As a preferred embodiment, the index system for establishing assessment includes:
The index system of assessment is established according to the establishment principle of index system and the method for building up of index system.
As a preferred embodiment, the establishment principle of the index system includes: scientific principle, systematicness original Then, Perfect principle, alternative principle and feasibility principle.
Index system foundation is an essential step in Evaluation in Support Ability, and a very crucial step.Index body System is more comprehensive, and the more objective the result of decision the more reasonable, but index just will increase the complexity and difficulty of assessment too much, because This, will follow some basic principles for the selection of index, specific as follows: (1) scientific principle: in conjunction with actual conditions, to guarantor The connection hindered between each element is analyzed, and is analysing the foundation such as set index name, calculation method and intension scientifically On the basis of.(2) principle of systenatization: index system should be able to reflect to comprehensive system that the overall situation of assessment object and various aspects are special Sign, therefrom catches principal element, reflects direct effect, but also reflection indirect effect, not only to guarantee the comprehensive and credible of assessment. (3) Perfect principle: the assessment scale using representational important indicator as system, index system should be able to reflect and estimate Assess the main feature of object various aspects and element.(4) alternative principle: having space-time comparativity between each index, Cannot be compatible, it cannot mutually replace or comprising irrelevant index composing indexes system should be selected as far as possible.(5) feasibility is former Then: the meaning of each index wants easy-to-understand, and achievement data has statistical basis, can obtain the support of relevant information data.It selects as far as possible With quantitative target, qualitative index should be understood that its intension.Wherein crucially Perfect principle and independency principle.So-called completeness I.e. each index can more fully reflect the full content of evaluated system；All indexs are mutual between so-called independence refers to same level It is independent, but since index system is a complicated network, be all mutually related between each index, it is therefore, all based on finger The appraisal procedure of mark system certainly exists defect.
The method for building up of the index system includes: Delphi consultation methods, analytic hierarchy process (AHP) and ADC method.
The Delphi consultation methods are directed to the limitation of evaluator and analyst on knowledge and experience, by organizing each side The expert in face, is allowed to be involved in the problems, such as index system to play consulting effect, repetitious information exchange, statistical disposition and returns It receives synthesis, reasonably provides the correlation between the whole indexs and each index that measures of effectiveness is included.So that it is determined that index body The complete structure of system.The flow chart of this method is as shown in Figure 2.The essence of Delphi consultation methods is systems approach in value judgement Extension, using the experience and wisdom of expert, according to various information and experience abundant that it is grasped, by it is abstract, summarize, comprehensive Close, the thought process of reasoning, obtain the respective opinion of expert, then aggregated analysis and obtain index set.When this method is used, Correctly selecting expert is that this method is successfully crucial.Although this method has the characteristics that using simple, intuitive is strong, its Theoretical property and systematicness be not strong, and mainly expert assesses by the experience of oneself, it is difficult to guarantee the visitor of assessment result The property seen and accuracy cannot provide the qualitative assessment result with clear physical significance.
The analytic hierarchy process (AHP) (AHP), thought are that complicated problem is resolved into one first when establishing index system Each and every one minor issue, each problem are known as an element, then continue to decompose according to membership to each element, until most Until bottom element can be measured relatively easily, recursive hierarchy structure as shown in Figure 3 is thus formed.Index system is most Top layer is exactly system effectiveness (i.e. supportability), is in middle layer and is referred to as rule layer, sub- rule layer, the bottom is scale ginseng Number, is build-in attribute, the specific descriptions of feature, we term it indicator layers.Analytic hierarchy process (AHP) (AHP) has clear thinking, side The advantages that method is easy, widely applicable, systemic strong.It is often used in combination with Experts consultation method, carries out the building to index system.
