层次分析法---文献翻译888大学毕业设计(论文)文献翻译题目层次分析法院、系(部) 计算机科学与技术学院专业及班级计科0903班姓名 888 指导教师 888 日期 2013年3月Analytic Hierarchy ProcessThe Analytic Hierarchy Process (AHP) is a structured technique for helpingpeople deal with complex decisions. Rather than prescribing a "correct" decision, the AHP helps people to determine one that suits their needs and wants. Based on mathematics and psychology, it was developed by Thomas L. Saaty in the 1970s and has been extensively studied and refined since then. The AHP provides a comprehensive and rational framework for structuring a problem, for representing and quantifying its elements, for relating those elements to overall goals, and for evaluating alternative solutions. It is used throughout the world in a wide variety of decision situations, in fields such as government, business, industry, healthcare, and education.Several firms supply computer software to assist in using the process.Users of the AHP first decompose their decision problem into a hierarchy of more easily comprehended sub-problems, each of which can be analyzed independently. The elements of the hierarchy can relate to anyaspect of the decision problem—tangible or intangible, carefully measured or roughly estimated, well- or poorly-understood—anything at all that applies to the decision at hand.Once the hierarchy is built, the decision makers systematically evaluate its various elements, comparing them to one another in pairs. In making the comparisons, the decision makers can use concrete data about the elements, or they can use their judgments about the elements' relative meaning and importance. It is the essence of the AHP that human judgments, and not just the underlying information, can be used in performing the evaluations.The AHP converts these evaluations to numerical values that can be processed and compared over the entire range of the problem. A numerical weight or priority is derived for each element of the hierarchy, allowing diverse and often incommensurable elements to be compared to one another in a rational and consistent way. This capability distinguishes the AHP from other decision making techniques.In the final step of the process, numerical priorities are derivedfor each of the decision alternatives. Since these numbers represent the alternatives' relative ability to achieve the decision goal, they allow a straightforward consideration of the various courses of action.Uses and applicationsWhile it can be used by individuals working on straightforward decisions, Analytic Hierarchy Process (AHP) is most useful where teamsof people are working on complex problems, especially those with high stakes, involving human perceptionsand judgments, whose resolutions have long-term repercussions. Ithas unique advantages where important elements of the decision are difficult to quantify or compare, or where communication among team members is impeded by their different specializations, terminologies, or perspectives.Decision situations to which the AHP can be applied include:, Choice - The selection of one alternative from a given set of alternatives,usually where there are multiple decision criteria involved., Ranking - Putting a set of alternatives in order from most toleastdesirable Prioritization - Determining the relative merit of a setofalternatives, as opposed to selecting a single one or merely ranking them, Resource allocation - Apportioning resources among a set of alternatives, Benchmarking - Comparing the processes in one's own organization withthose of other best-of-breed organizations, Qualitymanagement - Dealing with the multidimensional aspects of quality and quality improvementThe applications of AHP to complex decision situations have numbered in the thousands, and have produced extensive results in problems involving planning, Resource allocation, priority setting, and selection among alternatives. Other areas have included forecasting, toreotal quality management, business process re-engineering ,quality function deployment, and the Balanced Scorecard.ManyAHP applications are never reported to the world at large, because they take place at high levels of large organizations where security and privacy considerations prohibit their disclosure. But some uses of AHP are discussed in the literature. Recently thesehave included:, Deciding how best to reduce the impact of global climate change (Fondazione Eni Enrico Mattei), Quantifying the overall quality of software system(Microsoftcorporation), Selecting university faculty(Bloomsburg University of Pennsy), Deciding where to locate offshore manufacturing plants(University ofCambridge), Assessing risk in operating cross-country prtroleumpipelines(AmericanSociety of Civil Engineers), Deciding how best to manage U.S. watersheds(U.S. Department of Agriculture)AHP is sometimes used in designing highly specific procedures for particular situations, such as the rating of buildings by historic significance. It was recently applied to a project that uses video footage to assess the condition of highways inVirginia. Highway engineers first used it to determine the optimum scope of the project, then to justify its budget to lawmakers.AHP is widely used in countries around the world. At a recent international conference on AHP, over 90 papers were presented from 19 countries, including the U.S., Germany, Japan, Chile , Malaysia, andNepal. Topics covered ranged from Establishing Payment Standards for Surgical Specialists, to Strategic TechnologyRoadmapping, to Infrastructure Reconstruction in Devastated Countries. AHP wasintroduced in China in 1982, and its use in that country has expanded greatly since then—its methods are highly compatible with the traditional Chinese decision making framework, and it has been used for many decisions in the fieldsofeconomics,energy,management,environment,traffic,agriculture, industry, and the military.Though using AHP requires no specialized academic trainning, the subject is widely taught at the university level—one AHP software provider lists over a hundredcolleges and universities among its clients. AHP is considered an important subject in many institutions of higher learning, includingschools of engineering and Graduate school of Business . AHP is also an important subject in the quality field, and is taught in many specialized courses including Six Sigma, Lean Six Sigma, and QFD.In China, nearly a hundred schools offer courses in AHP, and many doctoral students choose AHP as the subject of their research and dissertations. Over 900 papers have been published on the subject inthat country, and there is at least one Chinese scholarly journal devoted exclusively to AHP.ImplementationAs can be seen in the examples that follow, using the AHP involves the mathematical synthesis of numerous judgments about the decision problem at hand. It is not uncommon for these judgments to number in the dozens or even the hundreds. While the math can be done by hand or with a calculator, it is far more common to use one of several computerized methods for entering and synthesizing the judgments. The simplest of these involve standard spreadsheet software, while the most complex use custom software, often augmented by special devices for acquiring the judgmentsof decision makers gathered in a meeting room.Steps in using the processThe procedure for using the AHP can be summarized as:1. Model the problem as a hierarchy containing the decision goal,the alternativesfor reaching it, and the criteria for evaluating the alternatives.2. Establish priorities among the elements of the hierarchy bymaking a series ofjudgments based on pairwise comparisons of the elements. For example, whencomparing potential real-estate purchases, the investors might say they preferlocation over price and price over timing.3. Synthesize these judgments to yield a set of overall prioritiesfor the hierarchy.This would combine the investors' judgments about location, priceand timingfor properties A, B, C, and D into overall priorities for each property.4. Check the consistency of the judgments.5. Come to a final decision based on the results of this process.CriticismsThe AHP is now included in most operations research and management science textbooks, and is taught in numerous universities; it is used extensively in organizations that have carefully investigated its theoretical underpinnings. While the general consensus is that it isboth technically valid and practically useful, the method does have its critics.In the early 1990s a series of debates between critics andproponents of AHP was published in Management Science and The Journal of the Operational ResearchSociety. These debates seem to have been settled in favor of AHP.Occasional criticisms still appear. A 1997 paper examined possible flaws in the verbal (vs. numerical) scale often used in AHP pairwise comparisons. Another from the same year claimed that innocuous changesto the AHP model can introduce order where no order exists. A 2006 paper found that the addition of criteria for which all alternatives perform equally can alter the priorities of alternatives. An in-depth paper discussing the academic criticisms of AHP was published in Operations Research in2001.Most of the criticisms involve a phenomenon called rank reversal, discussed inthe following section.Rank reversalMany people hear about rank reversal and assume that there is some sort of proven principle about it that needs to be upheld in making decisions. That assumption has led to much misunderstanding of AHP and other decision making techniques. In actuality, rank reversal is a complex matter about which there are many conflicting ideas and opinions. This section offers a simplified explanation of the situation.Decision making involves ranking alternatives in terms of criteriaor attributes of those alternatives. It is an axiom of some decision theories that when new alternatives are added to a decision problem, the ranking of the old alternatives must not change. But in the real world, adding new alternatives can change the rank of the old ones. These rank reversals do not occur often, but the possibility of their occurrencehassubstantial logical implications about the methodology used to make decisions, the underlying assumptions of various decision theories, etc.A simple example will demonstrate the phenomenon of rank reversal: Consider a pretty girl in a small town. She's having a party next week, and she wants to buy a dress that will impress her guests. She visitsthe town's only dress store and goes to the rack of party dresses. There are five such dresses, and after long consideration she ranks them by desirability as follows:Rank Style Color Price1 Style A Blue $1092 Style A Green $1093 Style B Red $1194 Style C Yellow $995 Style D Off-White $149Now imagine that she enters the back room and sees the store'sentire inventory of dresses. The dresses she has looked at in Styles B, C, and D are the only ones of their kind, but there are four more StyleA dresses in green and eight more Style A dresses in blue. In the language of decision science, these dresses are copies of the existing alternatives. In our one-store small town scenario, there's a reasonable chance that one or more party guests would buy and wear one of the copies.When made aware of these new alternatives, our fashion-consciousgirl might rank her choices in a different order. Considering her great embarrassment if a guest were to wear the same dress that she did, she might rank her choices like this:OldRank Style Color PriceRank1 3 Style B Red $1192 4 Style C Yellow $993 5 Style D Off-White $1494 2 Style A Green $1095 1 Style A Blue $109Notice that the rankings of the two Style A dresses have reversed (since there are more copies of the blue dress than of the green one). Not only that, but Style A has gone from the most preferred style to the least preferred. Rank reversal has occurred. Axioms of decision theories have been violated. Scholars and researchers can cry"foul," or impugn the method by which the girl has made her choice, but there is no denying that in the world of our example, ranks havebeen reversed. There is no doubt that the reversal is due to the introduction of additional alternatives that are no different from the existing ones.The above is but one example of rank reversal. Rank reversal canalso occur when additional alternatives are added/removed that are not copies of the original alternatives (e.g., red and yellow dresses in completely different styles). Another example of rank reversal occurred in the 2000 U.S. presidential election. Ralph Nader was an 'irrelevant' alternative, in that he was dominated by both the Democrat and Republican candidates. However, since he attracted more votes from those who would have voted Democrat rather than Republican, his presence caused the ranks to reverse. Put another way, if Nader were not in the race, it is widely accepted that Al Gore would have won.There are two schools of thought about rank reversal. One maintains that new alternatives that introduce no additional attributes should not cause rank reversal under any circumstances. The other maintains that there are both situations in which rank reversal is not reasonable as well as situations where they are to be expected. The current version of the AHP can accommodate both these schools — its Ideal Mode preserves rank, while its Distributive Mode allows the ranks to change. Either mode is selected according to the problem at hand.层次分析法层次分析法(AHP)是一种帮助人们处理复杂决策的结构化技术,比起一种指定的“正确”的方法,层次分析法能帮助人们决定哪一种是更适合他们的需求。

