Battle array, until lowest level.Then, for calculating each judgment matrix Maximum characteristic root and character pair vector, each index is calculated
Subjective weight；Finally, carrying out consistency check.It upchecks, feature vector (after normalization) is weight vector；If examining not
Pass through, needs to reconfigure judgment matrix.1-9 is established according to the following table 2 and compares dimensional configurations judgment matrix, is referred to below with electricity evaluation
Mark, gas evaluation index, hot evaluation index, for seek their weight.
2 1-9 scale table of table
| Quantized value | Factor compares factor |
| 1 | It is of equal importance |
| 3 | It is slightly important |
| 5 | It is relatively strong important |
| 7 | It is strong important |
| 9 | It is extremely important |
| 2,4,6,8 | The median of two adjacent judgements |
It is as follows to establish judgment matrix Y-B:
Solve the maximum eigenvalue λ and maximal eigenvector α of judgment matrix.
The consistency of judgment matrix.
The test coefficient CR for calculating judgment matrix, compares the size of CR and 0.1, if CR < 0.1, is examined by consistency
It tests, otherwise, needs to be modified judgment matrix.
CR=CI/RI, CR are test coefficient, and CI is coincident indicator, and CI=(λ-n)/n-1, n are the dimension of judgment matrix
Number, RI is random index；Wherein, RI is related with the dimension of judgment matrix, and under normal circumstances, dimension is bigger, occurs one
A possibility that cause property deviates at random is also bigger.RI value is as follows:
3 RI value of table
| Dimension | 1 | 2 | 3 | 4 | 5 | 6 | ... | ... |
| RI | 0 | 0 | 0.58 | 0.89 | 1.12 | 1.26 | ... | ... |
It is normalized, obtains the weight of the hot evaluation index of electric-gas-.
Specifically, index is even multiplied by each row:
Seek the geometrical mean of each row:
Normalized obtains the weight coefficient of j-th of index are as follows:
The weight of each index of the bottom similarly can be obtained, the index weights of third layer are multiplied by corresponding second layer index weights
Obtain the subjective weight of the synthesis of j-th of index
(2) objective weight of each index is calculated, as shown in Figure 3.
Entropy be the unordered degree of system one measurement, be a thermodynamics concept originally, after be introduced into information theory, referred to as information
Entropy is widely used in fields such as engineering, economy.Equally objective power is solved by taking second layer subsystem layer appraisement system as an example
Weight, solution procedure are as follows:
1. the initial data to each index of cooling heating and power generation system subsystem layer appraisement system carries out nondimensionalization processing, disappear
Except the dimension impact between each index, matrix is obtainedyijIndicate i-th of sample under j-th of index
This value.
