When discussing the methods of goodwi11 evaluation , we point out the disadvantages of the present eva i uat i on formu i a se i ect i on and the parameter confirmation , import and deepen the theory of corporate life cycle to the work of enterprise income forecast , furthermore put forward a new model of excessive capitalized earning method on goodwill evaluation , and i i luminate the main points in the appl ication of the new model 在探讨商誉评估方法时，本文针对现有评估方法公式选择与参数确定方面的不足，引入并深化企业生命周期理论，将其应用于企业收益预测，进而提出了一种商誉评估超额收益现值法新的定量模型，并对新模型应用中的要点予以说明。
This thesis begins with the theoretical basis of this case , follows with the current situation that tian fa company faces and the background of the project , and then taking both the theoretical and practical factors into account . to make the conclusion : the investment project of 2 x 50 mw thermoelectricity cogeneration in tian fa company is feasible from the prospect of financial management , and it is risk - resistant . i use three project appraisal techniques , i . e . payback period , net present value and internal rate of return and two risk analysis techniques , i . e . sensitivity analysis and breakeven analysis 论文首先介绍了案例分析的理论依据，紧接着分析了天发公司目前面临的困境以及项目投资的有关背景，然后将理论与实际结合相结合，分析计算了项目投资的资本成本、现金流量表，应用回收期法、净现值法和内部收益率法对该投资项目的效益进行财务评价，用敏感性分析和盈亏平衡分析两种方法对项目的风险进行分析，通过分析和研究最后得出结论：天发公司2 50mw热电联产投资项目在财务上是完全可行的，并且具有相当强的抗风险能力。
The second section introduces some common methods and evaluation indexes , such as net present value , internal rate of return , payback period , profitability index , etc . the present methods and evaluation indexes are incomplete , which mainly apply to the analysis on the determinate decision . in fact , they are mono - objective and most - favored methods 第二部分，介绍了投资决策中常使用的几种指标和方法，如净现值法、内部报酬率法、投资回收期法、现值指数法等，认为这些现行的投资决策评价指标很不完善，主要适用于确定型投资决策，并且实质上是单目标最优决策方法，对多目标风险型投资决策分析很不适用，甚至会导致错误的决策。
The second part makes a general study of npv method and the real options method of oil - gas projects economic evaluation . 1 . it makes a research in - depth of the conventional economic evaluation method of oil - gas projects and gets familiar with factors of oil - gas projects 首先对油气勘探类项目的传统经济评价方法，进行深入的研究，从而熟悉油气勘探项目经济评价所需考虑的因素；其次对国内外实物期权法的应用机理、模型研究、参数的确定方法的研究进行回顾；最后对净现值法和实物期权法，进行系统的比较；第三，论述实物期权法应用原理与分析新方法的实际需求。
This article , firstly , analyzes the uncertainties in the process of investment analyses , and reveals the nature , classification and characteristics of uncertainties . secondly , the article raises the theory basis of solving the uncertainties - the theory of options and the game theory , and analyzes the possibility that using the theory of options and the game theory in the analyses of investment . thirdly , the investment projects are classified according to new standard , and then the article raises the different method for different investment projects 但是传统的投资项目可行性评估一般采用的是净现值法，这种方法认为投资项目的成本可以在投资后以某种方式收回，而不使企业蒙受损失，并且这种方法未能考虑到投资的灵活性问题，忽略了与投资项目相关的各种不确定性因素，而正是这些不确定性因素形成了投资项目的投资机会价值，因此使用传统的投资分析方法可能会造成企业项目投资价值的低估和投资不足。
Thirdly , when the three primary valuation methods ( sales comparison , replacement cost , and income approach ) are applied to the vessels valuation , how to calculate its parameter is expounded in detail , in the course of determining the replacement cost ' s parameter - trie percentage of depreciation , this thesis adopts the fuzzy overall evaluation method 然后把三种典型的评估方法：市场价格比较法、成本法、收益现值法应用到船舶评估中。详细阐述了在把三种典型评估方法应用到船舶评估时，怎样确定三种方法中的参数。在确定成本法的参数成新率时，本文采用了模糊综合评判法。