层次分析法的概念

层次分析法的概念

层次分析法的概念层次分析法(Analytic Hierarchy Process,简称AHP)是一种多准则决策分析(Multi-Criteria Decision Analysis,简称MCDA)的方法,由美国运筹学家Thomas L. Saaty于20世纪70年代初提出。

AHP方法通过对多个准则进行层级划分和比较,并运用数学计算方法来确定各准则的重要性和不同方案的优先级,从而帮助决策者做出合理的决策。

AHP的基本思想是将复杂的决策问题分解为多个层次,从上到下逐级进行划分,形成一个层次结构模型。

在层次结构模型中,最顶层为目标层,下面的层次依次为准则层和方案层。

目标层描述了整体决策的目标,准则层描述了实现目标所需要的具体准则,方案层描述了可选方案。

每个层次都有若干个元素,分别构成了一个层次结构的树状图。

AHP方法的核心是构建准则间的判断矩阵,并计算出准则的权重。

判断矩阵用来比较和度量层次结构中的元素之间的重要性和优先级,它的维数等于层次中元素的个数,矩阵元素表示了两个元素之间的相对重要性。

决策者通过对每对元素进行两两比较,根据自己的主观判断,利用语义比例尺(由1到9的9个数值构成)对元素的相对重要性进行评价。

评价结果填入判断矩阵中,形成一个与层次结构对应的判断矩阵。

然后,通过计算判断矩阵的特征向量和最大特征值,可以得到准则的权重。

AHP方法还可以计算各个方案的优先级。

在方案层构建判断矩阵的过程中,同样可以通过两两比较不同方案,评价它们的优先级。

根据方案的判断矩阵,结合准则的权重,运用数学计算方法,可以得到每个方案的优先级权重。

这样,决策者可以根据方案的优先级权重,评估和比较各个方案的可行性和优劣程度,作出决策。

AHP方法的主要优势在于能够将复杂的决策问题进行层次化的细分,从而使决策问题更加清晰和可操作。

它考虑了决策者的主观权重评估和相对重要性比较,充分考虑了不同准则和方案之间的相互关系。

此外,AHP方法还能够处理不确定性和模糊性的问题,对决策者的专业知识和经验有较高的要求,同时也可以用来解决多个决策者之间的决策问题。

层次分析法的原理及应用

层次分析法的原理及应用

层次分析法的原理及应用层次分析法(Analytic Hierarchy Process,简称AHP)是一种定量分析方法,用于解决决策问题,其原理主要基于层次结构和逐级比较的思想。

