( 2 ) introduce techniques of different companies to form different schemes . after analyzing the features of various schemes in the thesis , through building up the target system of four levels and utilize technical comprehensive evaluating way to conduct technical evaluation of four schemes for the thin - type spunbond nonwoven project and get the prior sequence from schemes d , b , a to c . ( 3 ) different technical schemes have various cash circulation amounts , economic evaluation is first based on evaluating and confirming feasibility of each scheme by the single scheme finance , select and use the method of multiple schemes comparison selecting - inutual repelling type multiple schemes optimization , select introducing the scheme of d company technique as the optimum , then conduct undetermined analysis to further test and verify feasibility of schemes 阐明了辽化公司在调整产业结构和产品结构、重塑主营业务的关键时期选择建设8000吨年薄型纺粘非织造布生产装置是适宜的； ( 2 )引进不同公司的技术形成了不同的方案，论文在分析了各方案的特点后，通过建立四个层次的指标体系，运用技术综合评价的方法，对薄型纺粘非织造布项目的四个方案进行技术评价，确定了丁方案、乙方案、甲方案到丙方案的优先顺序； ( 3 )不同的技术方案有不同的现金流量，经济评价首先在单方案财务评价确认各方案可行的基础上，选用多方案比选? ?互斥型多方案选优的方法，选择引进丁公司技术的方案最优，而后，又进行了不确定性分析，进一步验证方案的可行性。
Thus the non - deterministic methods such as the information theory , time - space series and complexity are used to analyze , pick up and integrate the geological , geochemical , geopgysical and remote sensing information . at the same time , synthesis mineral resource information analysis and predication system ( smr1aps ) has been written 因而本文结合高松矿田实际情况，对信息论、时空序列、复杂性等非确定性分析方法进行了发展，并应用于地质、物探、化探、遥感信息的分析、提取和综合中，最后编制了综合矿产资源信息分析与预测系统。
According to the various influence factors of slope stability , this paper , from both the deterministc analysis and undeterministc analysis aspects , summarizes the evaluation methods of slope stability , which are commonly adopted in practical engineering , discusses the main characteristics and suitability of every evaluation methods of slope stability , finally looks forward to the study tendency to analyze and evaluate slope stability 摘要根据影响边坡稳定性的多种因素，从确定性和不确定性分析的角度，综述了工程实践中常用的边坡稳定性分析方法，评述了各种评价方法的主要特点和适用性，并展望了边坡稳定性分析研究的趋向。
It poses the understanding of goodwill evaluation ' s development in our country and the suggestion for enterprises , which practice on goodwill evaluation . the thesis characteristic is systematic and practical , i try to bring in some new ideas in this thesis , and wish these contents might help enterprises to improve their standard of goodwill evaluation 本文以系统性、可操作性为特征，力求在以下内容有所创新，如对商誉性质的解析、商誉价值构成因素的论述、割差法原理分析、提出评估商誉价值新方法? ?分割累加法、企业商誉价值与时间关系、不确定性分析引进等方面。
The third , it analyzes some question about feasibility analysis and provides some means to solve theses question . the fourth , it studies some important problem about real estate feasibility analyzing such as : the market segment and market position of real estate , consumer market and consumer buying action analyzing , the financial evaluation of real estate project , the analysis of risk of real estate project , the indefiniteness analyzing of real estate project . in the part of feasibility analyzing of s real estate project , it analyzes the feasibility of the s project from three aspects including marketing feasibility , engineering and technology feasibility , economical feasibility , then makes a conclusion of feasibility analyzing of s project , together with some suggestion to the problem of s project 第四，对房地产开发项目可行性分析中应重点关注的一些问题进行了较为深入的探讨，具体包括：准确地进行房地产市场细分与定位：房地产市场细分的准则，房地产市场定位的任务，房地产市场定位的误区与对策；认真研究消费者市场及消费者购买行为：影响消费者购买行为的因素，消费者购买决策过程分析，消费者购买行为分析，消费者分析通常应涉及的问题；科学地进行开发项目的财务评价：静态评价及其优缺点，动态评价及其优缺点；加强开发项目的风险分析：房地产开发项目风险的特点类型，风险的总体状况及变化趋势，开发项目风险的防范策略；重视开发项目的不确定性分析：盈亏平衡分析，敏感性分析，概率分析。
Through adopting a new method and analyzing massive sensitive analysis data , this thesis induces the “ uniformity ” rule in the uncertainty analysis under the same fluctuation scope condition , then through the deductive , cites a new variable named fluctuation index of eirr to represent the project ’ s ability of resisting risk 本文另辟蹊径,通过对大量敏感性分析数据的分析,归纳出在同等浮动幅度的条件下,不确定性分析中存在着“一致性”的规律;然后再通过演绎的方法,引入一个崭新的变量? ?经济内部收益率扰动参数来代表项目抵抗风险能力大小。
The main uncertain methods of the slope stability evaluation , such as fuzzy comprehension evaluation method , grey cluster evaluation method , reliability evaluation method , and neural network evaluation method , etc . are fully discussed , and their developing history and research situation are introduced in detail , and some problems which need to be studied are presented , and the studying contents iv and work achievement are introduced ( 2 )详细地评述了边坡稳定性的主要不确定性分析方法，如可靠性分析方法、模糊综合评价方法、灰色系统评价方法，以及神经网络评价方法等等。介绍了它们的发展历史和研究现状，指出了它们存在的主要问题与不足之处。在此基础上，提出了本文研究工作的思路和主要内容。
In this paper , via expounding the conceptions and the characteristics of high - tech and technical reconstruction , as well as referencing correlative theory and method of the technical - economical evaluation , it puts forward much more systemic evaluation target and builds the model of technical - economical evaluation of high - tech reconstructing traditional industry project . the model is made up of uncertainty analysis and durative analysis , technology assessment , and economic benefit of technical reconstruction project 本文通过对高新技术、技术改造等概念和特点的阐述，并参考技术经济评价的相关理论和方法，提出了更加系统的高新技术改造传统产业项目技术经济评价指标体系，建立了高新技术改造传统产业项目的技术经济评价模型，其中包括：项目的不确定性分析、可持续性分析、项目的技术评价、经济效益评价等要素。
