We define weakly minimal elements of a set with respect to a convex cone by means of the quasi-interior of the cone and characterize them via linear scalarization, generalizing the classical weakly minimal elements from the literature. Then we attach to a general vector optimization problem, a dual vector optimization problem with respect to (generalized) weakly efficient solutions and establish new duality results. By considering particular cases of the primal vector optimization problem, we derive vector dual problems with respect to weakly efficient solutions for both constrained and unconstrained vector optimization problems and the corresponding weak, strong and converse duality statements. 相似文献

This paper presents the conic scalarization method for scalarization of nonlinear multi-objective optimization problems. We introduce a special class of monotonically increasing sublinear scalarizing functions and show that the zero sublevel set of every function from this class is a convex closed and pointed cone which contains the negative ordering cone. We introduce the notion of a separable cone and show that two closed cones (one of them is separable) having only the vertex in common can be separated by a zero sublevel set of some function from this class. It is shown that the scalar optimization problem constructed by using these functions, enables to characterize the complete set of efficient and properly efficient solutions of multi-objective problems without convexity and boundedness conditions. By choosing a suitable scalarizing parameter set consisting of a weighting vector, an augmentation parameter, and a reference point, decision maker may guarantee a most preferred efficient or properly efficient solution. 相似文献

In this paper, two existence theorems concerning the strong efficient solutions and the weakly efficient solutions of generalized vector equilibrium problems are derived by using the Fan-KKM Theorem and an existence theorem for the efficient solutions of generalized vector equilibrium problems is established by using the scalarization method. Moreover, the lower semicontinuity of the strong efficient solution mapping and the weakly efficient solution mapping to parametric generalized vector equilibrium problems are showed under suitable conditions with neither monotonicity nor any information of the solution mappings. Finally, some applications to the vector optimization problems and the Stackelberg equilibrium problem are also given. 相似文献

We consider multi-objective convex optimal control problems. First we state a relationship between the (weakly or properly)
efficient set of the multi-objective problem and the solution of the problem scalarized via a convex combination of objectives
through a vector of parameters (or weights). Then we establish that (i) the solution of the scalarized (parametric) problem
for any given parameter vector is unique and (weakly or properly) efficient and (ii) for each solution in the (weakly or properly)
efficient set, there exists at least one corresponding parameter vector for the scalarized problem yielding the same solution.
Therefore the set of all parametric solutions (obtained by solving the scalarized problem) is equal to the efficient set.
Next we consider an additional objective over the efficient set. Based on the main result, the new objective can instead be
considered over the (parametric) solution set of the scalarized problem. For the purpose of constructing numerical methods,
we point to existing solution differentiability results for parametric optimal control problems. We propose numerical methods
and give an example application to illustrate our approach. 相似文献

We study the weak domination property and weakly efficient solutions in vector optimization problems. In particular scalarization
of these problems is obtained by virtue of some suitable merit functions. Some natural conditions to ensure the existence
of error bounds for merit functions are also given.