AHP通过将决策问题分解为多个层次,设立目标层、准则层和方案层,并通过对层次中各元素进行两两比较和权重计算,从而得出最优方案。

AHP的基本原理如下:1.定义层次结构:将复杂的决策问题分解为目标、准则和方案三个层次。

目标是最终要达到的结果,准则是达到目标所需要满足的条件,方案是实现准则的具体行动或选择。

2.建立判断矩阵:通过两两比较的方式,将每个准则和方案与其他准则和方案进行比较,得出相对重要性的判断矩阵。

在比较过程中,根据专家判断,使用1到9的尺度进行评分。

例如,如果A相对于B很重要,则评分为9,如果A和B相等重要,则评分为13.计算权重:根据判断矩阵,通过特征向量法或特征值法计算每个准则和方案的权重。

特征向量法是将判断矩阵的每一列的平均值作为权重,特征值法是通过计算判断矩阵的最大特征值和特征向量得到权重。

4.一致性检验:通过计算判断矩阵的一致性比率和一致性指标,判断专家意见的一致性。

一致性比率越接近0,说明意见越一致,一致性指标小于0.1时才认为专家意见具有可接受的一致性。

5.综合评价:根据权重和准则的得分,计算每个方案的综合得分,从而选择出最优方案。

1.投资决策:在投资决策中,可以将投资目标、收益预期、风险、投资周期等因素作为准则,不同投资方案作为方案,通过层次分析法计算出最优投资方案。

2.供应商选择:在供应链管理中,可以将供货能力、产品质量、价格等因素作为准则,不同供应商作为方案,通过层次分析法评估供应商的综合能力,选择最合适的供应商。

3.项目评估:在项目管理中,可以将项目目标、成本、资源需求等因素作为准则,不同项目方案作为方案,通过层次分析法评估项目的可行性和优劣。

4.策略制定:在战略管理中,可以将市场需求、竞争优势、组织能力等因素作为准则,不同战略方案作为方案,通过层次分析法制定最佳战略。

层次分析法原理

层次分析法原理

层次分析法原理层次分析法(Analytic Hierarchy Process,AHP)是一种多准则决策方法,由美国学者托马斯·塞蒂(Thomas L. Saaty)于20世纪70年代提出。