The ADC method, in addition to basic index system construction method, some assessment technologies also give what another kind was fixed Building method.Such as by the American industry circle Weapons Systems Effectiveness committee (weapon system effectiveness Industry advisory committee, WSEIAC) model and method of the evaluation system efficiency that put forward.The efficiency is commented Estimate method to pass through to system availability A (availability), Reliability D (dependability) and ability C (capability) definition and analysis of 3 indexs, the comprehensive single efficacy measure that system effectiveness is described at one.Wherein A, D Model is fairly simple, can be can be obtained by analysis system working condition and dependability parameter, and C model also needs building and refers to Mark system.ADC method, can also be with the comprehensive use of analytic hierarchy process (AHP) other than it can individually decompose to system effectiveness.
Assessment models foundation generally comprises bottom index assignment method, same layer index weights coefficient calculation method and submodule The contents such as type polymerization.
Index system includes multilayer, and it is to refer in order to clearer to upper layer that each layer, which is the further decomposition to upper one layer, Mark is described.Other than upper layer index value can be obtained by lower layer's indicator polymerization, bottom index needs assignment.Currently, index is assigned Value is that the emphasis of system evaluation areas is also Major Difficulties, it is contemplated that the uncertainty and ambiguity of system, it is impossible to whole Index carries out quantitative precise value, and can only qualitatively be evaluated part index number (such as excellent, good, in, poor), but in reality There is still a need for quantify qualitative evaluation conclusion when polymerization.
As a preferred embodiment, constructing Warships Equipment Maintenance by index assignment method in the step S3 Evaluation in Support Ability model, specifically includes:
Firstly, by have access to inquiry, understandings of having an informal discussion, questionnaire survey, now check, verification of sample, theory is examined, technical ability examines Core or troop exercises obtain index qualitative evaluation or result are quantitatively evaluated；Wherein, the main access inquiry scheme of inquiry is had access to Prediction scheme, system are implemented and situations such as equipment Safeguard.Understanding emphasis of having an informal discussion, which understands to grasp to equip, prepares implementation of conditions and supportability Situations such as construction situation, existing conspicuous contradiction problem and reason, opinions and suggestions and countermeasuress.Questionnaire survey is to select as the occasion requires All kinds of personnel organize blank questionnaire survey, understand the actual conditions for grasping officers and men in terms of supportability.It now checks to adopt Take counterpart test mode organize and implement, emphasis check the equipment support power marshalling, material damage supply, monitoring and metering, troubleshooting repair and Situations such as motor-driven guarantee.Sampling is verified as the case where reporting and in data, extract certain amount it is representative want prime implicant, Verification is compared in control index request.Theory examination is main to rely on theoretical examination exam pool, selects the personnel of being examined, emphasis inspection as the occasion requires It tests officers and men and skillfully grasps rules and regulations and its application.Skill examination is that personnel are examined in determination as the occasion requires, takes actual load to operate, is real The case where forms such as ground operation, high spot review maintainability.Troop exercises are to drill instruction activity in conjunction with war preparedness, and overall process total system is complete Element follow-up investigations armed forces in real combat, actual load, firing practice, the practical capacity that emphasis examines Support Equipment and task to complete.
Secondly, to the index qualitative evaluation or result is quantitatively evaluated using two-stage system, level Four system, hundred-mark system, income class Or cost class method carries out assignment to index.Wherein, two-stage system is suitable for necessary rigid index request up to standard, qualification 100 Divide, is 0 point unqualified.Level Four system be suitable for qualitative evaluation index request, excellent 100 points, it is 80 points good, in 60 points, it is 0 point poor.Percentage The index request that system is suitable for expert or computer scores.Income class is suitable at the equivalent quantization that real data is the bigger the better Reason, score value transformation model are as follows: score=(practical ÷ standard) × 100；It is 100 when real data is greater than or equal to normal data Point.Cost class is suitable for the smaller the better equivalent quantification treatment of real data, score value transformation model are as follows: and score=[1- is (real Border-standard) ÷ standard] × 100；It is 100 points when real data is less than or equal to normal data.
In addition to the above methods, assignment can also be carried out to index by emulation and SEA method.Wherein: the method for emulation It is the common method of assignment to be carried out to bottom index, but its essence is still analytic method, and application equally has limitation；SEA method Also referred to as system discordance method, describes the matching degree of system running track and mission decomposing, and essence is original by system Parameter direct polymerization obtains the comprehensive effectiveness of system.However, since public attribute space is difficult to establish, and since system capability arrives The mapping in the space is usually nonlinear, brings high resistance to the popularization and application of SEA method.
