(A4)

(4) 原問(wèn)題等式約束條件

?j∈J, ?t∈T

(A5)

利用KKT條件將雙層模型轉(zhuǎn)換為單層模型式(1),約束條件包括:上層問(wèn)題約束條件式(2)～(6),下層問(wèn)題約束條件式(A2)～(A5).此時(shí)模型為非線性優(yōu)化問(wèn)題,進(jìn)一步采用大M法對(duì)KKT條件中的互補(bǔ)松弛等式約束(A4)進(jìn)行線性化處理:

(A6)

(A7)

根據(jù)強(qiáng)對(duì)偶理論,原問(wèn)題和對(duì)偶問(wèn)題的目標(biāo)函數(shù)在取到最優(yōu)值時(shí),最優(yōu)值大小相等,即

(A8)

(A9)

(A10)