它是一种定性和定量相结合的分析方法,适用于处理复杂的决策问题。

层次分析法原理主要基于对不同层次的因素进行比较和权重分配,从而找到最优的决策方案。

首先,层次分析法将决策问题分解为一个层次结构,包括目标层、准则层和方案层。

在这个层次结构中,目标层是最终要达到的目标,准则层是影响目标实现的因素,方案层是可供选择的解决方案。

通过构建这样的层次结构,可以清晰地理解问题的复杂性,有助于分析和决策。

其次,层次分析法通过构建判断矩阵来比较不同层次的因素之间的重要性。

在判断矩阵中,决策者需要对两两因素进行比较,根据其重要性进行打分。

通过对比较结果进行一致性检验,可以确保决策者的判断是合理和一致的。

然后,层次分析法利用特征向量法对判断矩阵进行特征值分解,从而计算出每个因素的权重。

特征向量法是一种数学方法,可以找到最大特征值对应的特征向量,从而得到每个因素的权重。

通过这种方法,可以 quantitatively 来确定不同因素的重要性,为后续的决策提供依据。

最后,层次分析法利用权重分配来进行决策。

在确定了各个因素的权重之后,可以对不同方案进行评价和比较,从而选择出最优的决策方案。

通过层次分析法,可以将主观的定性因素转化为客观的定量分析,有助于决策者做出科学、合理的决策。

总的来说,层次分析法原理是通过将复杂的决策问题分解为层次结构,通过比较和权重分配来找到最优的决策方案。

它结合了定性和定量分析,可以应用于各种复杂的决策问题,如投资决策、项目选择、供应商评价等。

层次分析法在实际应用中已经得到了广泛的应用,成为了一种重要的决策工具。

在决策过程中,层次分析法可以帮助决策者充分考虑各种因素的重要性,避免主观偏见和盲目决策。

它能够将决策问题分解为易于理解和处理的部分,有助于决策者深入分析和思考。

层次分析法分析短语引言层次分析法(Analytic Hierarchy Process,AHP)是一种决策分析方法,用于处理复杂的多目标决策问题。

它可以帮助我们在众多因素之间进行权衡和选择,并提供一个合理可行的决策结果。

本文将介绍如何使用层次分析法来分析短语,以解决语义层次关系和权重问题。

什么是层次分析法?层次分析法是一种结构化的决策方法,它将复杂的多目标问题分解为一系列层次结构,从而更容易理解和处理。

在AHP中,问题被划分为三个主要元素:目标、准则和方案,每个元素又可以进一步细分为子准则和子方案。

通过对这些元素之间的比较和权重分配,可以得出一个整体的评估结果。

AHP的基本原理AHP的基本原理是使用专家判断和主观逻辑来确定不同因素之间的相对重要性。

它的核心思想是通过构造一个层次结构,然后使用成对比较的方法来确定每个元素的权重。

具体步骤如下:1.定义问题的层次结构:确定目标、准则和方案,并将它们组织成一个层次结构。

2.成对比较:用判断矩阵对相邻元素进行两两比较,评估它们之间的重要性。

比较的标准可以是数量、质量、重要性等。

3.构造判断矩阵:将成对比较的结果填入判断矩阵中。

4.求解权重:通过计算特征向量和特征值,求解判断矩阵的最大特征值和对应的特征向量。

5.一致性检验:使用一致性指标来检验判断矩阵的一致性,确保判断矩阵的可靠性。

In this research effort, evaluation (give second opinions) of another’s assessment of goal is carrie d out, wherein, the criteria assessment is different while keeping the alternatives assessment with respect to each criteria constant, to test if the priority vector of the alternatives is same or different.Keywords: AHP process, subjectivity, pair-wise assessments.1. IntroductionMaking decisions involve evaluating the available alternatives and choosing the right one that meets a desired objective. Underlying assumption is our ability to compare, and measure or assess the value of these alternatives with the respect to the goal at hand. It is one of main functions and responsibilities of senior management in organizations. Decision-making is a fundamental process that is integral in everything we do (Saaty, 2004). It is not surprising to know that one of the main goals of education is to help students/participants in the study to make better decisions and increase objectivity in making such decisions. However, subjectivity cannot be completely eliminated because we interpret and make inferences based on objective assessments of the data.Analytical Hierarchy Process, a decision-making methodology developed by Saaty (1987) is an attempt in this direction. AHP can be used in any situation where the presence of multiple influencing factors and decision criteria make it difficult to understand the interactions among them intuitively. In such cases AHP offers a structured approach to reduce the complexity and help us in making a decision objectively.Saaty (2004) argues that subjective judgments using qualitative parameters are not necessarily inferior to physical quantitative measures. He contends that physical scale measurements only help in interpretation and in our understanding and use of the things that we already know how to measure.Although, AHP is practiced in industry and academics, it presents a few concerns and opportunities for further research. One of the concerns is that subjectivity. Although subjectivity cannot be eliminated completely, with better analysis, objectivity can be improved. In this paper, using the AHP methodology, we propose to evaluate or provide second opinion of another person’s assessment of a goal to improve objectivity. With this approach, the second opinion of the criteria assessment is different while keeping the alternatives assessment with respect to each criteria the same and test if the priority vector of the alternatives is same or different.The remainder of the paper presents a brief literature review about the analytical hierarchy process followed by hypothesis of the study and research design. Following these, we present data presentation and analysis. We conclude the paper with limitations and future scope.2. Literature ReviewThe primary objective of AHP is to classify a number of alternatives by considering a given set of qualitative and quantitative criteria and using pair-wise comparisons/judgments. AHP results in a hierarchical leveling of the quality determinants, where the upper hierarchy level is the goal of the decision process, the next level defines the selection criteria which can be further subdivided into sub criteria at lower hierarchy levels and, finally, the bottom level presents the alternative decisions.Analytic Hierarchy Process (AHP) is one of the multi-criteria decision making methods that was originally developed by Saaty (1987). It is a method to derive ratio scales from paired comparisons to determine relative weights and use them for evaluating alternatives. The input can be obtained from actual measurement such as price and weight or from subjective opinion such as satisfaction feelings and preference. AHP has a provision for a small inconsistency (10%) in judgment because it is difficult to be absolutely consistent. The ratio scales are derived from the principal eigenvectors and the consistency index is derived from the principal eigenvector value (Saaty, 2008).It is well known that AHP is associated with large computing and subjectivity (Rang-guo & Yan-ni, 2004). In an effort to improve quality of decisions, Stern, Meherez, and Hadad (2000) suggested a hybrid approach of using data envelopment analysis (DEA) and AHP to take best of both and avoid pitfalls of each method. The Peters-Zelewski (2008) paper looks at a discussion of the pitfalls of AHP from understanding differences between relative versus absolute measurements, clustering of direct measurements, and integrated view of inputs and outputs.Considering the above research findings, our research objective is to understand the inherent subjectivity of pair-wise comparisons via the tool of reciprocal assessments. And to overcome the subjectivity issue, we propose to use research methodology involving evaluation of second opinion of another person’s assessment of a goal to improve objectivity.3. Hypotheses/ObjectivesOur research goal is to improve the quality of decision using AHP by inserting second opinion of a person’s assessment to examine variations in choosing the alternative.4. Research Design/MethodologyIn this research study, we found that without a strong understanding of the AHP technique, the respondents in the pilot survey found it difficult to provide consistent judgment. Hence, we have sought four pair-wise comparisons for the criteria table and two for each of the project judgments (for every criteria) to derive a consistent set ofall pair-wise comparisons..Using literature review, Rich (2012), Sulemani (2009), Hibner (2011) and interviews with Scrum Masters, we have derived a prioritized list of factors influencing the success for Scrum projects. Five factors were identified, for assessing their influence and impact on success, Scrum process understanding/compliance (Factor 1), Clarity of Scrum Projects i.e. roles and responsibilities(Factor 2), Effectiveness of Scrum Master(Factor 3),Customer–Degree of Product Owner involvement (Factor 4), Team collaborative environment (Factor 5)..The survey questionnaire included two components: general profile (role in project, years of experience, educational qualification, number of scrum projects, number of scrum masters, type of project, size of organization, and part 2 included AHP parameters for gauging the influence of various factors (mentioned above) on success or failure in Scrum project..For the pair-wise comparisons we used a verbal scale of moderate, strong, very strong and extreme and neutral and converted them into a numerical scale of 2,4,6,8 respectively. The pair-wise comparisons for two respondents are shown in Appendix.对层次分析法AHP模型优势的进一步分析伊扎卡;拉比的摘要本文探讨了层次分析法AHP分析模型的优势,即可以提高企业管理人员决策过程的质量。

层次分析方法范文

层次分析方法范文

层次分析方法范文层次分析方法(Analytic Hierarchy Process,AHP)是一种多属性决策分析方法,它最初由美国运筹学家托马斯·L·赛蒂(Thomas L. Saaty)于1970年提出,并于1980年代得到了广泛应用。

该方法将任务分解为一系列决策层次,在每个层次上比较和权衡不同的因素,并根据这些因素的重要性进行决策。

AHP的基本思想是通过对决策层次结构进行定量化的评估,将主观的判断转化为数值化的数据,从而建立了数学模型,帮助决策者做出理性的决策。

在AHP中,决策层次结构是由目标层、准则层和方案层组成的。

目标层代表决策的最终目标,准则层代表实现目标所需的评价标准,而方案层则代表用来实现目标的各种备选方案。

AHP的核心是建立一个判断矩阵,通过对不同因素的两两比较,得出它们之间的重要程度。

这个比较可以通过两两对比来进行,也可以通过用专家进行问卷调查来获取。

在两两比较的过程中,赛蒂提出了一套尺度,被称为AHP尺度。

这个尺度将因素的重要性评价划分为9个级别,从1(无差别)到9(极其重要),同时还有中间的数值用来描述两个因素之间的相对重要性。

得到判断矩阵后,可以通过特征值法来计算出每个因素的权重。

最终,利用这些权重,可以进行综合评价和决策。

AHP方法适用于多目标、多因素的决策问题,特别是当决策者需要综合考虑不同因素的重要性时,它能够提供一种有效的决策支持方法。

它在工业、经济、管理等领域有广泛的应用,例如项目选择、供应商评估、产品设计等。

AHP方法的优点包括:易于理解和实施、可以处理多个目标和因素、能够反映决策者的主观权重和偏好、可以适应不同的决策层次结构等。

然而,AHP方法也存在一些问题和局限性。

首先,它需要决策者进行大量的两两对比和数值评价,这对于一些复杂的决策问题来说可能是困难的。

其次,AHP方法的结果高度依赖于判断矩阵的构造,如果判断矩阵存在误差或者不一致性,可能会导致不准确的决策结果。

目前有很多方法可用于信号降噪,如中值滤波,低通滤波,傅立叶变换等,但它们都滤掉了信号细节中的有用部分。

传统的信号去噪方法以信号的平稳性为前提,仅从时域或频域分别给出统计平均结果。

更多的实践证明,经典的方法基于傅里叶变换的滤波,并不能对非平稳信号进行有效的分析和处理,去噪效果已不能很好地满足工程应用发展的要求。

常用的硬阈值法则和软阈值法则采用设置高频小波系数为零的方法从信号中滤除噪声。

实践证明,这些小波阈值去噪方法具有近似优化特性,在非平稳信号领域中具有良好表现。

小波理论是在傅立叶变换和短时傅立叶变换的基础上发展起来的,它具有多分辨分析的特点,在时域和频域上都具有表征信号局部特征的能力,是信号时频分析的优良工具。

小波变换具有多分辨性、时频局部化特性及计算的快速性等属性,这使得小波变换在地球物理领域有着广泛的应用。

随着技术的发展,小波包分析(Wavelet Packet Analysis)方法产生并发展起来,小波包分析是小波分析的拓展,具有十分广泛的应用价值。

它能够为信号提供一种更加精细的分析方法,它将频带进行多层次划分,对离散小波变换没有细分的高频部分进一步分析,并能够根据被分析信号的特征,自适应选择相应的频带,使之与信号匹配,从而提高了时频分辨率。