Index weights, which assign power method, common are two classes: the first kind is subjective weighting method, i.e., provides preference information by expert Method；Second class is exactly objective weighted model, and such methods are the methods based on index matrix information.The advantages of subjective weighting method It is that each index weights can reasonably be determined according to the knowledge experience of practical problem and expert itself when in this way, Although accuracy is not high, the sequencing of weight can be substantially provided by significance level, be unlikely to occur index weights with The case where practical significance level is runed counter to.But due to subjective weighting method be by expert according to the knowledge and experience of oneself make to reality The subjective judgement of border problem, therefore its last important order has very big subjectivity random, while being also assessed expert certainly The quality of body and the restriction of knowledge experience；The advantages of objective weighted model is that the objectivity of weight is strong, and does not increase the negative of policymaker Load has stronger mathematical theory foundation.Its shortcoming is that can not consider the subjective intention of policymaker, when determining weight, institute The result obtained may be inconsistent with the subjective wishes of people.
As a preferred embodiment, constructing Warships Equipment Maintenance by weighing computation method in the step S3 Evaluation in Support Ability model, specifically includes:
Warships Equipment Maintenance Evaluation in Support Ability mould is constructed by subjective weighting method, objective weighted model or Evaluation formula Type.
Wherein, subjective weighting method include analytic hierarchy process (AHP) (AHP method), analytic network process, AHP-GEM integration algorithm, Equation, target weight method based on variable weight principle etc. are weighed based on assigning.
(1) analytic hierarchy process (AHP): analytic hierarchy process (AHP) (Analytical Hierarchy Process, abbreviation AHP) is the U.S. The network analysis that a kind of quantification and qualification that Regensburg college professor T.L.Saaty is proposed the 1970s combines Method, be developed so far it is highly developed, using also very extensive in system evaluation areas.Analytic hierarchy process (AHP) refers to same Each index of level is compared two-by-two about the significance level of be subordinate to index in a upper level, constructs multilevel iudge square two-by-two Battle array, carries out the consistency check of judgment matrix, the relative weighting of each index is finally calculated by judgment matrix, when calculating all layers Relative weighting after can linear weighted function and successively polymerize obtain the whole effect of system.It should be noted that judging in construction When matrix, expert opinion is usually considered.Analytic hierarchy process (AHP) is a kind of weigthed sums approach, and advantage is simple and easy, the disadvantage is that in structure It joined subjective factor when making judgment matrix.
(2) analytic network process: conventional construction method is the progressive hierarchical structure based on AHP analytic hierarchy process (AHP), knot Structure is made of destination layer, rule layer and object layer.It is the relationship for dominating with being dominated between at all levels, i.e. upper layer index dominates Lower layer's index, and upper layer index cannot dominate the index not being directly linked in lower layer with oneself, between same layer index mutually It is independent, it is unrelated.However in actual assessment, each factor is often interrelated, influences each other, constitutes one organically It is whole.Simple progressive hierarchical structure can not this kind of complex decision system of accurate description, therefore, using be based on networking index The ANP Analytic Network Process of architecture carries out modeling analysis.Typical ANP structure is as shown in Figure 4.Wherein, it is wrapped in control layer Include the criterion p for influencing decision objective1,p2.…,pm, network layer has element group C1,C2,…,CN, and comprising referring in either element group Mark element
(3) AHP-GEM integration algorithm: the essence of group eigenvalue method (GEM) is that searching scoring vector and group are special Family (S1, S2..., Sm) the smallest ideal expert S* of the sum of angle, using the scoring of S* as the sequence of assessed object.AHP and GEM All it is to combine qualitative and quantitative factor, handles decision problem with a kind of unified mode.AHP has systemic and practical The advantages that property, but it is inconsistent there are judgment matrix the disadvantages of；GEM has larger flexibility with terseness, group decision-making, scale The advantages that, but exist and excessively rely on expert opinion, consider a problem the disadvantages of excessively general.In the way of comprehensive integration by AHP and GEM is combined, and can accomplish to maximize favourable factors and minimize unfavourable ones.
