摘  要:本文给出了带等式和不等式约束的非光滑B-(p,r)规划问题的KKT必要性条件,即:若∈D是(P)的最优解,∑mi=1μigi+∑pj=1vjhj在处是关于η和b的严格B-(p,r)不变凸函数,gi(i∈I),hj(j∈J1),-hj(j∈J2)在处正则。则存在λ>0,μ∈Rm+,v∈Rp,使得是(P)的KKT点。同时,也给出了该类规划问题的KKT充分条件,即:若∈D处KKT条件(2)~(4)式,f+∑mi=1μigi+∑pj=1vjhj在处是关于η和b的B-(p,r)不变凸函数且f,gi(i∈I),hj(j∈J1),-hj(j∈J2)在处正则,那么是(P)的最优解。In this paper necessary KKT condition is given to a class of nonsmooth B-(p, r) programming problems with equality and P inequality constraints as follows: Let x∈ D be optimal solution for (P), ∑i=1^mμigi+∑j=1^pvjhj is strictly B-(p, r) invex function at with respect to η and b, gi(i∈1),hj(j∈J1),-hj(j∈J2) are regular at x. Then there exist λ 〉 0 ,μ∈R+^m,v∈R^p, such that x is KKT point for (P). At the same time, the sufficient KKT condition is given to this programming problem as follows:Let KKT conditions (2) - (4) are satisfied at x∈D, f+∑i=1^μigi+∑j=1^pvjhj is B- ( p, r) invex function at x with respect to -η and b, gi ( i ∈ I), hj(j∈J1), - hi(j ∈ J2 ) are regular at x. Then x is an optimal solution for (P).