利用小波包分析进行信号降噪,一种直观而有效的小波包去噪方法就是直接对小波包分解系数取阈值,选择相关的滤波因子,利用保留下来的系数进行信号的重构,最终达到降噪的目的。

英文原文Multi-criteria selection of electric power plants using analytical hierarchy processAbstractThis paper uses analytical hierarchy process (AHP) methodology to perform a comparison between the different electricity power production options in Jordan. The systems which were considered, in addition to fossil fuel power plants, are nuclear, solar,wind, and hydro-power. Results on cost to benefit ratios show that solar, wind, end hydro-power may be the best alternatives for electric power production. Nuclear electricity turns out to be the worst choice, followed by fossil fuel electric power.1. IntroductionJordan is a non-oil producing Middle-Eastern country. It relies heavily on importing oil from neighboring countries. Most of the electric power that is generated to serve different sectors of the country is produced from power plants that use fossil fuel. This fuel is either totally imported such as petroleum hydrocarbon fuel, or partially local (only with small percentage) such as natural gas. The 1996 electrical energy consumption in Jordan reached a value of 6000 GWh. About 93% of his amount was produced by the National Electric Power Company (NEPCO) which is the main electricity supplier in the country [1]. Other options or alternatives of energy sources for electric power generation must tee considered. These options may include nuclear, solar, wind, or hydro-electric energies. The Jordanian experience with electricity generation using solar and windenergy technology has been on the small and experimental scale. These renewable energy systems were utilized in mostly remote areas of Jordan. They are used to generate electric power for individual application such as clinics, lighting, and educational television sets. The remote village of Jurf Eldaraweesh located in the Jordan desert of a population of 600, is the best example [2]. The necessary electrical energy is totally supplied by solar and wind energy conversion systems.In this paper, oil-fired power plants in addition to other alternatives are being evaluated. The other alternatives include nuclear, solar, wind and hydro-power. A brief description of various power plant technologies will be presented. Using a decision-support system through a multiple criteria analysis, such as AHP, an attempt will be made to assist decision makers to evaluate the use of the above technologies which can be most suitable for electrical power production in Jordan.2. Fossil-fuel electrical power plantsIn general, fossil fuels are non-renewable. They originate from the earth as a result of decomposition and chemical conversion of organic materials. They come in three organic forms: (1) solid, e.g. coal and oil shale; (2) liquid, e.g. most petroleum products, and (3) gas, e.g. natural gas. Coal represents the largest fossil-fuel energy resource in electric power generation [3,4]. Oil shale is a fossil fuel that exists in Jordan in abundance, but with unattractive physical properties. First, like all oil shales, it has a low heating value due to the high ash content [5]. Secondly, the Jordanian oil shale has sulfur contents, ranging 4–6% [6]. Because of low prices of petroleum world wide the utilization of solid fossil fuels, such as oil shale, cannot be feasible at the time being.Therefore, oil shale power plants can not be considered to be competitive [3]. Petroleum and natural gas are the main fuels used for the electric power generation in Jordan in addition to small hydro-powered electricity generation plants. Table 1 represents the existing electrical power plants in Jordan [1].3. Electricity power production using solar energySince the 1970s solar energy has received the greatest attention of all renewable energy sources all over the world. Many regard it as the solution for cleaner environment and may be the alternative to fossil and nuclear fuels. Thus, solar energy has been the object for production of electrical power. Many studies and experiences have shown that solar thermal power plants are one of the most economic forms of solar electricity generation. Solar energy can be converted into electricity by photovoltaic cells, but this process is mostly convenient and suitable for small applications only. Stand alone photovoltaic power systems were proposed for electrification of remote areas of which they are located outside the electricity grid-connection supply system [7]. On the other hand, solar energy can be converted into thermal energy by means of solar collectors or concentrators. A working fluid is used to convert the thermal energy into mechanical energy which is then converted into electricity. Unlike photovoltaics, large amounts of electrical power can be generated from such plants. The types of receivers that can be seriously considered are: (1) central receivers, (2) dispersed or distributed receivers and (3) solar ponds. Like most countries of the Middle East, Jordan enjoys long periods of sunshine. The local weather has over 300 cloudless days per year. Future technology suggests that the Dead Sea itself can be used as 450 km2 solar lake, operating a 2500 MWpower plant [8]. In a recent study, the potential of using the Dead Sea as a large natural solar pond for generation of electricity in Jordan was explored [9]. Kribus et al. [10] have shown new solar power plant concept by incorporating new developments of solar power optics, high performance air receivers, and solar-to-gas turbine interface. In terms of economical point of view, Kolb [11] found hybrid power towers to be superior to solar-only plants with the same field size. There is a number of solar thermal power plants in operation around the world. They are found to be one of the most economical systems for generating electricity [12,13]. Recently, the co-generation of electricity and potable water by utilization of solar energy was carried out [14,15]. This kind of system looks attractive in remote areas where both water is scares and electricity grid is not available. The system is capable of producing 30 MWe or more.4. Electrical power production using wind energyIt is very well established that wind energy resource is large and globally widespread. For different applications, it is clear that wind energy can be competitive in many locations [16–18]. Wind energy can be used in many applications such as water pumping [19], and water desalination [20]. It can also be used for the electrical power generation using wind energy conversion system [21]. Wind power is expected to be one of the least expensive forms of new electrical generation in the twenty-first century [22].With global efforts to become tough on fossil fuel related energy systems and to reduce the emissions of CO2 significantly, this will most likely introduce lower cost wind systems. For example, large wind power plants at good wind sites using emerging technologies can deliver electricity into utility grid at low prices that are becomingcompetitive with those of conventional power generation. Wind power plants can use hundreds of wind turbines that range in size from 50 to 500 kW each located in some remote areas. The plant’s computerized and control center operates similar to fossil fuel plants, except it does not have to be in sight of turbines. In a recent study a model of wind power plant for isolated location was presented [23]. Increases in the prices of fuel and cost of fossil fuel plants and in relying less on non-renewable energy resources, decrease the value and cost of wind power generation systems significantly [24,25].There are number of sites in Jordan with potentially high wind speeds, that can be utilized for this purpose [26,27]. Habali et al. [27] have presented an evaluation of wind energy in Jordan and its application for electrical power generation. A total of 11 wind sites were considered covering the entire country. The three most potential sites in Jordan