Its combining step is as follows: firstly, the first step according to AHP establishes hierarchy Model；Secondly, determining that expert comments Sub-matrix, it is assumed that using upper layer element O as criterion, lower layer's Elements C for asking expert to dominate criterion O1, C2..., CnDirectly give a mark, Obtain expert analysis mode matrix X；The element sequence for calculating expert analysis mode matrix X with GEM method again, normalizes the power as element Weight；Second is finally repeated from top to bottom according to hierarchy Model to third step, acquires the weight of each layer element.
(4) based on the Index Weights for assigning power equation: often there is certain deviation or mistake in the subjective will of people, no It can objectively reflect the weight of index.In order to eliminate the influence of part human factor, introduces tax power equation and determine indices Weight.It is that each index that will be determined makees an arrangement by its significance level based on the Index Weights for assigning power equation, it is different Index is of equal importance to can also be in same grade, then calculates weight coefficient according to the calculation formula for assigning power equation, it is public to assign power The weight coefficient of formula method due to only related with the estimated levels of the number of decision objective and each target in all decision objectives, Therefore there is preferable objectivity.The disadvantage is that assigning the calculation formula of power equation also needs further to improve, and the sequence of each index When also joined subjective factor.
(5) it is based on variable weight principle target weight method, further investigation revealed that, there are a needs are improved for the above method Problem, the height of supportability depend not only on the height of the comprehensive assessment value of indices, additionally depend on wherein single index Height the index weights based on penalty can also be proposed using " short -board effect " for " short -board effect " of prominent system Assignment method, but how to determine penalty also in reality needs further to study.
Wherein, objective weighted model is mainly based upon index matrix information, such as calculates information Entropy Method, the deviation of information content weight Maximization approach, correlation matrix diagnostic method of independence weight etc..Wherein, information Entropy Method is to be to the definition of entropy in information theory Base configuration goes out a kind of method that index weights are determined using index value, and thought is when certain indexs are in each evaluated side When differing greatly between case, resolving power is strong, and the information for including is just more, their effects in comprehensive assessment, final decision Just big, weight just should be larger, and class pulls open larger between the assessment result that advantage is, is conducive to make a policy, still This method has significant limitation, because the meaning compared between them is not to almost relatively independent between each index Greatly.The thought of maximizing deviation method is only different to the calculation method of the weight of its index as information Entropy Method.Independence The correlation matrix diagnostic method of weight is concentrated in ideal indicator requires determining index irredundant, but due to the complexity of measures of effectiveness Property, inevitably with the presence of part duplicate message between each index in index system, play them too much in overall merit Effect, by being weakened with independence weight, evaluator determines correlation matrix by certain scale to influencing each other index.It lacks Point is that the determination reasonability of scale is to be improved, and joined subjectivity.
