In the specific implementation, after the preferred electrically-charging equipment programme of determination, it can be according to preferred electrically-charging equipment planning side
The assessment result of case obtains its scheme optimization information, to provide scheme improved suggestion.
In another embodiment, the scheme optimization information for obtaining the goal-based assessment result, comprising:
Obtain relaxation factor；Using the relaxation factor, the scale and benefit not varying model and the scale and benefit are constructed
The veneziano model of variable model；According to the veneziano model, the scheme optimization information of the goal-based assessment result is generated.
In the specific implementation, obtaining scheme optimization information using a slack variable according to the assessment result of scheme.Firstly,
CCR the and BCC veneziano model comprising relaxation factor s can be constructed, as follows respectively:
Wherein, θkFor the input-occupancy-output analysis coefficient of correspondence of k-th of scheme；For s input-occupancy-output analysis x of k-th of schemesk
Corresponding relaxation factor, economic meanings are the investment redundancy of corresponding index, and then show that scheme optimization direction is to reduce this
Investment；For r output index ies of k-th of schemerkCorresponding relaxation factor, economic meanings are the productions of corresponding index
It is insufficient out, and then show that scheme optimization direction is to improve this output；λiFor the indicator combination coefficient of i-th enterprise；
It is similar to the CCR veneziano model of the s containing relaxation factor, but joined scalable constraintIt is economical
Meaning and scheme optimization direction and the CCR veneziano model of the s containing relaxation factor are also similar.In addition, the scale and benefit of each scheme can be by
KjIt determines,Work as KjWhen=1, the constant returns to scale of scheme is indicated, scheme reaches best output at this time
Scale point；Correspondingly, KjWhen < 1, indicate that the scale and benefit of scheme are incremented by, scheme is constant in current input structure if guaranteeing at this time
In the case where the amount of increasing input, quantum of output will have higher proportion of increase；KjWhen > 1, indicate that the scale and benefit of scheme are passed
Subtract, if the amount of increasing input at this time, quantum of output, which will increase ratio, constantly to be reduced.
In practical application, absolutely evaluation sequence can also be carried out to the validity of scheme.Wherein, the reality of efficiency DEA Model
Existing principle is first to be rejected to it except model when being compared to j-th of decision package, thus further relatively more effective
Decision package relative effectiveness, specific super-efficiency model formula is as follows:
It should be understood that although each step in the flow chart of Fig. 1 is successively shown according to the instruction of arrow, this
A little steps are not that the inevitable sequence according to arrow instruction successively executes.Unless expressly state otherwise herein, these steps
It executes there is no the limitation of stringent sequence, these steps can execute in other order.Moreover, at least part in Fig. 1
Step may include that perhaps these sub-steps of multiple stages or stage are executed in synchronization to multiple sub-steps
It completes, but can execute at different times, the execution sequence in these sub-steps or stage, which is also not necessarily, successively to be carried out,
But it can be executed in turn or alternately at least part of the sub-step or stage of other steps or other steps.