are found to be Ras Muneef, Mafraq, and Aqaba. They have wind speeds that range from 4 to 23 ms throughout 80% of the whole year.5. Hydro-electric power plantsHydro-electric power plants can provide a basis for evaluating the potential of renewable sources of energy. When compared to other thermal power plants, they are found to be conventional and reliable. Some countries utilize this form of free natural energy into useful type of electrical power. For example, 11% of the electric power produced in the USA was provided by hydro-electric power [4]. Egypt and Turkey, countries of this region, also utilize this type of power for generating electricity at low costs.A number of studies were involved in utilizing hydro-power in Jordan for thepurpose of electricity production [28], water desalination [29,30], and both electricity production and water desalination [8,31]. These studies, mainly, considered the linkage of Red and Dead Seas with a canal to generate hydro-power. The Dead Sea is about 400 m below sea level (BSL), it is roughly 200 km to the north of the Gulf of Aqaba. It is an extension of the Red Sea. The Dead Sea has no outlet; its water level is a function of inflow and evaporation of water. For thousands of years the Dead Sea maintained an equilibrium with the annual inflow and evaporation of water. This resulted in a constant sea level. For example, in 1930 the surface of the Dead Sea was measured at its historical elevation of about 390 m BSL. The Jordan River is considered to be the main tributary of the Dead Sea. Over the years due to increase in population and agricultural development, water was diverted for irrigation in the Jordan Valley and neighboring countries. Therefore, its elevation was forced to drop, drastically; in 1993 it was 408 m BSL. To halt this trend, it will be necessary to introduce a substantial amount of new water to the sea. Sea water from the Red Sea can be used as a source of wafer needed for diversion into the Dead Sea. This diversion can be used to either maintain the sea at its current level and thus stop its dropping, or even to bring it back to its historical level. The power obtained from such process can be used to generate electricity and allow even more fresh water to be diverted from the Jordan River.6. Nuclear power plantsIt is very well known fact that for those countries that rely on but do not have oil, nuclear power becomes a strategic as well as economic necessity [3]. Nuclear power plants can pay for their capital cost in a few short years. Thus, a less expensive electricpower can be produced without relying on importing foreign oil, or at least the reduction in oil import. Some believe that one day oil will be depleted, and nuclear power becomes a must. Therefore, it is important to start this technology now in order to assure the country would not be left behind when the time comes to have to use nuclear technology.Nuclear electricity offers an advantage from an environmental point of view and air pollution. It has less environmental problems that are associated with oil-fired power plants. Thus, nuclear power is bound to become the choice of power for the future. There are some difficulties that are associated with nuclear power, namely, waste disposal and safety. If this kind of energy becomes popular in most countries around the world, solutions to these problem become a must and thus be found.7. The analytic hierarchy processThe analytic hierarchy process (AHP), which was developed by Saaty [32], has been an effective tool in structuring and modeling multi-objective problems. For example, it has been applied to business decisions [33], selection of areas of research and development programs [34], real estate investments [32], water policies [35], and water desalination technologies [29]. AHP can assist decision makers to evaluate a problem in the form of a hierarchy of references through a series of pairwise comparisons of relative criteria. Briefly, relative weights are determined through pairwise comparison. The method can be applied by breaking down the unstructured complex scorecard problems into component parts. Hierarchical orders are then arranged by forming value tree structures. Subjective judgments on the relative importance of each part are representedby assigning numerical values; the numerical values are selected in accordance to Fig. 1. These judgments are then synthesized in the use of eigenvectors to determine which variables have the highest priority.The decision regarding the selection of an optimum system for electricity power generation in Jordan was evaluated according to benefits and costs. Cost-tobenefit analysis is obtained by separating costs from benefits and structuring separate hierarchies for benefits and costs. They were constructed as shown in Figs. 2 and 3. The overall objective (goal) for both hierarchies was to select an optimum system (i.e. level1). Fig. 2 shows the cost hierarchy. The cost criteria at level 2 are cost of fuel, hardware cost, maintenance and service, auxiliary system, and environmental constraints.Fig. 3 presents the benefit hierarchy, it includes all possible benefits that may be derived from the various electrical power generation power plants, as applied to Jordan. Level 1 of Fig. 3 is the selection of the optimum system in terms of benefits. The benefit criteria at level 2 are the efficiency of the system, its reliability, its safety, availability of the fuel used in the system, its effect on national economy, and social benefits.The third level of the cost and benefit hierarchies represents the various technologies or alternatives which are going to be considered for electrical power production in Jordan. In addition to fossil fuel fired power plants these systems include nuclear, solar, wind, and hydro-power.8. Results and discussionFig. 2 shows that nuclear and fossil fuel power plants have the highest cost, with relative weights of 0.429 and 0.337, respectively. On the other hand solar, wind, andhydro have much lower values of relative weights in the range of 0.077–0.079. It is based on the cost hierarchy which indicates that cost of fuel has the highest relative weight of 0.375 among all other costs considered. It is followed by hardware and maintenance costs; their relative weight is 0.215 each. Environmental constraints and the need of auxiliary system have the lowest relative weights with values of 0.122 and 0.074, respectively.Benefits hierarchy (Fig. 3) shows that fossil fuel power plant has the most benefits having a relative weight of 0.255. It is followed by solar and wind power plants; their corresponding relative weights are 0.162 and 0.130, respectively. System’s reliability has the highest relative weight of 0.365. It is followed by availability of fuel, system’s efficiency, its effect on national economy, safety and then social benefits.In order to give the complete picture the overall cost priorities (relative weights) were divided by the benefit priorities. An overall normalized cost-tobenefit ratio was obtained for each system. They are presented in Fig. 4. It is shown that nuclear electrical power plants have the highest overall cost-to-benefit ratio, with a relative weighs value of 0.57. Fossil fuel power plants have the second relative weight of about 0.23. The best systems with lowest cost-to-benefit ratios are solar, followed by wind and then hydro having relative weights of 0.058, 0.061, and 0.083, respectively.9. ConclusionsBased on AHP, solar electrical power plants have the potential to be the best type of system for electricity production in Jordan. They are followed by wind and then hydro-power plants. One can argue that all three technologies or any of the twocombined can be used since they have close relative weights. On the other hand nuclear power plants have the worst rating and fossil fuel power plants are some what little better than nuclear.中文译文利用层次分析法选择各类发电厂摘要本文运用层次分析法(AHP)详细地介绍了利用不同能源进行发电。