However, from the advantage and disadvantage of above-mentioned subjective weighting method and objective weighted model it is found that above two method has centainly It is complementary.In order to make the result of assessment more scientific, assessment experts had not only been taken into account to the preference of index, but also strove reducing entitled subjectivity Randomness can use Evaluation formula.The Evaluation formula based on the principle of least square is explained below and is based on logarithm most Small two multiply the Evaluation formula of principle: the Evaluation formula based on the principle of least square advises target using the principle of least square The scheme of drawing is introduced into combination weighting, to obtain new indicator combination enabling legislation.The principle of combination weighting is according to various The weight coefficient that the significance level of method determines is the weight coefficient of subjective weighting method and the weight coefficient of objective weighted model, and weight coefficient is really It surely is the key that combination weighting combination, weighting coefficient should can reflect that policymaker assigns the subjective preferences of power method to each, The degree of consistency that can reflect various tax power methods again, from the mathematical theory basis of Evaluation formula: obtained by combination weighting Assessment result should as far as possible with subjective weighting method and resulting the being consistent property of assessment result of objective weighted model, if therefore a kind of Assessment result approach degree obtained by the resulting assessment result of tax power method and other several tax power methods is higher, which weighs adding for method Weight coefficient is bigger.Evaluation formula based on the principle of least square first asks combination weighting and master first with the principle of least square The deviation for seeing enabling legislation, then seeks the deviation of combination weighting and objective weighted model, in order to keep combining weights optimal, enable total deviation and It is minimum.Wherein, setting μ is deviation preference heterogeneity, even 0≤μ≤0.5, then illustrates that expert tends to objective weight, as 0.5≤μ ≤ 1, then illustrate that expert tends to subjective weight.This method gets up subjective weight and objective weight weighted comprehensive, weighting system Number is found out by Mathematical Planning, to compensate for the simple deficiency using subjective weighting method or objective weighted model, makes the analysis of assessment As a result simultaneous reactions subjective desire and objective circumstances.Evaluation formula based on the logarithm principle of least square: similarly, if enabling group Close and assign power assessment result and other are assigned power method assessment results and are indicated with the logarithm principle of least square, other with based on minimum two The Evaluation formula for multiplying principle is the same.Least square is that objective function is constructed with the difference of assessment result, and logarithm least square is Objective function is constructed with the quotient of assessment result.The characteristics of Evaluation formula based on the principle of least square is to make various tax Quan Fang Between method have linear compensation effect, the resulting assessment result consistency of Evaluation formula based on the logarithm principle of least square compared with It is good.
Further it is proposed that a kind of model integrated approach, model is comprehensive to be referred to according to the calculating of the index value of bottom finally Supportability process, finally obtain assessment as a result, being the extremely critical step of Evaluation in Support Ability.In addition to calculating weight simultaneously It further include the theory and method comprehensive with drag outside the method for directly carrying out linear comprehensive by coefficient.
(1) it is based on grey --- the synthesis of evidence theory, the current research for Evaluation in Support Ability considers uncertain Factor is less, but actually in the assessment subjective preferences of main body, the complexity of ability itself, the multiplicity of evaluation index information source Property and assessment information fusion etc. all there is certain uncertainty, necessarily affect the reliability of final conclusion.Grey The powerful for such issues that Systems Theory is processing, it is used for by what China was founded famous scholar Deng Julong professor's nineteen eighty-two Handle uncertain information method, principle is the unknown message that system is determined by Given information, thus make system by " ash " change " white ".Evidence theory be by the U.S. Dempster in 1967 propose and by its student G.Shafer improved with It develops, can preferably handle the composition problem with ambiguity and unascertained information.Establishing Evaluation in Support Ability On the basis of index system, method is investigated by expert method, on the spot first and simulation analysis method obtains evaluation index value, and passes through meter The grey relational grade between evaluation index value and capability evaluation grade is calculated, the elementary probability point of evaluation grade under distinct methods is constructed Match, finally the evaluation grade under distinct methods is synthesized using the composition rule of evidence theory, to obtain supportability Assessment result.
(2) uncertain and ambiguity factor quantification, assessment result can more be met visitor by Fuzzy Comprehensive Evaluation It sees, rationally, is determining index weights and construction fuzzy matrix with the key that this method is assessed, in the method for index weights By the agency of mistake, the construction method of fuzzy evaluation matrix have Subordinate Function and expert graded in face, and common membership function has Very much, such as: triangular function, half trapezoidal function, non-linear membership function and some other improved subordinating degree function etc. lack Point is that cannot provide the qualitative assessment with clear physical significance as a result, the foundation of membership function is largely by warp It tests, expert estimation rule subjectivity is too strong.
(3) TOPSIS method, the basic principle of TOPSIS are by means of decision-making problem of multi-objective " ideal solution " and " negative ideal Solution " is ranked up, with the superiority and inferiority degree of each scheme of determination." ideal solution " is a virtual preferred plan, its each finger Scale value all reaches the optimal value in each scheme；" minus ideal result " is therewith on the contrary, its each index value all reaches each scheme In most bad value." ideal solution " and " minus ideal result " represents the extreme case for laying siege to and fighting off in decision process.
