Parameter Decision Making variable is a variable in underlying model, Parameter Decision Making variable is brought into after underlying model, lower floor Model obtains binary decision variable λ ij by particle cluster algorithm according to Parameter Decision Making variable.Specifically, in particle cluster algorithm In, each is with tool per family it is considered that being a particle, the speed of user's traveling is the speed of the particle, by speed Particle continuous computing such that it is able to obtain optimum binary decision variable λ ij, i.e. certain user selects certain charging station to fill The result of electricity.
Refer to Fig. 5, Fig. 5 show Parameter Decision Making variable and binary decision variable are updated to according to preset rules it is pre- If the sub-process of number of times.By according to preset rules undated parameter decision variable and binary decision variable to preset times, to obtain Parameter Decision Making variable that must be stable and binary decision variable.
Specifically, by according to preset rules undated parameter decision variable and binary decision variable to preset times, to obtain The step of Parameter Decision Making variable that must be stable and binary decision variable, includes:Step S310 and step S320.

Furthermore, its binary decision variable is updated by bringing the Parameter Decision Making variable that upper layer model is obtained into underlying model, Its binary decision variable will be updated again brings layer model undated parameter decision variable into.So as to after constantly updating, enable to The optimal solution of upper layer model and the optimal solution of underlying model are close to each other.In the present embodiment, preset times are 100 times.Join Number decision variable and binary decision variable update 100 times.Parameter Decision Making variable and binary decision variable update preset times energy Enough regional stabilities, i.e., after preset times are updated, according to the Parameter Decision Making variable and renewal preset times that update after preset times Upper strata model solution is obtained binary decision variable afterwards investment optimum results can most meet the same of business investor demand When also meet the demand of user.And underlying model is solved according to the binary decision variable updated after preset times and is satisfied with Degree optimum results also comply with the interests of business investor while the demand of user is met.
Step S320:When the Parameter Decision Making variable and the binary decision variable are updated to according to the preset rules During preset times, judgement meets termination condition.
When parameter decision variable and binary decision variable are updated to preset times according to preset rules, i.e., update 100 After secondary.Parameter Decision Making variable and binary decision variable now tends towards stability, so as to judge that the process for updating iteration terminates.
Fig. 6 is referred to, for the implementation procedure of said method, below this is described in detail with a specific embodiment Bright method.
Setting planning region area is about as a example by certain area of city of 150km2 and is charged station optimization layout, and planning region shows It is intended to as shown in fig. 6, business investor can arrange charging station, and each charging station in 6 predeterminated positions (being represented with circle) Usable area it is unfettered.The automobile pollution in default planning level year is about 200,000, and wherein the ratio of electric automobile is about For 10%, electric bus, electric taxi, electronic private car and electronic officer's car percentage are respectively 6%, 13%, 79% and 2%.
The benchmark data and distribution basic parameter of the electric automobile in acquisition planning region is as shown in the table:
μ1 σ1 μ2 σ2 μ3 σ3
155.02 41.53 3.20 0.88 17.6 3.4
Nmin Nmax ωl η r0 τ
5 15 0.15kw*h/km 0.9 0.07 1.0 yuan/kw
e1 e2 Tyear A c0
100000 yuan 30000 yuan/platform * platforms 365 days 2000000 yuan 20 yuan/h

Scheme δi(Ni/ platform) Ten thousand yuan of C/ Satisfaction
1 1(10)、5(9)、6(9) 674.22 56
2 2(7)、4(7)、5(8)、6(8) 722.17 79
Understand that scheme 1 proposes that the cost of investment of newly-built 3 concentrated charging stations is proposed newly than scheme 2 refering to data in table Build low during 4 charging stations, but the satisfaction of charge user is substantially low than scheme 2.The position word of charging station is set in scheme 2 Mother will be marked in Fig. 5, would know that 4 charging station locations are distributed evenly in planning region refering to Fig. 5, although charging station construction Cost increased about 7.11%, but charge user satisfaction greatly improves about 41.07%.

1 1(9)、5(9)、6(9) 686.53 63
2 2(7)、4(7)、7(7)、8(7) 742.36 94
From the data result in upper table, though scene 1 can guarantee that cost of investment is minimum, user satisfaction is relatively It is little;Scene 2 can guarantee that user satisfaction reaches maximum (lifting about 49.21% relative to scene 1), but cost of investment increases (increasing Plus about 8.13%), run counter to business investor theory of investment.Compare with the scheme 2 in above-mentioned specific embodiment, by upper Coupling Decision-making Function in layer model and underlying model between different policymaker, both can guarantee that company investment cost was in reasonable water It is flat, also take into account the comfort level of Consumer's Experience, i.e. enterprise and the respective interests of user have obtained equilibrium.