层次分析法的实施步骤

层次分析法的实施步骤

层次分析法的实施步骤引言层次分析法(Analytic Hierarchy Process,AHP)是一种多标准决策方法,由美国学者托马斯·萨帕索(Thomas Saaty)于20世纪70年代提出。

它通过将问题分解为多个层次,建立层次结构模型,进行准则间的两两比较,最终得出权重的相对优先级,从而辅助决策者做出决策。

本文将介绍层次分析法的实施步骤,以帮助读者了解如何在实际应用中使用这一方法。

步骤1. 确定目标和准则在使用层次分析法之前,首先需要明确决策的目标和准则。

目标是希望实现的成果,而准则是评估和判断目标实现程度的标准。

例如,如果我们要选择一个新的供应商,我们的目标可以是寻找质量最好、价格最合理、交货速度最快的供应商。

准则可以是质量、价格和交货速度。

2. 建立层次结构模型在确定目标和准则后,下一步是建立层次结构模型。

层次结构模型是一个图形表示,将目标和准则按照层次关系进行组织。

层次结构模型由三个层次组成:目标层、准则层和方案层。

目标层是最高层,表示决策的最终目标;准则层是中间层,包含评估和判断目标实现程度的准则;方案层是最低层,包含备选方案或决策选项。

3. 两两比较准则在建立层次结构模型后,决策者需要对准则进行两两比较,以确定它们之间的相对重要性。

比较的方法通常采用1到9的标度,其中1表示两个准则之间的重要性相等,9表示一个准则相对于另一个准则非常重要。

其他数字表示中间的权重关系。

决策者可以使用判断矩阵记录这些比较结果。

判断矩阵是一个n×n的矩阵,n是准则的数量。

矩阵的每个元素代表两个准则之间的比较结果。

4. 计算权重向量通过两两比较准则后,接下来需要计算权重向量,以确定每个准则对于目标的相对重要性。

计算权重向量的方法是通过对判断矩阵进行数学处理,得出每个准则的权重。

5. 一致性检验在计算权重向量后,需要进行一致性检验,以判断判断矩阵中的比较结果是否合理和一致。

一致性指标是一个反映判断矩阵一致性的数值,通常表示为CI。

用层次分析法选择适当的项目交付方式Mohammed I. Al Khalil*摘要一个项目模型选择最适当的项目交付方式应采用层次分析法(AH P法)。

一些与选择决策相关的因素被使用于项目交付方式的选择排序。

项目业主希望选择一个适当的项目交付方式,因为它可能是一个项目成功的关键因素。

本文中的模型使用简单,并允许业主考虑所有有关决定项目交付方式的因素。

它是基于一个直观的、吸引人的方法:层次分析法。

关键词:项目交付;层次分析法;设计–招标–建造;建设管理1.简介本文涉及的内容是选择适当的项目交付方式。

选择交付方式是定义一个整体项目交付策略中重要的一步。

三个项目交付方式在本研究认为是:设计–招标–建造(DBB)的方式,设计–招标(DB)的方式,以及施工管理(CM)的方式。

要确定这些方式哪个是最合适的,业主必须考虑几个有关决定的因素。

一些研究已经讨论过并提出了这些方法的优点和缺点。

戈登[ 1 ]曾建议使用评判来消除不适当的方式。

斯平克[ 2 ]讨论了在特定情况下让一个特定的交付系统显得适合;并提出图形指南作为援助在设计–招标–建造方式与设计–招标方式之间做出选择。

莫莱纳和松纳[ 3 ]开发一个基于互联网的选择工具,它非常适合于选择设计–建造的交付方式。

层次分析法(AHP法)是由萨蒂[ 4 ]开发的一种多标准的决策方法。

它已应用到解决非结构化问题的各种各样的决策情况下,从简单的个人决定到复杂的密集资本决定。

层次分析法的应用要进行2个阶段:层次化设计与评价[ 4 ]。

层次的设计包含让所有的问题形成一个层次。

在每个层次上,元素被分解为组件,从而构成下一个层次。

在评估阶段,要素在一个层次的成对水平比较要遵循上一级的元素。

等级1- 9用于成对比较。

比较过程中会产生一个相对排名优先的内容方面的标准元素。

最终元素在底部的水平排名(选择)是通过积累要素在各级每个选择的贡献得来。

萨蒂[5]对计算程序进行过深入的讨论。

选择适当的交付方式对业主而言是一个重要的决定;然而,这样的决定可以混淆众多需要考虑的因素。

本文提出层次分析法用以确定适当的项目交付方式。

层次分析法是基于几个因素,大致可以分为以下三大类:项目的特点,业主的需求,和业主的喜好。

本研究中至少有两点原因可以解释层次分析法的选择。

第一,该方法的能力,包括有形的和无形的因素,否则将难以考虑;其次便是层次的结构。

问题是分解成其组成部分降低了从大到小元素的层次。

这样的结构指明了问题,展现了每一个元素贡献的最后决定。

本文是由几个部分组成。

三种项目的交付方式将在下一部分依次遵循层次分析法的模型,其次是层次分析法的使用,以及最后结论。

2.项目交付方式三种基本的交付方式用于这项研究,DBB、DB、CM描述如下。

2.1 DBB方式这是最传统的和最熟悉的项目交付方式。

在这种方式中,业主与设计师和承包商分别签署合同。

设计师准备设计包,包括合同文件。

业主提交方案并在投标人的投标中选择最佳的来承接建设项目。

通常情况下,DBB方式是总额定价。

该方法需要业主监督承包商的活动,确保遵守合同要求。

该方法是众所周知的通过博弈关系来促进双方参与项目。

2.2 DB方式业主与设计和施工方签订单一的整体合同。

该方法可以消除DBB方式里博弈关系的影响,因为单一的合同里双方都负责设计和施工。

它还可以降低项目竣工时间并允许在设计时纳入施工信息,但由于缺乏制衡,保证工程质量成为业主应该关注的问题。

DB方式在范围明确,设计遵循标准,可重复设计和日程安排紧凑的前提下是非常成功的项目交付方式。

2.3 CM方式项目施工经理是由业主聘请的顾问,以他的名义在项目开发过程中进行监督。

该方法通常用于存在多个承包商。

CM方式可以履行若干职责。

它可以提供施工性评价,价值工程研究,工程概算,合同包装。

通过把项目分包签订合同,可以实现快速跟踪进度。

在施工过程中,CM方式可协调承包商的行为并控制工程。

尤其在集约型管理的情况下,CM方式在建设中的作用是至关重要的,比如快速跟踪和成本加成合同。

3.层次分析法的发展AHP层次设计必须满足的目的是开发一个模型,这个模型使建设项目业主决定哪些项目交付方法更适合他们的特殊情况。

层次开发的这项研究包括五个层次,如图1所示。

高层代表选择的目标,项目交付方法。

最后一级为代表的三种方法。

目标选择交付方法是充分满足三个大类项目的特点,业主的需求,和主人的喜好。

因此,这些目标被分配到略低于顶级水平。

第三个层次构成这三大目标的子类别。

根据项目的特点,子类别包括项目范围的定义,时间表,复杂性和定价方法。

业主的需求会因项目的不同而不同,可能包括施工性研究,价值工程研究,合同包装,可行性研究等要求。

业主的喜好包括合同的责任,业主对设计的控制,以及合约签订后的参与程度。

第四级包含的是子类别的实际情况。

层次结构中的元素将在下一节进行讨论。

4.选择项目交付方式的影响因素几个影响因素决定选择一个项目交付方法(PDM)。

这些因素的模型被分为三类:项目的特点,业主的需求,和主人的喜好。

4.1 项目特点4.1.1 清晰范围明确项目的范围和雇主的要求可能会影响决定选择一个系统。

通常一个DB 方法需要一个明确的范围,该范围在设计过程的早期可确定该项目的要求。

其他方法比较合适于含糊不清的范围或者定义不断变化的情况。

4.1.2 日程时间是大多数项目中的主要制约因素。

雇主必须确定快速跟踪进度是否是必要的。

在传统的方法下,因为序列测序阶段,项目的持续时间是漫长的。

通过其他两种方法中的任何一个,可以减少这种正常的持续时间和快速跟踪结果。

4.1.3 复杂性一个项目是否是一个标准的,重复的设计,或一个复杂的独特设计,也是选择首选交付方法的一个考虑因素。

一般来说,DB就是一个合适的标准设计。

在一个复杂的设计中,DBB有可能被使用。

如果业主需要额外的服务,如快速跟踪进度的方法,CM可能是最好的办法。

4.1.4 合同价格合同可作为包干,或成本加定价。

DBB和DB方法可能更适合固定总价合同,而CM通常是成本加成合同的首选方法。

4.2 业主的需求业主可能有额外的要求,因此必须决定组织类型,这将更好地满足这些要求。

PDM选择模型必须是灵活的,因为业主的需求会因项目的不同而不同。

该模型必须能够处理业主的不同需求。

业主的要求可能包括如下:A .可构成性的研究;B .价值工程研究;C .合同包装;D .可行性研究。

4.3 业主的喜好4.3.1 责任有些业主可能更喜欢DB合同单点责任制的特点。

在一个DB系统里,承包商负责设计和施工两方面的错误。

然而在这种情况下,承包商可能存在掩盖错误的倾向。

因此,业主可能更喜欢其他类型的系统,这些系统提供制衡的设计与施工检查。

4.3.2。

设计控制业主必须确定他们想要参与多少到设计过程中,以便影响设计的最终结果。

如果业主希望产生一个创意设计或者他自己已经设计好的外观,一个高层次的参与可能是必要的。

在这种情况下,DBB或CM方式会更合适。

而在DB方式下,业主参与设计的权限会被限制,从而不能深层次的参与设计。

4.3.3。

授予合同后的业主参与业主必须确定如何多的参与到项目中,以便于他们可以负担该项目的执行费用。

有些业主可能有专业知识和足够的可用资源,使他们可以高程度的参与到项目。

其他人可能不具备这种能力,或有但不能使它们合理地提供给项目;因此,这样的业主希望在签订合同后有极少的参与。

PDM的选定需要符合业主参与度的偏好。

5.利用AHP模型AHP模型的使用,要求业主的项目小组讨论和确定层次结构中的每个元素的相对重要性。

在一个级别中的每个元素与其同一水平的元素进行成对比较。

成对比较必须根据表1给出的1至9等级的定义。

表1 层次分析法的比较量表(以参考文献[ 4 ])重量级定义1 同等重要性3 比另外一个重要一些5 必要的,或是强烈的重要7 非常强的重要性9 绝对的重要性2,4,6,8 根据两个相邻之间的中间值进行判断相互的如果元素i有上面的数字之一综上当其被分配与元素j比较,这时j与i比较则有互惠的价值表2 成对比较,第二个层次水平元素的比较目标在第一级PC ON OP 优先级PC 1 4 6 0.556 ON 1/4 1 3 0.380 OP 1/6 1/3 1 0.064 PC:项目特点ON:业主需求OP:业主喜好在表2中,假想成对比较的是模型层次结构中第二个级别的元素。

完成这些成对比较应尊重该模型的总体目标:从而选择最佳的交付方式。

当分配项目的特点与业主的需求相比时,业主在这个特殊的例子里重量级为4。

因此,业主认为“项目特点”在选择一个PDM时比“业主的需要”更重要。

规范化的三要素优先级值可以从这个矩阵计算出来。

即是表2最后一栏所示的优先级值。

以类似的方式,在层次结构的第三个层次的元素,是与第二级及其相关因素成对相比。

例如元素'范围','日程','价格'和'复杂性'就与“项目特点”相比较。

比较值见表3最后一列中列出的优先次序。

因此,通过这一评价过程,每个元素都收到一个规范化的相对其他同一水平相关元素的优先排名。

元素在每个矩阵的优先级值如图2所示。

通过聚集过程,替代元素可以优先。

被选中的替代元素一定是优先级值最高的。

在这个例子中,PDM作为聚集的结果如下:最终优先级DBB 0.27DB 0.39CM 0.34在这种情况下,应该选择的是DB方式表3 项目特点的成对比较范围日程价格复杂性优先级范围 1 4 5 1/4 0.316 日程1/4 1 2 1/6 0.111 价格1/5 1/2 1 1/7 0.072 复杂性 4 6 7 1 0.5006.结论项目特点范围0.316日程0.111复杂性0.072价格0.500范围日程复杂性价格界定0.833 普通0.75 标准0.800 包干0.833 含糊0.167 快速0.25 复杂0.200 加成本0.167业主的需求可构成性0.228价值工程0.077合同包装0.646可行性0.049可构成性价值工程合同包装可行性需求0.800 需求0.833 需求0.857 需求0.857 不需求0.200 不需求0.167 不需求0.143 不需求0.143业主的喜好责任0.233设计控制0.510签包后参与0.257责任对设计的控制签包后的参与度简单0.8 需求0.857 轻0.8检查及制衡0.2 不需求0.143 强烈0.2图2 在层次结构中的所有元素的优先行列AHP模型的开发是以方便业主根据需要进行评估,并选择适当的PDM为目的。

模型通过考虑必要的相关因素来作出决定。

这些影响选择适当的PDM的因素确定是从文献综述而来。

AHP层次设计需要建立一个层次的因素,这些因素必须可以影响到合理选择PDM的过程。