(4) Yun Chongxin evaluation assessment, Yun Chongxin evaluation assessment are in uniform data acess as a kind of comprehensive evaluation method What latest development was got up, the uncertain conversion between qualitative and quantitative is embodied, can be realized quantitative attributes and perception extraction Between conversion.The ambiguity and randomness of spatial entities are integrated together by cloud model, combined for qualitative, quantitative Information processing provides powerful, and its essence is be a kind of Fuzzy Comprehensive Evaluation, the cloud model proposed by Li Deyi academician Theory describes the uncertain conversion between certain qualitativing concepts and the expression of its numerical value using natural language, can adequately carve The randomness and ambiguity of qualitative language are drawn, there is biggish objectivity and universal adaptability.Since cloud model has generally Applicability, this method have generalization and commonly used value.
(5) Method of Set Pair Analysis, Set Pair Analysis are a kind of systems about determining uncertain system with different anti-quantitative analysis Analysis method, core be by system certainty and uncertainty give dialectical analyze and Mathematical treatment, it is believed that not really Qualitative is the essential attribute of things, and uncertain and certainty is carried out comprehensive investigation as a system.Set Pair Analysis The certainty of system is divided into " same " and " opposition " two aspect, the uncertainty of system is defined as " difference ", " same ", " difference " and " opposition " (referred to as with different anti-) three connects each other, mutually restricts, and can mutually turn under certain condition Change.The basic conception of Set Pair Analysis is collection pair and its Pair Analysis.So-called collection pair, refers to the two set institute groups centainly contacted At antithetical phrase.Under specific Question background, is classified to collection to the connection in a certain characteristic and quantitatively portrayed, with Pair Analysis Indicate the dialectical relationship of collection pair.The meaning of Pair Analysis is under a certain Question background, and the connection gathered collection centering two carries out phase To determining and do not know dialectical quantitatively to portray relatively.The Method of Set Pair Analysis building of index system, the determination of index value in front And on the basis of the determination of index weights, by determining relatively space, Pair Analysis is further determined in relatively space, finally The degree of association and weight are bonded comprehensive Pair Analysis, assessed on this basis.Evaluation in Support Ability problem if there is It is uncertain, uncertainty will directly affect the stability and reliability of ranking results.Based on Set Pair Analysis thought, structure The multi objective assessment models built, directly define Pair Analysis with initial data, are assessed with quantitative result supportability. Model payes attention to the relativity and ambiguity in information processing, portrays opposition with Pair Analysis and takes into account；Meanwhile principle is intuitive, calculates public Formula and step are easy, as a result rationally, it is objective, can provide one kind new thinking to solve the problems, such as that military field is similarly evaluated.
(6) multi-level extension evaluation method, by the analysis and research to the above method, it can be found that these methods are often not Divided rate range can be dynamically adjusted according to actual needs, the refinement classification of supportability is realized, so that assessment result Specific physical significance has been difficult to it, it is difficult to use, military equipment management and staff are difficult to objectively and accurately grasp supportability Actual state.Optimal appraisal method in extenics method utilizes Region place value and correlation function, in the feelings weighted to each measurement condition Under condition, the superiority and inferiority degree an of object is evaluated.In measurement condition, the condition of " satisfaction " is added, cuts evaluation more It closes practical；Simultaneously as correlation function value can just be born, so as to correctly reflect the superiority and inferiority degree an of assessed object.It can The citation form for opening up appraisal procedure is that level-one can open up comprehensive assessment, for fairly simple problem, can obtain more scientific result； But complicated assessment should be commented numerous index classifications to establish Multilevel Extension since the evaluation index to be considered is more Estimate model.The Synthesis Relational Grade of each grade is calculated, the size of more each grade Synthesis Relational Grade is to determine assessment result.
