1、Designation: E1765 16Standard Practice forApplying Analytical Hierarchy Process (AHP) toMultiattribute Decision Analysis of Investments Related toProjects, Products, and Processes1This standard is issued under the fixed designation E1765; the number immediately following the designation indicates th

2、e year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe analytical hierarchy process (AHP) is one of a

3、 set of multi-attribute decision analysis (MADA)methods that considers nonmonetary attributes (qualitative and quantitative) in addition to commoneconomic evaluation measures (such as life-cycle costing or net benefits) when evaluating project,product, and process alternatives. Investment decisions

4、depend in part on how competing optionsperform with respect to nonmonetary attributes. This practice complements existing ASTM standardson building economics by incorporating the existing economic/monetary measures of worth describedin those standards into a more comprehensive standard method of eva

5、luation that includesnonmonetary (quantitative and nonquantitative) benefits and costs. The AHP is the MADA methoddescribed in this practice.2It has three significant strengths: an efficient attribute weighting process ofpairwise comparisons; hierarchical descriptions of attributes, which keep the n

6、umber of pairwisecomparisons manageable; and available software to facilitate its use.31. Scope1.1 This practice presents a procedure for calculating andinterpreting AHP scores of a projects/products/process totaloverall desirability when making capital investment decisions.3Projects include design,

7、 construction, operation, and disposalof commercial and residential buildings and other engineeredstructures.4Products include materials, components, systems,and equipment.5Processes include procurement, materialsmanagement, work flow, fabrication and assembly, qualitycontrol, and services.1.2 In ad

8、dition to monetary benefits and costs, the procedureallows for the consideration of characteristics or attributeswhich decision makers regard as important, but which are notreadily expressed in monetary terms. Examples of such attri-butes that pertain to the selection among project/product/process a

9、lternatives are: a construction projectss buildingalternatives whose nonmonetary attributes are location/accessibility, site security, maintainability, quality of the soundand visual environment, and image to the public and occu-pants; building products based on their economic and environ-mental per

10、formance; and sustainability-related issues for keyconstruction processes that address environmental needs, whileconsidering project safety, cost, and schedule.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the use

11、r of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.1This practice is under the jurisdiction of ASTM Committee E06 on Perfor-mance of Buildings and is the direct responsibility of Subcommittee E06.81 onBuild

By contrast, life-cycle cost (Practice E917), net savings(Practice E1074), savings-to-investment ratio (Practice E964),internal rate-of-return (Practice E1057), and payback (PracticeE1121) methods all require you

35、 to put a monetary value onbenefits and costs in order to include them in a measure ofproject/product/process worth.5.2 Use AHP to evaluate a finite and generally small set ofdiscrete and predetermined options or alternatives. SpecificAHP applications are ranking and choosing among alterna-tives. Fo

36、r example, rank alternative building locations withAHP to see how they measure up to one another, or use AHPto choose among building materials to see which is best foryour application.5.3 Use AHP if no single alternative exhibits the mostpreferred available value or performance for all attributes. T

37、hisis often the result of an underlying trade-off relationship amongattributes. An example is the trade-off between low desiredenergy costs and large glass window areas (which may raiseheating and cooling costs while lowering lighting costs).5.4 Use AHP to evaluate alternatives whose attributes aren

38、ot all measurable in the same units. Also use AHP whenperformance relative to some or all of the attributes isimpractical, impossible, or too costly to measure. For example,while life-cycle costs are directly measured in monetary units,the number and size of offices are measured in other units, andt

39、he public image of a building may not be practically measur-able in any unit.To help you choose among candidate buildingswith these diverse attributes, use AHP to evaluate youralternatives.5.5 The AHP method is well-suited for application to avariety of sustainability-related topics. Guide E2432 sta

40、teswhen applying the concept of sustainability, it is necessary toassess and balance three dissimilar, yet interrelated generalprinciplesenvironment, economic, and socialbased on thebest information available at the time the decision is made. UseAHP for pairwise comparisons among environmentalattrib

41、utes, among economic attributes, and among socialattributes, and for establishing relative importance weights foreach attribute and for each of the three general principles towhich the attributes are attached. Use the AHP-establishedrelative importance weights to select the preferred project/product

42、/process from among the competing alternatives.5.6 Potential users of AHP include architects, developers,owners, or lessors of buildings, real estate professionals(commercial and residential), facility managers, building ma-terial manufacturers, equipment manufacturers, product andprocess engineers,

43、 life cycle assessment experts, and agenciesmanaging building portfolios.6. Procedure6.1 To carry out a MADA analysis using AHP, follow thisprocedure:86.1.1 Identify the elements of your problem to confirm thata MADA analysis is appropriate (see 6.2),6.1.2 Determine the goal or objective of the anal

44、ysis, selectthe attributes on the basis of which you plan to choose analternative, arrange the attributes in a hierarchy, identify theattribute sets in the hierarchy, identify the leaf attributes in thehierarchy, and identify alternatives to consider (see 6.3),6.1.3 Construct a decision matrix summa

45、rizing availabledata on the performance of each alternative with respect toeach leaf attribute (see 6.4),6.1.4 Compare in pairwise fashion each alternative againstevery other alternative as to how much better one is than theother with respect to each leaf attribute (see 6.5),6.1.5 Make pairwise comp

46、arisons, starting from the bottomof the hierarchy, of the relative importance of each attribute ina given set with respect to the attribute or goal immediatelyabove that set in the hierarchy (see 6.6), and6.1.6 Compute the final overall desirability score for eachalternative (see 6.7).6.2 Confirm th

47、at a MADA analysis is appropriate. Threeelements are typically common to MADA problems.6.2.1 MADA problems involve analysis of a finite andgenerally small set of discrete and predetermined options oralternatives. They do not involve the design of a “best”alternative from among a theoretically infini

48、te set of possibledesigns where the decision maker considers trade-offs amonginteracting continuous decision variables. Selecting a replace-ment HVAC system for an existing building is a MADAproblem. In contrast, the integrated design and sizing of afuture building and its HVAC system is not a MADAp

49、roblem.6.2.2 In MADAproblems, no single alternative is dominant,that is, no alternative exhibits the most preferred value orperformance for all attributes. If one alternative is dominant, aMADA analysis is not needed. You simply choose that alter-native. The lack of a dominant alternative is often the result ofan underlying trade-off relationship among attributes. Anexample is the trade-off between proximity to the centralbusiness district for convenient meetings with business clientsand the desire for a suburban location that is convenient forcommuting to residential ne
