提出了利用主客观综合赋权法确定权重的权值计算方法,通过与其他权重选择方法比较,网络结构变化的权值响应速度得到了改进;最后,论文利用自组织特征映射神经网络建立分类模型,使得网络中的节点可以自学习地确定簇中角色。
Firstly , it introduced the import principium resolving thread and steps of analytic hierarchy process . secondly , it erected model of population modernization , which based on the steps of analytic hierarchy process . lastly , it got the maximal eigenvalue of dissymmetric matrix and corresponding eigenvector with sas , and normalized the eigenvector to get weight value 本章分为两部分，第一部介绍分析法的提出、原理以及解决问题的思路和步骤；第二部建立模型确定权重，根据层次分析法的原理和步骤，建立人口现代化指标体系的模型，运用sas求解所构造的非对称判断矩阵的最大特征值，从而得出所对应的特征向量，变形后得到权重。
Secondly , a set of assessment index system has been established . the index system is fit for the project of upgrading and revising the toll collection system in the expressway , and makes a reference for other system assessment like this . at last , this paper uses the principle of grey correlation degree , combined with ahp to determine the weight of assessment index , and according to the multifactor and multi - index of upgrading and revising toll collection system development project , put forward the grey correlation method 第二，论文针对收费系统升级改造项目这样一个系统工程提出了一套评价指标体系，为该问题的系统评估提供了一个可供借鉴的参考，第三，本文以灰色系统关联度为原理，结合采用ahp法确定权重，根据收费系统升级改造项目开发方案的多因素、多指标性，提出了项目决策的关联度法，这种决策方法直观明了、简便实用。
At the same time , the shortcomings of presently evaluation method of enterprise performance and a new idea that principal component analysis is applied to logistics enterprise are put forward . in addition , the methods of calculating index weight are mended . namely , expert grades and principal component analysis are united to determine weight in order to reflect actual achievement of logistics enterprise 武汉理工大学硕士学位论文最后，介绍了目前国内外常用的几种综合评价方法，指出了现行企业绩效评价方法的不足之处，提出了采用主成分分析方法能较好地对物流企业绩效予以评价、考核，并对主成分赋权法予以改进，即将专家打分法与主成分分析法结合起来确定权重，从而能更真实地评价物流企业的绩效。