The present invention establishes manpower and personnel, physical resources on the basis of Maintenance Support Capability Assessment index system respectively Supportability, management ability and the assessment models for ensureing actual effect, provide the weight coefficient calculation method of index of correlation, and Establish maintenance ability Integrated Evaluation Model.The weight for determining each index is the basic work of assessment.Usually it can be used Analytic hierarchy process (AHP) compares same first class index by expert two-by-two, forms weight judgment matrix, and carry out consistency check, examines By rear, so that it may the weighted value of each index be calculated using matrix characteristic vector and normalization.
As a preferred embodiment,
The subjective weighting method includes: analytic hierarchy process (AHP), analytic network process, AHP-GEM integration algorithm, is based on assigning power Equation, the target weight method based on variable weight principle；

As a preferred embodiment, the weighing computation method specifically includes:
Using analytic hierarchy process (AHP), same first class index is compared by expert two-by-two, constructs weight judgment matrix；
To objectively respond the personnel's experience that participates in evaluation and electing, using comparative approach two-by-two, importance measures 1~9 scaling law, such as table It is shown.If index there are k, index i is compared with index j, comparing may have:
Index i is of equal importance compared with index j, takes aij=1；
Index i is slightly important compared with index j, takes aij=3；
Index i is more important compared with index j, takes aij=5；
Index i is compared with index j, hence it is evident that and it is important, take aij=7；
Index i is extremely important compared with index j, takes aij=9.
It takes
aji=1/aij (1)
Among k index, compared two-by-two, then discrimination matrix can be obtained
And meet
aij> 0, aij=1/aji, aii=1 (2)
Scale Meaning
1 Two indices are compared, and have property of equal importance
3 Two indices are compared, the former is slightly more important than the latter
5 Two indices are compared, the former is more more important than the latter
7 Two indices are compared, the former is more obvious than the latter important
9 Two indices are compared, the former is more extremely important than the latter
2,4,6,8 The median of above-mentioned correlated judgment
1 importance scale of table measurement
Secondly, carrying out consistency check to the weight judgment matrix；By the construction of matrix it is found that weight judgment matrix is answered With transitivity.Meet aij.ajm=aim(i, j, m=1,2 ..., k) claims to weigh if weight judgment matrix meets transitivity Weight judgment matrix S is with uniformity.
The definition of above-mentioned consistency matrix is a kind of ideal situation, the judgment matrix in the analysis processing of practical problem Generally it is unable to satisfy above-mentioned requirements.I.e. when determining content index weight using step analysis, often require that judgment matrix has There is approximate consistency, that is, requires that consistency should not be deviateed when multilevel iudge two-by-two too big.It is consistent that judgment matrix is given thus Property examine method:
(a) the Maximum characteristic root λ of weight judgment matrix A is soughtmax；
(b) coincident indicator is found out(order that k is judgment matrix A)；
(c) corresponding Aver-age Random Consistency Index RI is searched；
(d) consistency ration is calculated；
(e) as CR < 0.1, it is considered that the consistency of judgment matrix A is acceptable, otherwise, it should which adjustment is sentenced Disconnected matrix, makes it meet coherence request, to guarantee the credibility of required weight vectors result.
Matrix order 1 2 3 4 5 6 7 8
Index RI 0 0 0.52 0.89 1.12 1.26 1.36 1.41
Matrix order 9 10 11 12 13 14 15
Index RI 1.46 1.49 1.52 1.54 1.56 1.58 1.59
2 random index of table
Finally, each index is calculated using matrix characteristic vector normalization to the weight judgment matrix by examining Weighted value.In the case where judgment matrix S meets coherence request, it can use following method and calculate weights of importance coefficient. Such as the weight coefficient of index j are as follows:
The weight coefficient of k index can be obtained according to the judgement of an expert using above-mentioned steps, due to each expert There is certain subjectivity to the understanding of these index importances.It therefore, can be in order to eliminate the subjectivity to index importance Please multiple experts the importance of these indexs is compared, obtain multiple judgment matrixs, and handled in aforementioned manners.By This is as it can be seen that multiple weight coefficients can be obtained in each index, such as content index j, available weight coefficient is λj1, λj2,…,λjl.Wherein l is expert's quantity.The weight coefficient of index j in this way are as follows:
