Based on the index chosen above, carrier-borne aircraft hot drill effectiveness indicator system is preliminarily formed, as shown in Figure 2.
In addition, passing through the expert with naval vessel related personnel and cooperation unit on the basis of being based on index shown in Fig. 2
It discusses research, which is modified.Revised index is as shown in table 1.
Table 1 is based on Kirkpatrick model and the revised index of expertise
The indices for carefully analyzing the proposition of table 1 compare business aircraft, large-scale ships, public affairs according to the bibliography of access
The related fire extinguishing effectiveness evaluation index system of the reference value with higher such as fire department altogether, to Kirkpatrick model structure
The index structure built has carried out reasonable adjustment.Its main cause is as follows:
(1) first under the premise of guaranteeing that index is constant, possess between the indices chosen based on Kirkpatrick model
Progressive feature, this is because the model itself there are the characteristics of it is caused.The index system newly constructed is more focused on efficiency and is commented
Relationship between index before is adjusted to parallel relation by the influence factor estimated.
(2) Kirkpatrick model also fail to instantly it is universal be used in carrier-borne aircraft fire extinguishing field, according to real training fire extinguishing
Correlation circumstance, improved index system are more suitable for the measures of effectiveness of carrier-borne aircraft fire extinguishing to a certain extent.
Based on conditions above, present invention produces the assessment bodies of 5 first class index as shown in Figure 3 and 19 two-level index
System.
After determining index, the present invention determines index weights using analytic hierarchy process (AHP), present invention determine that weight is broadly divided into five
Step:
(1.1) hierarchy Model is established
It has been hit the target the building of a level model structure based on Kirkpatrick model, has been detailed in Fig. 2.
(1.2) discrimination matrix is constructed
Hierarchical structure reflection shown in Fig. 2 influences the relationship between carrier-borne aircraft fire extinguishing assessment efficiency factor, but each level-one is assessed
Index specific gravity shared in measuring using carrier-borne aircraft fire fighting power as general objective is not identical.Here, it is gone out with carrier-borne aircraft
Fiery fighting capacity is general objective, has 5 first class index to have an impact general objective below,
2 discrimination matrix of table constructs table
The scoring criteria of element in 3 judgment matrix of table
5 × 5 discrimination matrix are constructed as example.The determination of other each two-level index weights also using similar method come
Construct discrimination matrix.The present invention takes manner of comparison two-by-two to 5 first class index to construct discrimination matrix.5 are taken every time
Any two in first class index complete discrimination matrix corresponding position element according to the scoring criteria of 3.3 discrimination matrix element of table
Determination, such as office coaching is of equal importance with respect to for itself, then both ratio be 1；Office coaching in organization arrangement
For facility, the former is obvious inessential for the latter, therefore the two ratio is 1/5, conversely, organization arrangement and facility
It is obviously important in office coaching, therefore the two ratio be 5.Other 5 × 5 discrimination matrix elements are also filled in this manner.Together
Reason, also uses the method for the construction of the two-level index discrimination matrix under first class index.
(1.3) Mode of Level Simple Sequence
Carrier-borne aircraft fire fighting power general objective carries out Mode of Level Simple Sequence to 5 first class index of subordinate, carries out as example
Explanation.Assuming that 5 × 5 discrimination matrix of above-mentioned construction are B, the characteristic value and feature vector of calculating matrix B, so that the matrix B accords with
It closes
BW=λmaxW
Wherein λmaxFor the maximum eigenvalue of B, W λmaxCorresponding feature vector, the component W of Wi, WiFor corresponding 5 level-ones
The weight of the single sequence of index.
For check consistency, coincident indicator CI need be calculated, it is following to standardize
, it is evident that when discrimination matrix B meets crash consistency, CI=0.In order to verify discrimination matrix have it is satisfied
Consistency must be compared CI with average coincident indicator RI immediately and find out CR.It is not anticipated when n is equal to 1 and 2 using the present invention
Justice does not consider.For 3-9 rank matrix, RI difference is as follows:
Corresponding RI value when 4 matrix order n difference of table
Judgment rule is as follows: random consistency ration meets consistency when CR≤0.1 for CR, otherwise needs to adjust differentiation square
Battle array.
(1.4) total hierarchial sorting
For carrier-borne aircraft puts out a fire the index system for assessing efficiency, for the sake of simplifying problem, ignore the connection between each index
System, including the connection between 5 first class index and 19 two-level index, then to be just changed into level single for total hierarchial sorting problem
The problem of sequence.
(1.5) consistency check
Due to ignoring the relationship between each index, sequence is converted by total hierarchial sorting problem and is had been presented in step 3
Apparent treating method, and each discrimination matrix is also by consistency check.So each index weights are all handled.
After determining weight, finally judged using Field Using Fuzzy Comprehensive Assessment.Field Using Fuzzy Comprehensive Assessment, which is able to solve, to be difficult to
The problem of quantization, completes the transformation of qualitative to quantitative.
Basic principle and step: judge general objective is influenced by many factors, by these factors to sum up composition set
For U={ U1,U2,…,Um, wherein U1First class index is respectively indicated to Um；Level evaluation, these grades are carried out to first class index
The judge for judging composition integrates as V={ v1,v2,…,vm'}.The judge collection that present embodiment is chosen can substantially be divided into 5 ranks
(it is excellent, good, in, it is poor, fail).Determine each index in the ownership degree R and each index for judging collection in evaluation goal respectively
Weight distribution A.Result of Fuzzy Comprehensive Evaluation collection B is finally calculated according to formula, B is calculated using following formula.
(1) assessment factor set U is divided into m subset U1,U2,…,UmAnd meet U1∪U2…Um=U, to arbitrary i
≠ j,
Sets of factors, each set of factors U wherein are estimated to second leveli={ Ui1, Ui2... ..., Uin(i=1,2 ..., m).
(2) to each set of factors UiIn n evaluation factor, commented according to single level fuzzy synthetic evaluation model
Estimate, if V={ v1,v2,…,vm’It is to judge collection, wherein vj(j=1,2,3 ..., m ') it is the classification standard judged, m ' is vjIn
Contained element number.Evaluation element can be the score value for being qualitatively also possible to quantization.UiIn the weight distribution of each factor be
A=[ai1,ai2,…,aim], wherein element ai1,ai2,…,aimIt is the corresponding weight number of factor.It is mainly used to indicate each factor
The criticality in overall merit must generally keep regression nature and nonnegativity:Its evaluation decision matrix is Ri, then
Set of factors U can be obtainediLevel-one Result of Fuzzy Comprehensive Evaluation are as follows:
Bi=Ai×Ri=[bi1,bi2,…,bin]
(3) by appraisal parameters Ui(i=1,2 ..., m) regards a composite factor as, uses BiSynthesis is carried out as single factor test to comment
Sentence, evaluation decision matrix are as follows:
If the weight proportion of each factor of U is A=[a1,a2,…,am], then available two-level synthetic fuzzy evaluation knot
Fruit:
B=A × R
Wherein B is the comprehensive assessment result of U and the comprehensive assessment result of all assessment factors.Using common matrix model
Method carries out matrix and synthesizes operation.If every sub- set of factors Ui(i=1,2 ..., m) contains more factor or even 4 grades, 5 grades
The model of fuzzy synthetic evaluation of the even more levels of model.
Specific embodiment two, present embodiment are the systems constructed according to the method for specific embodiment one,
Hot drill evaluating system based on carrier-borne aircraft fire, comprising:
Index system establishment module, the second level under each first class index and first class index for being inputted according to user correspond to refer to
